ABSTRACT
While there are multiple methods available for identification of pavement cracking data, these methods and cracking data are not always compatible, possibly complicating the sharing of cracking data information among agencies and vendors as well as reporting of such data to the US Federal Highway Administration (FHWA) to establish national, state, and local performance goals. In this study, comprehensive reviews on existing federal and state highway agencies’ cracking data collection practices were conducted, including how data are collected and classified. Current practices adopted by each agency have also been compared to interim standardization protocols, building upon work reported in American Association of State Highway and Transportation Officials (AASHTO), PP 67, “Quantifying Cracks in Asphalt Pavement Surfaces from Collected Images Utilizing Automated Methods”, and PP 68, “Collecting Images of Pavement Surfaces for Distress Detection”. The study’s findings are summarized in the context of developing standard definitions for comparable pavement cracking data.
