NONLINEAR VISCOELASTIC PROPERTIES OF BITUMINOUS CONCRETES

Viscoelastic properties of bituminous concretes have been studied by observing creep behavior under a large range of compressive stress levels and temperatures. Effect of air void content on the creep properties has been observed. Results indicate that the test materials display linear viscoelastic properties only at low stress levels and temperatures. The nonlinear creep behavior that is found to occur at higher stress levels and temperature has been characterized by the nonlinear viscoelasticity theory and the creep compliance functions based upon this theory were evaluated for the test materials. It is found that an increase in air void ratio leads to higher creep strains for a given stress level.
