The Distresses library data is based on the U.S. Army Corps of Engineers Pavement Maintenance Management System. Use this library of data to view the information and illustrations for detailed distress inspections.
The calculations for the distress condition category and pavement/pavement area OCI are based on the data and methods described in the U.S. Army Corps of Engineers Pavement Maintenance Management System.
The Pavement or Pavement Area Length and Pavement/Pavement Area Width must be populated to calculate the distress index.
The data entered represents the percent of the sample affected by the distress:
For example, if you have a distress of Rutting Affects for 250 ft2 of a 1000 ft2 sample. This represents 25 percent of the sample. This calculates the portion of the sample affected by the distress and enters that value—in this case 250/1000 or 25 for 25 percent.
