Title:Update of Condition Rating Survey (CRS) Calculation/Prediction Models Phase 3. CRS Prediction Model Development
Author(s):Heckel, Laura; Ouyang, Yanfeng
Subject(s):CRS, prediction models, deduct values
Abstract:The Illinois Department of Transportation (IDOT) determines a Condition Rating Survey (CRS) value for each roadway section using CRS calculation models. After the rating values have been determined, IDOT uses prediction models to estimate the condition of the pavements in the future. The objective of Phase 3 was to revise the existing prediction models and develop new models for pavement types that currently have none. Models were created or revised for 28 pavement types. Both D-cracking and the use of SMART (thin overlays) are known to reduce the expected life of pavements. Therefore, D-cracking and SMART models were created whenever possible.
