Independent Review of the Recommended Mechanistic-Empirical Design Guide and Software

At the request of the AASHTO Joint Task Force on Pavements (JTFP), NCHRP initiated Project 1-37A in 1996 to develop a guide for the design of new and rehabilitated pavement structures. In contrast to the current AASHTO Guide for Design of Pavement Structures, the guide recommended in 2004 by the Project 1-37A research team is based on mechanistic-empirical (M-E) principles; provides a uniform basis for the design of flexible, rigid, and composite pavements; and employs common design parameters for traffic, subgrade, environment, and reliability. A key component of the JTFP's plan for implementation and adoption of the M-E pavement design guide and software is an independent, third-party review to test the design guide's underlying assumptions, evaluate its engineering reasonableness and design reliability, and identify opportunities for its implementation in day-to-day design production work. The objective of this research project is to conduct an independent engineering review of the mechanistic-empirical pavement design guide and software developed in NCHRP Project 1-37A.
