Calibration of Rutting Models for HMA Structural and Mix Design

Principal Investigator(s) 

The accuracy of permanent deformation (rutting) prediction models for flexible pavements depends on effective calibration and validation with robust data sets. This project will enhance the hot-mix asphalt rutting prediction model in the new national mechanistic-empirical pavement design methodology developed in NCHRP Project 1-37A. The enhanced rutting model will be calibrated and validated using measured materials properties and pavement performance data from a large set of in-service field sections and full-scale test sections.
