Abstract

Roadway maintenance management systems and pavement management systems are growing in popularity with road maintenance agencies. These systems require an objective evaluation of roadway pavement conditions, including a numerical rating scale to be used in analysis and priority selection procedures. An evaluation and rating system for gravel roads has been developed. The evaluation and rating give primary consideration to drainage, crown, and adequacy of the gravel thickness. Other measures of distress, such as washboarding, dust, ruts, and potholes, are also considered; however, they are considered as secondary indicators of roadway conditions. The procedure highlights an understanding of typical distress along with the causes and remedies for the individual types of distress. The rating procedure is closely linked to the appropriate maintenance or rehabilitation treatment.
