3 2399 PAVEMENT SURFACE SMOOTHNESS DESCRIPTION This work consists of measuring the smoothness of the final concrete or bituminous surface. A Definitions The Department defines Smoothness as the Mean Roughness Index (MRI) value per 0.1 mi [0.16 km] segment. The Department defines Areas of Localized Roughness (ALR) as areas greater than or equal to the limiting criteria for a continuous MRI calculation with a 25 ft [7.62 m] interval, as calculated using the FHWA s Profile Viewing and Analysis (ProVAL) software MATERIAL REQUIREMENTS A Inertial Profiler (IP) Provide a Department certified, calibrated, and documented IP meeting the requirements of ASTM E 950, Class 1 and procedures maintained by the MnDOT Pavement Engineering Section. Refer to the procedures maintained by the MnDOT Pavement Engineering Section or to the MnDOT Smoothness website for the required settings for individual certified IPs. Provide an IP capable of producing a profilogram and exporting raw profile data in an unfiltered electronic Engineering Research Division (ERD) file format. Produce ERD filenames in the YYMMDD-T-N-D-L-B-E.ERD standardized format in accordance with Table : Table Standardized Naming Convention for ERD Files Abbreviation Definition YY Two-digit year MM Month (include leading zeros) DD Day of month (include leading zeros) T Route type (I, MN, US, CSAH, etc.) Route number (no leading zeros) and auxiliary ID (if N applicable) D Primary route direction (I or D) Lane number (1 for driving lane, increasing by one for each L lane to the left; 0 for other lanes such as acceleration/deceleration lanes, ramps, loops) B Beginning station E End station B Profile Analysis Software Use ProVAL software to conduct a profile analysis to determine Smoothness and ALR. Report MRI values in units of in per mi to one digit right of the decimal [m per km to two digits right of the decimal] in accordance with conventional rounding procedures. C Operator Certification Provide an operator, trained in the operation of the particular IP in accordance with A, Inertial Profiler, and knowledgeable in the use of the required profile analysis software in accordance with B, Profile Analysis Software. Ensure profiler operators pass a proficiency test and possess a current certification issued by the Department. The Contractor may access a list of certified operators on the MnDOT Smoothness website. Provide documentation of operator certification to the Engineer. D Submittals

4 D.1 Before Profiling Provide the Engineer with current, valid documentation, issued by the Department, indicating both the IP and the operator certification. D.2 Day of Profiling Submit a printout containing the IP s settings, each segment s left and right wheel path International Roughness Index (IRI) values, and the signature of the operator to the Engineer on the same day of the profiling. Submit electronic files in ERD format representing the raw data from each pass on the same day of the profiling. If the Contractor fails to submit actual data to the Engineer on the day of profiling, the Department will require the Contractor to reprofile the measured segments. D.3 Upon Completion of Pavement Placement Within 5 calendar days of the placement of all mainline pavement and before beginning corrective work, submit a paper ProVAL summary report for each lane, indicating the results of the Smoothness Assurance analyses. Use the ERD filenames in accordance with A, Inertial Profiler to create ProVAL summary reports. If the summary reports indicate no ALR, submit a final spreadsheet summary in accordance with D.5, After Corrective Work. D.4 Before Corrective Work If the summary reports indicate any ALR, submit a written corrective work plan to the Engineer in accordance with E, Corrective Work. Include the beginning and ending points of locations planned for correction in the corrective work plan. Do not begin corrective work before the Engineer approves the plan. If the Engineer elects to assess a monetary deduction for ALR in accordance with Table instead of requiring corrective work, submit a final spreadsheet summary in accordance with D.5, After Corrective Work. D.5 After Corrective Work After reprofiling, submit a paper summary ProVAL report for each lane, indicating the results of updated Smoothness Assurance analyses to the Engineer. Submit the appropriate MnDOT Profile Summary worksheet available on the MnDOT Smoothness website. The worksheet should match the type of construction and the letting year of the project CONSTRUCTION REQUIREMENTS Using an IP, measure the final pavement surface for MRI unless otherwise excluded in Table Unless otherwise approved by the Engineer, perform all profiling in the presence of the Engineer. Schedule profiling with the Engineer. Reprofile any pavement profiled in the absence of the Engineer as directed by the Engineer at no additional cost to the Department. The Engineer will use a 10 ft [3.05 m] straightedge to evaluate areas excluded from surface testing with the IP in accordance with Table

