Road Science: M-E PDG Improves the Art of Road Design by Adding Material Science to the Mix

The American Association of State Highway and Transportation Officials' (AASHTO's) Interim Mechanistic-Empirical Pavement Design Guide (MEPDG) and its implications for state and local road design are discussed by the author. AASHTO's traditional road design concept was developed in the 1950s and has undergone changes since. The MEPDG, which replaces arbitrary extrapolation with science and makes roadway design more realistic, was approved by AASHTO in 2008 as an official interim design procedure. Adoption of the Interim MEPDG by the Missouri Department of Transportation is used to illustrate MEPDG applications.
