L 7. P.4. L MEMO TO: A.. Nei.ser Assistant State Highway Engineer The attached report, "Pavement Roughness Studies," by Rolands L, Rizenbergs Research Engineer Associate, is a pro, gress report on research performed in this field during 196L Possibly the most significant effort has been the evaluation of three segments of new Interstate pavement opened to traffic during the year. A separate plot of the roughness index values for Interstate pavements has been prepared and is shown in Fig. 6, page 18. Roughness index values for component layers of Clark County, I645(7)93, are shown in page 16. These data. indicate that through careful leveling, etc., significant reduction in roughness values can be accomplished. The roughness index values for Interstate pavements have been reported previously to the Construction Division. These data \Alere requested for use in final pavement inspectl<yn prior to acceptance and before the projects had been opened to traffic. Mr. Rizenbergs has descr::.bed a pavernen.t serviceability study that resulted in the rati.ng of th1eee pavements by methods used at the AASHO Road Test: ProjecL We find, on a limited basis that there is son1e correltition. between the roughness index and present serviceability i:ndex"
3 A.. Neiser 2 February 23, 1962 We, were invited. to participate in a cooperative pavement roughness evaluation along with Michigan, Illinois, Indiana, AASHO Road Test Staff, and the Bureau of Public Roads in northern Indiana, in August, We have comparative values from methods in use by each of the groups for correlation with our values. Following this work, we have had inquiries indicating that the Indiana Joint Highway Research Project is considering obtaining roughness equip rnent patterned after the Kentucky udt. California has built two of these units, We plan to continue evaluation of projects under study and to begin roughness measurements on major projects completed during the next year, WBD:dl Enc, cc: Research Committee Members Bureau of Pablic Roads (3) Respectfully submitted, W, B, Drake Director of Research
4 3. During 1961, the equivalent of about 8 lanemiles of pavement were tested and analyzed, The largest portion of this mileage was on completed Interstate projects, In November, three pavements selected by the Bureau of Public Roads for serviceabilityindex ratings (6) were tested; and these are discussed briefly in this report, Periodic surveillance of the roughness of all of the roads presently listed in Tables land 2 is contemplated, New primary and Interstate construction will be included in the future, Thus, each respective project may be eventuau.y characterized by a history of roughness measurements.
5 RESULTS AND ANALYSES All of the data applicable to the projects under study are shown in Tables 1 and 2. A map showing the approximate locations of the completed Interstate projects is presented in Fig. l. Rating of Prim and Secondary Roads The roughness of portland cement concrete and bituminous pavements both primary and secondarys were considered in a combined plot in Fig. 2. This data was subdivided into approximately equal quartiles (containing equal number of projects) which are indicated by the "word" classification given at the bottom of Fig. 2. An overlap was allotted to each quartile in order to avoid sharp distinction between pavements having nearly the same roughness indexes. The median roughness index of 6 was computed from all the available data without any distinction as to the types or ages of pavements. There are as ma!ly roads having roughness indexes,greater than 6 as there are roads having less than this value. Accordingly, the median value was sel,ected as the midpoint for the "word" classification. Hence, the first quartile to the left and right of the median were designated "good" and "fair" respectively, and the outer quartilesa in the same respective order, were designated as 11 excellent" and "poor". The inclusion of several additional roads has increased the median roughness over that of the previous year thereby, C<\Using a shift in the quartile boundaries. 4,.

13 12 The completed Interstate projects include 18 miles of bituminous concrete and 114 miles of portland cement concrete, Scaled diagrams of the sections are given in Figs, 3, 4, and 5; roughness indexes obtained for each lane and other pertinent information is shown thereon, It can easi.ly be seen that the degree of roughness often varied greatly within the same project; although some sections exhibited uniform roughness or smoothness throughout the project, Of course, dual" paved lanes came closer to having the same roughness, yet differences were noted in these companion lanes, Large differences were foun.d among the sections, A new low roughness index was obtained on I643(6)47, roughness index 249, and a high of 414 was found on I758{13)181, It was interesting to note that two of the smoothest projects, I643(6)47 and I643(9)37, were paved by the same contractor, Likewise, two of the roughest surfaces, I643(1)42 and I758(13)181, were paved by another contractor, It seems, therefore, that the practices, methods, and equipment, etc,, employed by the respective contractors are contributing factors since the same specifications and tolerances applied to all alike.

