Pavement Detailed Distress Index Calculations

The calculations of the index for the Distress condition category are based on the data methods and described in the U.S. Army Corps of Engineers Pavement Maintenance Management System and ASTM D-6433-11 Standard Practice for Roads and Parking Lots Pavement Condition Index Surveys.

For each distress record the deduct points are determined. The contents of the extent and severity fields are interpolated with the deduct points table for that distress. Distress information is stored in the Distresses library.
