The Arkansas State Highway and Transportation Department (AHTD) contracted the University of Arkansas to conduct a network crack survey of a large portion of its non-interstate National Highway System (NHS) and develop a cracking protocol to be used by AHTD. The Digital Highway Data Vehicle (DHDV) was used to acquire high-resolution digital images and analyze cracks with the automated real-time Distress Analyzer. This paper presents a preliminary study using the DHDV and the Distress Analyzer for data analysis on a network of about 100 miles of pavements as well as the study conducted on 25 miles of the surveyed pavements to generate the cracking protocol for AHTD. In addition, a manual survey was conducted on the same network of pavements. The data analysis with the Distress Analyzer covers the entire network, while the manual survey covers 5% of the same area on a mile-by-mile basis. For developing the cracking protocol for AHTD, a manual survey was performed on 10% of each mile in a 25-mile section of pavement based on AASHTO PP44-00, Standard Practice for Quantifying Cracks in Asphalt Pavement Surface.
