Survey
A web-based survey was emailed to state DOT pavement design engineers during
February 2008. Responses were received from 34 state agencies; 11 of which have experience
designing composite pavement structures.
Mechanistic and Mechanistic-Empirical Evaluation
Mechanistic analysis of various composite pavement structures was performed using
software assuming both non-linear and linear-elastic pavement behavior. The software allowed
for the pavement behavior to be analyzed. In addition, empirical-based deterioration models
were used to assess the anticipated condition of the analyzed structures.
