FORCE DUCTILITY -- AN ASPHALT PERFORMANCE INDICATOR

Highway pavements, like any structures expand and contract with changes in temperature and they experience stresses and strains under traffic loadings. If a pavement material cannot withstand these forces or if unusually high forces are generated for a certain material, fracture of the structure occurs. This inevitably results in accelerated pavement deterioration. The Force Ductility test is based on the theory that an asphalt must be able to relax under the applied loads, but possess enough tenacity to maintain a proper matrix. The higher the stress level in the thin film of asphalt between the aggregate, the greater the change for fracture. The paper develops the theory and background of this modified ductility test and attempts to establish a reasonable case for its routine use in asphalt testing.
