| Abstract | Volume 3 documents the development of a micromechanics fracture and healing model for asphalt concrete. This model can be used to calculate the density and growth of microcracks during repeated direct tensile controlled-strain loading. The model is based on a relationship among stiffness changes in the mixture as damage occurs, the rate of change in dissipated crack length changes upon loading and mixture cohesive surface energies. |
