AASHTO publishes new pavement design guide

The American Association of State Highway and Transportation Officials (AASHTO) released a new edition of its pavement design guide “Mechanistic-Empirical Pavement Design Guide: A Manual of Practice, 3rd Edition.”

Developed by the AASHTO Committee on Materials and Pavements, this guide describes the pavement design methodology termed mechanistic-empirical (M-E) pavement design. Based on engineering mechanics that have been validated through extensive road test performance data, the guide presents information necessary for pavement design engineers to use the M-E design and analysis method.

This new 2020 third edition includes several revisions and updates and is available here.

The American Association of State Highway and Transportation Officials (AASHTO) is a nonprofit, nonpartisan association representing highway and transportation departments in the 50 states, the District of Columbia, and Puerto Rico.
