Asphalt pavement performance is based on several parameters and properties of the materials’ element. surface free energy that the modifier and the asphalt binder both displays. The resistance of the modified asphalt binder to stresses and moisture damage is largely determined by the bond energies. Asphalt binder qualities may be altered by either technical or natural processes, which subsequently impact on the chemical and mechanical characteristics. In addition, a correlated investigation revealed that surface free energy values may be used to assess the compatibility of a binder in relation to moisture-induced damage. Data demonstrates that the incorporation of soft clay into the asphalt binder resulted in a favorable coating and bonding capacity, as compared to the control asphalt binder. moisture-induced damage in HMA is a combined effect of loss of cohesion of asphalt binder and loss of adhesion between asphalt binder and aggregate. It was indicated that the modified binders of BPSC ratios would delay and weaken the oxidation reaction asphalt binder which can enhance the aging process. Based on absorbance peaks of carbonyl and sulfoxide bonds, the addition of BPSC would delay the aging process of asphalt binder.