5 A Pavement Surface Testing Remove objects and foreign material from the pavement surface before performing the pavement surface evaluation. Provide traffic control required for testing and performing corrective work on the final pavement surface. Run the IP in the direction of traffic. Measure profiles in the left and right wheel paths of each lane. Test and evaluate each lane separately. The Engineer will determine the length in miles of each mainline traffic lane. Operate the IP at the optimum speed as recommended by the manufacturer. Separate each lane into segments 0.1 mi in length. Evaluate the remainder segment less than 0.1 mi in each lane as an independent segment. The Engineer will prorate pay adjustments for length. Make each pass continuously, regardless of length, and end passes before exclusions in accordance with Table , Areas Excluded from Smoothness and ALR Evaluation. Begin each subsequent pass 50 ft before, and including, construction headers and end of day work joints. For percent improvement projects, measure Smoothness before the beginning of construction and after the completion of construction. Use the same stationing for the final profiling as the stationing used for the initial profiling to allow for a direct comparison of Smoothness when calculating the percent improvement. Measure the Smoothness Before Paving and the Smoothness After Paving values with the same IP. The Engineer will use a 10 ft straightedge to measure for surface deviations in accordance with 2301, Concrete Pavement, and 2360, Plant Mixed Asphalt Pavement.

6 B Exclusions Table indicates areas that are excluded from Smoothness evaluation, but still require measurement with an IP, and are subject to evaluation for ALR and the 10 ft straightedge. Table indicates areas that are excluded from surface testing with the IP, but are subject to evaluation with the 10 ft straightedge. Table Areas Excluded from Smoothness Evaluation For All Pavements Paving in areas with a posted vehicle speed less than or equal to 45 mph Ramps and loops Acceleration and deceleration lanes less than or equal to 1,000 ft in length Projects less than 1,000 ft in length For Bituminous Pavements Single lift overlays placed directly on concrete For Concrete Pavements Intersections constructed under traffic begin and end exclusion 100 ft from the intersection radius Doweled shoulders greater than or equal to 10 ft in width Table Areas Excluded from Smoothness and ALR Evaluation For All Pavements Paving in areas with a posted vehicle speed less than or equal to 35 mph Paving in areas with a cautionary vehicle speed less than or equal to 35 mph Turn lanes, crossovers 10 ft on either side of obstructions in lane that obstruction is located Side streets, side connections 150 ft before stop signs at an intersection 150 ft before yield signs at a roundabout Bridge decks and approach panels 20 ft from bridge decks and approach panels 20 ft from terminal headers tying into existing pavement For Bituminous Pavements Paved shoulders Intersections where mainline profiles are merged or blended into the cross street profile begin and end exclusion 100 ft from the intersection radius For Concrete Pavements Doweled shoulders less than 10 ft in width Undoweled shoulders Headers adjacent to colored concrete C Calculations C.1 Smoothness Obtain Smoothness values in an individual lane using the ProVAL Smoothness Assurance analysis with the 250 mm filter. For percent improvement projects, use the Smoothness Before Paving and Smoothness After Paving values to calculate the percent ride improvement.

7 C.2 Areas of Localized Roughness Identify ALR using the ProVAL Smoothness Assurance analysis, calculating MRI with a continuous short interval of 25 ft [7.62 m] with the 250 mm filter. D Pay Adjustments D.1 Smoothness Evaluate Smoothness requirements using the equations and criteria in accordance with the following tables: (1)... Table for bituminous pavements, (2)... Table for concrete pavements, and (3)... Table for percent improvement projects. The Engineer will base pay adjustments on the segment Smoothness value (or percent improvement value, for percent improvement projects) measured at the completion of surface pavement, unless corrective work is required by the ProVAL summary report results. If a segment is less than 100 ft in length and Table , Table , or Table requires corrective work, the Engineer will waive the corrective work requirement for the segment and instead assess a prorated disincentive. The Department will still subject the segment to ALR analysis in accordance with Table For segments requiring corrective work, reprofile the entire 0.1 mi segment after performing corrective work as directed by the Engineer and enter the reprofiled Smoothness values into the final Profile Summary worksheet.

