Incorporation of Joint Faulting Model into BCOA-ME

This project will expand the climate stations being incorporated into the new faulting model for the Bonded Concrete Overlays on Asphalt (BCOA)-ME design procedure.It will perform Enhanced Integrated Climatic Model (EICM) analyses for the conditions defined in the experiment to determine the temporal temperature profiles in the overlay and the mid-depth asphalt temperature. A database will be populated with calculated parameters and their respective pavement structure and geographical information. Equations will be developed so that an equivalent effective linear temperature gradient and an effective asphalt temperature can be predicted based on the pavement structure and the geographical location. A validation process will be performed to ensure the trends of the predictions are accurate. Finally, implementation will consist of programming the prediction equations into the BCOA-ME web application such that they are able to interact with the faulting model. The validity of the program will then be checked by performing a sensitivity analysis and comparing observed performance with that of the predicted performance for various climatic conditions in National Road Research Alliance member states.
