摘要：	The development and use of a nonlinear elastic, viscous with damage model are discussed. The model is proposed as a constitutive relation for asphalt concrete mixes to permit prediction of permanent deformation. The model is intended to capture the macrobehavior of mixes, including (a) the dilatancy observed when the mix is subjected to shear strains, (b) the increase of effective shear modulus under increased hydrostatic pressure, (c) the significant variation of behavior with changes in temperature and rates of loading, and (d) the residual accumulation of permanent deformation under repetitive loading. This model has been developed as part of the Strategic Highway Research Program A-003A efforts to characterize the permanent deformation characteristics of asphalt-aggregate mixes. A new series of tests proposed for the determination of the material properties is presented; modeled and observed responses from a simple validation test are compared; and the use of the model to predict permanent deformation response in an asphalt concrete pavement section is illustrated.
