Microdamage Healing in Asphalt and Asphalt Concrete, Volume 3: A Micromechanics Fracture and Healing Model for Asphalt Concrete

R. L. Lytton / C. W. Chen / D. N. Little

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 pseudo strain energy as loading are applied to the samples and as damage occurs and mixture properties including crack length changes upon loading and mixture cohesive surface energies.