8 D.1.a Bituminous Pavements Table contains pay adjustments for bituminous pavements. See Section 2360, Plant Mixed Asphalt Pavement of the Special Provisions for the ride equation requirements. Table Smoothness Pay Adjustments and Corrective Work for Bituminous Pavements Smoothness Pay Adjustment Equation in/mi $/0.1 mi < HMA-A Smoothness > 75.0 Corrective Work to 50.0 in/mi < HMA-B Smoothness > 80.0 Corrective Work to 55.0 in/mi < HMA-C x Smoothness > 95.0 Corrective Work to 65.0 in/mi For bituminous projects, the Engineer will not pay any positive Total Pay Adjustments if greater than 25 percent of all mainline density lots for the project fail to meet the minimum density requirements in accordance with 2360, Plant Mixed Asphalt Pavement.

9 D.1.b Concrete Pavements For concrete pavements, the Engineer will use equation PCC-A. Table Smoothness Pay Adjustments and Corrective Work for Concrete Pavements Smoothness Pay Adjustment Equation in/mi $/0.1 mi < PCC-A Smoothness > 85.0 Corrective Work to 65.0 in/mi If the Contractor adds water to the pavement surface without approval by the Engineer, the Engineer will not pay any positive Pay Adjustments for 0.1 mile segments where the water was added and the Engineer may reject the pavement in accordance with 1512, Unacceptable and Unauthorized Work. D.1.c Percent Improvement Projects The Engineer will base pay adjustments on the segment percent improvement values. The Engineer will calculate the percent improvement in accordance with the following equation: Smoothness Before Paving Smoothness After Paving % I = 100 Smoothness Before Paving Determine the Smoothness Before Paving value before patching or other repair. Determine the Smoothness After Paving value after the completion of paving and any corrective work. Table Smoothness Pay Adjustments and Corrective Work for Percent Improvement Projects Equation Percent Improvement (%I) Pay Adjustment $/0.1 mi > PI 0.0 to (%I) < 0.0 Corrective Work to %I of at least 0.0 For bituminous percent improvement projects, the Engineer will not pay any positive Total Pay Adjustments if greater than 25 percent of all mainline density lots for the project fail to meet minimum density requirements in accordance with 2360, Plant Mixed Asphalt Pavement. Correct segments with a percentage improvement of less than 0.0 percent at no additional cost to the Department as required by the Engineer.

10 D.2 Areas of Localized Roughness The Engineer will evaluate ALR in accordance with Table , ALR Monetary Deductions and Corrective Work Requirements. Table ALR Monetary Deductions and Corrective Work Requirements 25 ft Continuous MRI Corrective Work or Monetary Equation in/mi Deduction, per linear 1.0 ft < Acceptable HMA-A or HMA-B, and a posted vehicle speed > 45 mph to < Corrective Work unless both the Engineer and the Contractor agree to a monetary deduct of $25.00 Corrective Work unless both the Engineer and the Contractor agree to a monetary deduct of $ < Acceptable PCC-A and a posted vehicle speed > 45 mph to < Corrective Work unless both the Engineer and the Contractor agree to a monetary deduct of $ Corrective Work HMA-C, PI, ramps, loops, concrete intersections constructed under traffic, or any paving with a posted vehicle speed 45 mph < Acceptable $25.00 The Engineer will consider areas of ALR acceptable if the reprofiled segment contains no ALR. The Department will reduce payment for ALR remaining after reprofiling as determined by the Engineer and in accordance with Table , ALR Monetary Deductions and Corrective Work Requirements. D.3 Straightedge Evaluation The Engineer will allow variations less than or equal to ¼ in [6.35 mm] within the span of the straightedge in the longitudinal or transverse direction to remain in place without correction or penalty.

