This studyis concerned with the constitutive modeling of asphalt concrete mixtures. The constitutive model derived is based on a thermodynamic framework that recognizes the fact that materials can exist in multiple stress free states. We derive the constitutive relations byassuming that asphalt concrete is a constrained two constituent mixture of asphalt mastic and aggregate matrix. Assumptions are made concerning the manner in which the bodystores and dissipates energyand the constitutive relations for the stress is deduced from such an assumption. The triaxial and stress relaxation tests conducted byMonismith and Secor [Viscoelastic behavior of asphalt concrete pavements. Report, Institute of Transportation and Traffic Engineering, Universityof California, Berkeley, 1962] are used as benchmarks to delineate the efficacyof the model in predicting the mechanical response characteristics of asphalt concrete over a wide range of temperatures and confining pressures.
