Abstract:Accurate joint transverse faulting prediction is essential for proper pavement design. Departments of transportation are encouraged to evaluate, recalibrate, and even modify the faulting model if discrepancies between predicted and field measured faulting are observed. The Pennsylvania Department of Transportation (PennDOT) identified a series of problems with Pavement ME faulting prediction for jointed plain concrete pavements (JPCP). Moreover, the current design of bonded concrete overlays on asphalt (BCOA) lacks a faulting model that simulates the different aspects of the BCOA structure. To address these issues, this project had two main objectives: reevaluate and modify Pavement ME faulting model for JPCP and develop a singular faulting model for BCOA.
