Condition rating survey manual : state system condition rating survey (CRS).

The Illinois Department of Transportation (IDOT), through the Office of Planning and Programming (OPP), conducts a Condition Rating Survey (CRS) to assess pavement condition on its approximate 16,000 mile state highway system. The CRS is an important tool to assist the Department with its pavement management activities. A CRS value indicates the current condition of a pavement. CRS is a factor in highway program development, provides an opportunity to review the highway network, provides overall condition of the state highway system, gives input into the legislative/budgeting process and allows calculation of pavement needs.
