What is Pavement Service Life Analysis: AASHTO vs M-E about?

This study evaluates the service life of pavement rehabilitation designs using the AASHTO 1972 and Mechanistic-Empirical (M-E) pavement design guides. It finds that the M-E method generally predicts a longer service life with lower variation compared to the AASHTO 1972 method, which is influenced by structural number differences and location. The research aims to understand the differences in estimated service lives and the factors contributing to these differences rather than determining which method is su
