Abstract: Pavement rating is a necessary and labor-intensive job and one with a high turnover rate of personnel. Also, rating scores are often inconsistent from day to day, or between different raters. A system is described that is able to solve both of these problems associated with pavement rating. The system and its operators fit into a van. Three electronic sensors and associated optical equipment scan a strip of highway across one pavement lane. The system can automatically recognize different types of pavement distress. The concept has been shown to work in the laboratory.
