摘要

The formulation of constitutive equations for asphaltic pavement is based on rheological models which include the asphalt mixture, additives, and the bitumen. In terms of the asphalt, the rheology addresses the flow and permanent deformation in time, under different temperatures, and under different loading conditions. Currently, there are various laboratory methods used to determine the rheological parameters of the asphalt. Unfortunately, most of these test are conducted in the linear viscoelastic region, therefore the true picture of asphalt during in-service has not been fully investigated. Furthermore there are quite few polymer-modified asphalts that have been used. The mathematical models needed to formulate and model these materials are limited. This study attempt to develop a mathematical approach to modeling of polymer modified asphalt which is applicable in pavement design.