17 might be attributed to the method of detecting depressions in each roughest surfaces. Perhaps some of the decrease in roughness resurfacings usually produce the greatest improvements on the course and the least on the surface course. This was expected since surface. The greatest improvemenc was noted on the second base Each successive course improved the riding quality of the of each course. The following roughness indexes were obtained: First Base Course. Second Base Course rrz Combined R.I. 47 Binder Course. 328 Surface Course 299 Winchester to Mt. Sterling, was followed closely through the paving The bituminous concrete pavement construction on I645(7)93, correlates rather well with the roughness index. The amplitude distribution plots of the percent of. 5g accelerations concentration was on pavements having the lower combined indexes. distribution. Typically, the widest distribution was found on pavements with the higher combined roughness indexes, and the largest plots portray the intensity of pavement roughness, its range, and and are arranged there according to increasing roughness index, These measured are presented. The plots are presented in the Appendix acceleration amplitude analysis in percent of the total amplitudes category versus its corresponding roughness index. Also the vertical 16 <
18 17 course that is, with a 5,,fL stringline and patching them before the next course was applied, Since this procedure was followed throughout the project, it was not possible to say just how much, if any, of the improvement is attributable directly to the stringlining. This practice was continued on project I645(8) 1; and both surfaces displayed good riding qualities. The completion of several Interstate projects established a rather definite pattern as to what may be anticipated from hightype construction wi.th regard to pavement roughness, It is of interest to differentiate Interstate construction from all other types of constructi9n and to establish a separate riding quality rating for them, Figure 6 is a plot of au of the Interstate projects thus far completed. As in Fig, 2, the projects were approximately divided into quartiles. However due to the srnau size of' the sa:rnple in.,rolved some addi= tiona! consideration was given to the range of roughness values, By comparing Figs. 2 and 6, it becomes evident that even though some improvement in. riding quauty has been attained on Interstate highways, the degree of o.mprovement is not appreciable. Only three I<iterstate projects were smoother than the smoothest primary roads, The bulk of the projects displayed about the same riding quality as most recently constructed primary roads,

20 Removal of J.ocalized Surface Ir:reg la_ri.ties_ Regardless of whether an Interstate project proved to be of good or poor riding quality, a!!. of them apparently passed the state specifications of surface quality. On most portland cement concrete pavements this was possible only after a certain amount of localized high places were ground down to within required tolerances. The Kentucky Standard Specifications require that a 1foot straightedge be used in testing surface roughness. Any high spots indicated by a variation exceeding 1/8 inch from the straightedge are to be removed by grinding or other means. To test the effects of grinding, the southbound outer lane of project l757(4)157 was tested soon after paving and after grinding of high places was finished. This lane was selected because of its high roughness, particularly the north end of the project. The resulting roughness index of 427 before, and 421 after grinding represents about 1, 4 percent difference. This reduction in the index does not necessarily reflect the improvement made by grinding since the reliability of the roughness index, from the standpoint of reproducibility, appears to be within:!:. 2 percent. Therefore, a visual inspection of the recorded acceleration traces was made and acceleration amplitudes at ground locations were measured. 19 "

The vehicle dynamic characteristics tend to surpass the at all surprising because localized irregularities, involving a distance of ten feet, have proportionally very little effect on riding It must be concluded then that grinding produced no detectable difference in the riding quality of this pavement. This was not done, matter of fact, on the contrary. wise, the sections of pavetnent displaying the largest passenger accelerations were not the locations where most of the grinding was attributed to the deviation from previouslyrun wheel tracks. Like Only in a few instances less acceleration resulted, which could be 2
22 on roads shorter than five miles and eight sections up to ten miles in length. The three tested roads were rated as follows: The Research Division made roughness measurements of these pavements covering the full length of both lanes. The serviceability index testing calls for six 5ft., onelane sections test was made with the CHLOE profilometer which electronically totalizes a slopevariance measurement'(61nch intervals) between two closely spaced wheels pulled in the outer or inner wheel tracks. The extent of patching ; cracking and rutting constituted the structura[ failure testing. These measurements were then inserted into an equation to arrive at a serviceability index. This index rates the pavements ranging from to 5 (the larger the index, the better the pavement). Howe,ver, the testing was interrupted and discontinued after the completion of tests on US 31E, Ky. 61 and Ky. 44. The testing involved recording of roughness and structural defects on representative sections of the pavements. The roughness i additional roads were selected, US 68, Todd County, ElktonRussellville, and Ky. 61, Bullitt County, Shepherdsville,Lebanon Jet. Accordingly, sections of two primary roads, US 31E, Nelson County, BardstownHodgenville, and US 79, Todd County, RussellvilleGuthrie, and a secondary road, Ky. 44, Bullitt County, ShepherdsvilleTaylorsville, were selected for testing.

This value is presumably too low for pavements in actual service, and the present study represents an attempt to arrive at a more practical terminal value, The test sections, as rated by Kentucky's roughness index, pointed out that the 5foot sections selected were not necessarily representative, This was particularly evident on Ky. 61 where a
24 23 large difference exists between the combined roughness and the actual test section index, The Kentucky roughness index rated the pavements in the same order as the serviceability index and may, therefore, be useful as an expression of serviceability index of a pavement. An alternative would be to combine the roughness index with other parameters described the pavement structural serviceability and to meld them into an index.
25 CONCLUSIONS The completion of a number of Interstate projects has disclosed wide differences in roughness index. Between the smoothest and roughest project, a 66 percent difference in roughness was noted. However, it was possible to establish ratings for these pavements on a comparative basis. It may also be useful to arrive at some roughness index value which would describe the localized roughness qf a short pavement length, such as 3 feet. In addition, the number of individual accelerations exceeding a certain magnitude may be useq in describing or pointing out localized roughness in each project. In this study it became quite evident that the present methoq of controlling surface roughness with a 1foot straightedge fails to insure good riding quality of the pavement. Localized grinding of portland cement concrete pavements to meet the required surface tolerance produced no noticeable improvement in the roughness index. 24