11 The Engineer will require corrective work on surface deviations greater than ¼ in [6.35 mm] within the span of the straightedge in any direction. For corrected variations, the Engineer will accept deviations less than or equal to ¼ in [6.35 mm] within the span of a 10 ft [3.05 m] straightedge in any direction. E Corrective Work Notify the Engineer at least 24 hr before beginning corrective work. Do not begin corrective work before the Engineer approves the methods and procedures in writing. Perform corrective work using a surface diamond grinding device consisting of multiple diamond blades, unless otherwise approved by the Engineer. Fog-seal diamond ground bituminous surfaces as required by the Engineer and at no additional cost to the Department. Repair and replace joint sealant damaged by diamond grinding on concrete pavement as directed by the Engineer and at no additional cost to the Department. The Contractor may correct bituminous pavements by overlaying the area or replacing the area by milling and inlaying as approved by the Engineer. If milling and inlaying or overlaying, perform work in accordance with 2399, Pavement Surface Smoothness, over the entire length of the correction. If milling and inlaying or overlaying, use a transverse saw cut to begin and end the surface correction. Perform corrective work across the entire lane width. Maintain the pavement cross slope through corrective areas. Perform coring to determine if diamond grinding corrective work results in thin pavements, as directed by the Engineer. Provide additional coring for thickness verification at no additional cost to the Department. The Department may reduce the payment for thin pavement sections after diamond grinding. Handle residue and excess water resulting from diamond grinding in accordance with 1717, Air, Land, and Water Pollution. Perform surface corrections before placing permanent pavement markings. Replace permanent pavement marking damaged or destroyed by corrective work at no additional cost to the Department. Reprofile segments containing corrected areas with the same certified IP in accordance with A, Inertial Profiler within 5 calendar days after the completion of corrective work required by the Engineer. F Retesting Perform retesting as directed by the Engineer and within 30 days of the original profiling. If the retested Smoothness values differ from the original Smoothness values by greater than 10 percent, the Engineer will use the retested values as the basis for acceptance and pay adjustments. If the retested values differ from the original values by greater than 10 percent, the Department will not pay for the cost of retesting. If the retested Smoothness values differ by less than or equal to 10 percent of the original Smoothness values, the Engineer will use the original values. If the Engineer verifies the accuracy of the original results, the Department will pay for retesting as directed by the Engineer, except for retesting required after corrective work, at $ per lane mi [$62.14 per lane km] retested or $500.00, whichever provides the greater amount METHOD OF MEASUREMENT (BLANK) BASIS OF PAYMENT The Department will include the cost of the IP, testing, and traffic control in the relevant contract unit price for wearing course mixture for bituminous pavements, concrete pavement for concrete pavements, or for concrete grinding.

12 At Any Time If you have a smoothness related question or would like assistance with any of the steps enumerated in this document, please contact one of the following individuals. o Tom Nordstrom, Pavement Management Analyst: o Rob Golish, Assistant Concrete Engineer: o Greg Schneider, Assistant Bituminous Engineer: Before Any Profiling is Performed by Contractor Familiarize yourself with the following pavement terms: o International Roughness Index (IRI): roughness measurement that represents how the road feels to drivers and passengers o Mean Roughness Index (MRI): average of left and right wheel path IRI o Smoothness: 528-foot MRI o Area(s) of Localized Roughness (ALR): 25-foot continuous MRI in/mi o ERD file: text file that contains pavement elevation data o ProVAL (Profile Viewing and Analysis): FHWA software application used to view and analyze pavement profiles Ask inertial profiler (IP) operator to provide evidence of current, valid operator and inertial profiler certifications. Operator certification is valid for multiple years, but inertial profiler certification expires at the end of each calendar year. Both certifications can be verified by accessing the Profiler Certification page of MnDOT s Smoothness website: Version Page 1 of 18

