Title: Improving the Long-Term Condition of Pavements in Massachusetts and Determining Return on Investment: Implementing the AASHTO Mechanistic-Empirical Pavement Design Guide— PHASE II
Date: September 2022
Status: Completed
Summary: The goal of this study was to develop an AASHTOWare® Pavement M-E user’s manual and develop a local experimental plan and sampling template for Massachusetts. A stand-alone software manual was developed that provides a thorough step-by-step procedure on how to use the software. The manual guides users on how to generate the data, in particular, material properties and climatic and traffic data as they relate to local locations within the state of Massachusetts. A preliminary experimental and sampling plan for local verification/calibration of the distress functions and smoothness regression equations in the AASHTOWare® Pavement Mechanistic-Empirical Design was also developed. Finally, testing was conducted on typical plant-produced mixtures sampled from across Massachusetts in an attempt to accelerate future phases of this research. This report outlines the work conducted in phase two of a four phase larger research project aimed at implementing the AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) in Massachusetts.
