ESSENTIAL AND PLASTIC WORKS OF DUCTILE FRACTURE IN ASPHALT BINDERS

摘要: Currently, no satisfactory asphalt binder test method exists that can relate properties measured in the laboratory to fatigue performance service. The loss modulus of binder, G*sinδ, as proposed by Strategic Highway Research Program, is a rheological parameter measures energy dissipated within homogeneous at low strains under dynamic conditions. A number publications have reported this provides little correlation with susceptibility concrete fracture high nonlinear regime simulated in-service essential work method, an energy-based testing approach used for characterization ductile materials, was explored. Given material ambient temperatures, it only reasonable assume yields valuable information likely use ranking. binders investigated showed wide r...