13 On the Day Profiling is Performed by Contractor Receive a printout of each pass of data collected by the Contractor. While the data on this printout is not be used to calculate actual Pay Adjustments, it provides immediate, in-the-field approximations of a project s Smoothness and ALR values. You should focus on the following four portions of the printout: o Data collection software version, o Sensor serial number(s), o Low- and high-pass filters, and o 528-foot IRI & MRI values. It is critical that the software version and IP serial number(s) match those used during IP certification. Once certified, all IP settings are posted to the Profiler Certification page of MnDOT s Smoothness website, which can be accessed at: Confirm that the low- and high-pass filters are set to zero. If they are not, request a new printout. Low- and high-pass filters smooth out the profile, which can result in lower Smoothness values and higher Pay Adjustments. Finally, examine the left and right wheel path 528-foot IRI values, as well as the 528- foot MRI values, for an indication of the pavement s overall ride quality. The 528-foot MRI values listed on this printout should be nearly the same as the Smoothness values that will be entered into the Profile Summary worksheets by the Contractor at a later date. Figure 1 shows a sample printout from MnDOT s Ames high speed inertial profiler with the important portions of the printout highlighted. The left wheel path IRI, right wheel path IRI, and MRI tables are labeled Track 1, Track 2, and Average, respectively. Receive an ERD file for each pass of data collected by the Contractor. ERD files are imported into a software application called ProVAL to generate Smoothness and ALR values. Each ERD file must be named in the YYMMDD-T-N-D-L-B-E.ERD standardized format in accordance with Table Version Page 2 of 18

14 Table 1. Standardized Naming Convention for ERD Files Abbreviation YY MM DD T N D L B E Definition Two-digit year Month (include leading zeros) Day of month (include leading zeros) Route type (I, MN, US, CSAH, etc.) Route number and auxiliary ID if applicable (E, W, etc.) Primary route direction (I or D, indicating Increasing or Decreasing; Increasing = North or East, Decreasing = South or West) Lane number (1 for driving lane, increasing by one for each lane to the left; use 0 for other lanes, such as accel/decel or ramps/loops) Beginning station End station For example, I-35W-I ERD would indicate a beginning station of 5+21 and an end station of , in the driving lane, in the increasing (northbound) direction of I-35W, tested on July 21, If the Contractor fails to submit the required data on the day of profiling, the measured segments must be reprofiled by the Contractor at a later date. Upon Completion of Pavement Placement by Contractor Within 5 calendar days of pavement placement, receive ProVAL summary reports containing Smoothness Assurance analyses. ProVAL summary reports contain the Smoothness and ALR data that will be entered into the Profile Summary worksheets by the Contractor (once any necessary Corrective Work is completed). See Figures 2 through 7 for a sample ProVAL report, paying particular attention to the highlighted portions Version Page 3 of 18

15 The data in the ProVAL report is presented in four distinct sections. The first section Analysis: Smoothness Assurance contains a short table that lists all of the pavement sections and indicates whether each was analyzed with a 250-mm filter. If any of the sections were analyzed without the application of this filter, ask the Contractor to generate and submit a corrected ProVAL report. Sections two and three of the ProVAL report titled Short Continuous and Long Continuous contain ALR data, while the fourth section Fixed Interval contains Smoothness data. Although it appears at the end of the report, examine the Fixed Interval section before the sections containing ALR. The first step is to confirm that the appropriate settings have been entered by the Contractor (see Figure 7). The Segment Length should always be 528 feet since the Profile Summary worksheets segment Pay Adjustments are calculated on a tenth-of-a-mile basis. The Threshold should equal the maximum Smoothness value before mandatory Corrective Work is triggered for a particular equation (Table 2 lists the Smoothness Corrective Work thresholds for each Smoothness equation). For instance, the Threshold for an HMA-A project is 75.0 in/mi. It is essential that both the Segment Length and Threshold settings are correct. If either of these is incorrect, request a new ProVAL report with the appropriate values. Table 2. Smoothness Corrective Work Thresholds Equation Smoothness Corrective Work Threshold (in/mi) HMA-A 75.0 HMA-B 80.0 HMA-C 95.0 PCC-A 85.0 After verifying the Fixed Interval settings, examine the Smoothness values presented in the Fixed Interval chart and table. The chart is useful for quickly surmising whether any of the 528-foot segments must undergo Corrective Work. The actual Smoothness values are listed in the table beneath the chart in the column labeled, No Grinding MRI (in/mi). The Smoothness values in this table should match very closely within a tenth of an in/mi per comparison to the 528-foot MRI values on the printout the Contractor submitted on the day of profiling Version Page 4 of 18

