Calibration of the Mechanistic-Empirical Pavement Design Guide for Local Paved Roads in Wyoming.

摘要

Since release of the MEPDG in 2004, many national and state agencies have been working toward implementation of the new pavement design guide through calibration and validation. In order to aide Wyoming’s Department of Transportation in its push toward total implementation, this study developed a set of traffic distributions and calibration coefficients for use within the MEPDG on designs of local paved roads that experience heavy truck traffic associated with the energy industry. A sensitivity analysis was also performed during this study to determine the effect of varying layer thicknesses on the prediction capabilities of the MEPDG. Findings of this report can be implemented on local paved roads that experience heavy truck traffic associated with the oil and gas industry.
