IMPROVED PREDICTION MODELS FOR PCC PAVEMENT PERFORMANCE - RELATED SPECIFICATIONS

Performance-related specifications (PRS) for the acceptance of newly constructed jointed plain concrete pavements (JPCP) have been developed over the past decade. The main objectives of this study were to improve the distress and smoothness prediction models used in the current PRS approach for JPCP, and to provide guidelines for calibrating these models for local conditions. Both the improved prediction models and the calibration procedure were implemented in the PaveSpec 3.0 PRS software. The project team enhanced existing models for predicting: transverse joint faulting; transverse fatigue cracking; transverse joint spalling; International Roughness Index (IRI); and initial IRI as a function of initial Profile Index (PI). This TechBrief describes the improved performance models and provides an example application of the improved models. Comments are also included on the calibration of the prediction models and on the PaveSpec PRS software.