16 Let s suppose that the Smoothness data contained in the sample ProVAL report is for an HMA-A project. Examining the chart in Figure 7, it is obvious that two of the 528- foot segments the third and fourth exceed the Smoothness Corrective Work threshold of 75.0 in/mi. The bars that represent these segments are above the red, horizontal line, indicating that Corrective Work is necessary. Referring to the data table below the chart, you will find that the Smoothness values for these segments are and 81.35, respectively. At this point, it is recommended that you compare the ProVAL report s Smoothness values against the Pay Adjustment table(s) that will be used for the project. Tables 3 and 4 consist of the various Pay Adjustments and Corrective Work requirements used for bituminous and concrete projects. Table 3. Smoothness Pay Adjustments & Corrective Work Requirements for Bituminous Pavements Equation Smoothness (in/mi) Pay Adjustment ($/0.1 mi) HMA-A HMA-B HMA-C < ( Smoothness) > 75.0 Corrective Work to 50.0 in/mi < ( Smoothness) > 80.0 Corrective Work to 55.0 in/mi < (6.000 x Smoothness) > 95.0 Corrective Work to 65.0 in/mi Table 4. Smoothness Pay Adjustments & Corrective Work Requirements for Concrete Pavements Equation Smoothness (in/mi) Pay Adjustment ($/0.1 mi) PCC-A < ( Smoothness) > 85.0 Corrective Work to 65.0 in/mi 2016 Version Page 5 of 18

17 The next step is to inspect the Short Continuous section of the ProVAL report for ALR data. Begin by verifying that Segment Length and Threshold are 25 feet and in/mi, respectively. If the values match, examine the Short Continuous graph, which displays 25-foot continuous MRI values. This graph contains a red, horizontal line that intersects the y-axis at in/mi MRI. Any data points located at or above this line are defined as ALR. This graph is useful because it provides a visual representation of the amount and magnitude of the localized roughness (usually in the form of bumps and dips) that exist. The Short Continuous graph of our sample profile (see Figure 3) shows two adjacent ALR both having a maximum height of just over in/mi. Below the graph is a table titled No Grinding that contains the ALR starting and ending locations, along with the 25-foot continuous MRI value for the apex of each ALR. According to this table, the peak values for the ALR are and in/mi, respectively. After noting the locations and magnitudes of individual ALR, check the amount of pavement that falls within MnDOT s ALR Monetary Deduction categories. This information can be found in the short table located at the end of the Short Continuous section (see Figure 4). For our sample profile, the length of pavement to < in/mi is linear feet, while the amount in/mi is linear feet. Information on the various ALR categories and their corresponding Monetary Deductions and Corrective Work Requirements is located in Table 5. The final part of the ProVAL report the Long Continuous section is the least important. The data in the Long Continuous graph is the same as the data that comprises the Short Continuous graph, with one exception: the red, horizontal line on the Long Continuous graph intercepts the y-axis at the upper ALR threshold of in/mi instead at the lower ALR threshold of in/mi MRI (see Figure 5). While not critical, a quick scan of the Long Continuous graph can help the viewer determine how much ALR, if any, falls in the upper deduct category. The settings for this section should be 25 feet for Segment Length and in/mi for Threshold Version Page 6 of 18

18 Table 5. ALR Monetary Deductions and Corrective Work Requirements Equation 25-foot Continuous MRI (in/mi) Corrective Work or Monetary Deduction, per linear 1.0 foot < Acceptable HMA-A or HMA-B, and a posted vehicle speed > 45 mph to < Corrective Work unless both the Engineer and the Contractor agree to a deduct of $ Corrective Work unless both the Engineer and the Contractor agree to a deduct of $ < Acceptable PCC-A and a posted vehicle speed > 45 mph to < Corrective Work unless both the Engineer and the Contractor agree to a deduct of $ Corrective Work HMA-C, PI, ramps, loops, concrete intersections constructed under traffic, or any paving with a posted vehicle speed 45 mph < Acceptable $ Version Page 7 of 18

