Abstract

The pavement network represents a visible and expensive component of a highway agency's total transportation investment and, thus, requires proper management. Historically, the agencies managing these investments have relied on manual distress surveys carried out by personnel who drive the network and provide subjective condition assessments. Surveys completed by a highly instrumented vehicle driven at standard travel speeds have become a viable alternative. Questions regarding accuracy and consistency with existing survey protocols still remain with these automated survey methods. This paper reports on the findings from a study to evaluate automated distress surveys. Vendors and manual survey teams have evaluated the distresses along a test loop in North Carolina using two survey protocols: (1)an agency's standard network level survey, and (2)the long-term pavement performance survey. Communication between the vendor and agency is the single most important factor that allows for the proper utilization of automated surveys for network-level surveys. For best results, agencies considering using automated methods may wish to utilize an initial test loop to calibrate the automated distress results.
