1 3-D Laser Data Collection and Analysis of Road Surface Texture Humaira Zahir, Mustaque Hossain, Rick Miller ROAD PROFILE USERS GROUP MEETING, 2015 RALEIGH, NC
2 Presentation Organization - Introduction - Problem Statement - Objective - Tests Performed - Results and Discussions - Conclusions
3 Introduction - Good pavement condition is an essential prerequisite for a safer highway - Road surface friction minimizes skidding and reduces roadway crashes - Skid resistance highly depends on the pavement texture characteristics - Estimation of texture characteristics could give useful information about the condition of the roadway
4 Problem Statement - ASTM Locked Wheel Skid Trailer (LWST) is universally used for determining friction characteristics - LWST measures pavement skid number - Driving speed should be 40 mile/hour or 55 mile/hour - Maintaining speed is difficult especially on some curves and ramps
5 Problem Statement - 3-D Laser Crack Measurement System (LCMS) can be a viable alternative to LWST in some locations - LCMS measures Mean Texture Depth (MTD) of pavements - LCMS offered the possibility to measure pavement texture more precisely
6 Objectives - To assess whether skid resistance on different KDOT highways can be assessed using LCMS measurements - To find a suitable correlation between skid number and texture depth - To replace the traditional ASTM skid trailer by LCMS for routine skid monitoring
7 Test Sections Four KDOT (Kansas Department of Transportation) Highways were selected for investigation - K-18 Westbound/ I-70 Westbound On-Ramp (Geary County) - K-177 Southbound/ I-70 Westbound On-Ramp (Geary County) - I-70 Westbound Off-Ramp/ K-177 Northbound (Geary County) - K-87 (North of K-9, Nemaha County)
8 Equipment used for Data Collection Pavement friction and texture data were collected using four different instruments: - ASTM Locked Wheel Skid Trailer (LWST) - 3-D Laser Crack Measurement System (LCMS) - Circular Texture Meter (CTM) - Dynamic Friction Tester (DFT)
9 Locked Wheel Skid Trailer - Measures steady state friction force - A locked wheel is dragged under constant load at a constant speed over a wet pavement - Friction is determined from resulting force and reported as Skid Number (SN) - Higher SN represents greater skid resistance
10 Locked Wheel Skid Trailer - Ribbed and Smooth tires are used for measuring friction - Operated at near highway speed - Can measure large sections of roadway without lane closures
11 Laser Crack Measurement System - Use of high speed camera, custom optics and laser line projectors - Acquire both 2-D images and high-resolution 3-D profiles of the road - Can be operated under all types of lighting condition - Various pavement types can be measured at survey speed - Data analysis software analyze all collected data
12 KDOT Laser Crack Measurement System
13 Circular Texture Meter - Laser-based device for measuring Mean Profile Depth (MPD) at a static location - There is a Charged Couple Device (CCD) laser sensor in the bottom of the instrument
14 Circular Texture Meter (CTM) - Measures the profile of a circle having inch circumference - Divides the circumference into eight segments - Average Mean Profile Depth (MPD) is determined for each of the segments - Reported MPD is the average of all eight segment depths
15 Dynamic Friction Tester (DFT) - Measures frictional characteristics of roadway - For Friction Number (FN) calculation, needs to put over the same area where CT Meter measurement was taken -The disk at the bottom of the machine consists of 3 rubber slider
16 Dynamic Friction Tester - During rotation, the disk measures the torque generated - Torque is monitored and recorded at 20,40, 60 and 80 km/hr - Both CT meter and DF tester readings are required to calculate the Friction Number

34 Conclusions -We are still evaluating using the LCMS data (MTDs) to determine if surface friction (based on texture) is adequate. -We continue to compare texture depth and µ values to the SNs and MTDs that we are already collecting. -We will still collect locked wheel skid data and LCMS (MTDs) while we learn if/how we can be more efficient in our collection. - More roadway surface characteristics need to be analyzed to develop a valid correlation between MTD and SN
