Evaluation of the Laser Road Surface Tester for Use as a Production Condition Survey System in Florida (Pavement Condition Survey Laser Equipment Evaluation)

摘要

The report summarizes the findings when comparing the Department's 1987 Pavement Condition Survey data to that of the Infrastructure Management Services for data collected within the Second District. The report compares ride data collected with the Department's Mays Ride Meters to that collected using the Infrastructure Management Services' Laser System. Comparisons are also made between rut depth taken with a six foot straightedge and rut depth as measured with the laser system. Finally, a comparison between a subjective cracking measurement and cracking from the laser unit are compared. The data compared consisted of 1206 sections of flexible pavement and 70 sections of rigid pavements. Results and analyses of the test data are presented.
