Using surface free energy to evaluate the fracture performance of asphalt binders
Department of Civil and Environmental Engineering
Surface free energy has been mainly employed to determine the adhesive bond energy for the evaluation of moisture resistance between binder and aggregate, but its association with binder fracture resistance has not been fully explored yet. Surface free energy was successfully measured for five binders by using sessile drop method. The Double-Edge Notched Tensile and Binder Fracture Energy tests were used to establish the correlation between binder fracture parameters and surface free energy. Correlation results indicated that surface free energy is a good indicator for binder fracture performance.
