Condition Rating Survey Performance Models for Pavement Treatments and Surface Types

This project will update models for Illinois Department of Transportation’s (IDOT's) Condition Rating Survey (CRS), which is used to manage, plan and prioritize transportation projects, to reflect new pavement technologies and preservation treatments developed over the past 10 years. The researchers will also develop Illinois-specific performance models for nationwide Federal Highway Administration pavement indices, including International Roughness Index, rutting, faulting, and percent cracking, for all IDOT pavement types. They will also create software that will allow IDOT to model pavement deterioration and update the models as needed. The updated CRS models will improve the accuracy of IDOT’s CRS calculations that forecast future pavement condition as well as projections of FHWA’s performance metrics for Illinois, which will help to identify gaps in performance and potential funding needed to close those gaps.