19 Determine whether Corrective Work is necessary. Two types of Corrective Work exist: Smoothness Corrective Work and ALR Corrective Work. Smoothness Corrective Work always is required when one or more Smoothness values exceed an equation s Smoothness Corrective Work threshold. In contrast, ALR Corrective Work can be substituted with a monetary deduction if both the Engineer and the Contractor agree (see Table 5). However, if either party desires Corrective Work, a monetary deduction will not be allowed in lieu of Corrective Work. Note: PCC-A projects with a Posted Vehicle Speed > 45 mph that have ALR in/mi must undergo Corrective Work until all ALR are eliminated. Figure 8 is a flowchart that was designed to simplify this oft confusing process. As you can see from the chart, Corrective Work never is required when both of the following are true: 1. Smoothness Corrective Work is NOT required by a Pay Adjustment table. 2. No ALR exists, or the Posted Vehicle Speed 45 mph, or the Smoothness Equation is either PI or HMA-C. Receive Profile Summary worksheets (if no Corrective Work is necessary). If Corrective Work is indeed unnecessary, ask the Contractor to use the data in the initial ProVAL report to fill out the Profile Summary worksheets (see Figure 9 for a sample worksheet). Upon completion, collect the worksheets from the Contractor. Review Profile Summary worksheets (if no Corrective Work is necessary). First, verify the data entered into the Profile Summary worksheets by comparing it to the data in the ProVAL summary report. Next, confirm that all of the worksheets green cells have data entered into them and that the correct lane description, Smoothness equation, and posted vehicle speed have been selected from the dropdown lists. Finally, it is critical that none of the white output cells indicates Corrective Work is necessary. The Profile Summary worksheets are programmed to not display a Total Pay Adjustment + Areas of Localized Roughness Deduction value if either Smoothness or ALR Corrective Work is required. This is to prevent disbursement of Pay Adjustments until after all necessary Corrective Work has been completed. Keep in mind that the Corrective Work indicated by a Profile Summary worksheet is not optional. If Corrective Work is indicated, it must be performed by the Contractor Version Page 8 of 18

20 Before Corrective Work is Performed by Contractor Receive a Corrective Work plan. You must approve this plan before the Contractor begins any Corrective Work. If no Smoothness Corrective Work is required and ALR Corrective Work is not mandatory, you may assess ALR Monetary Deductions in lieu of Corrective Work, provided the Contractor agrees to this substitution. If the Contractor does not agree to this substitution, ALR Corrective Work must be performed. Receive Profile Summary worksheets (only if Corrective Work is not mandatory and the Contractor agrees to ALR Monetary Deductions instead of Corrective Work). If it is agreed that ALR Monetary Deductions will be substituted for Corrective Work, ask the Contractor to use the data in the initial ProVAL report to fill out the Profile Summary worksheets. Upon completion, collect the worksheets from the Contractor. Review Profile Summary worksheets (only if Corrective Work is not mandatory and the Contractor agrees to ALR Monetary Deductions instead of Corrective Work). Refer to the section titled Upon Completion of Pavement Placement by Contractor for instructions on how to review Profile Summary worksheets. After Corrective Work is Performed by Contractor Receive new printouts and ERD files for Corrective Work segments. Following Corrective Work, the Contractor must reprofile all the 528-foot segments in which Corrective Work was performed. On the day of reprofiling, you will need to collect printouts and ERD files for these segments. Receive an updated ProVAL summary report that contains Smoothness Assurance analyses for each 528-foot segment in which Corrective Work was performed. Receive Profile Summary worksheets. Have the Contractor use the data in both the initial and updated ProVAL reports to fill out the Profile Summary worksheets. Upon completion, collect the worksheets from the Contractor. Review Profile Summary worksheets. Refer to the section titled Upon Completion of Pavement Placement by Contractor for instructions on how to review Profile Summary worksheets Version Page 9 of 18
