The study evaluates available pavement distress surveillance equipment and recommends a system of proven value to the Arkansas State Highway and Transportation Department. The requirements of the system are that it be able to provide summary data for pavement management purposes; in such form as to be capable of multiple interpretations and uses; economically adaptable to future innovations and state-of-the-art developments. Three equipment systems, ARAN, PASCO-RR, and Laser RST, were demonstrated and after evaluation were found to meet these requirements. ARAN and Laser RST are the most automated providing all significant data except cracking and faulting objectively. PASCO-RR is the least automated providing only rut depth summaries and longitudinal profile with all other data requiring considerable manual and subjective processes. Classification and quantification of cracking and detection of faulting is a visual subjective process in all systems. ARAN is the most compatible with future developments. Laser RST would require the addition of some sort of image acquisition device. PASCO-RR is not compatible.
