Evaluation and Validation of a High-speed Multi- Function System for Automated Pavement Condition Survey

Manual surveys still represent the most widely used means for inspecting and evaluating pavements. Manual rating of pavements through windshield surveys to identify the types of surface cracking and other distresses leads to relatively slow evaluation. Furthermore, the survey crew must sometimes physically be in the travel lane to evaluate the pavement, exposing themselves to hazardous conditions. Conversely, high speed automatic pavement evaluation is an efficient and cost-effective alternative that assures the safety of the field survey personnel and the traveling public.
