AASHTO Layer Coefficients for Bituminous Materials
This report presents the results of a study to derive structural layer coefficient of several Mississippi Department of transportation (MDOT) hot mix asphalt (HMA) mixtures. The materials include surface, binder and base mixtures, and high type surface, binder and base mixtures. Two Special Provision asphalt treated premeable materials (ATMPs)--Special Provision Mix 907-306-1 and 907-306-2-are also investigated. Pavement performance is the criterion employed in deriving the structural layer coefficient. A prediction model is developed to assess the performance and, thereby, fatigue life, treating traffic, material characteristics, and environmental effects as stochastic variables. Making use of this model, with the stipulation that fatigue cracking be less than 45 percent, equivalent pavement cross sections are established. Layer equivalency of various materials is derived by comparing the equivalent cross sections. The resulting layer coefficients of surface, binder and base mixture are, for the most part, in agreement with those proposed by AASHTO Committee on Design.
