Experimental Research on Road Performance of Natural Asphalt Modified Asphalt Mixtures

Abstract:

This report mainly evaluated the pavement performance of natural asphalt from Albania. Firstly, base asphalts were processed with natural asphalt by “wet method” modification technique to obtain modified asphalt; and mixture are produced with these modified asphalt binders, and then high temperature performance and moisture stability properties are evaluated by some standard methods. Analysis shows that this natural asphalt can remarkably improve the high temperature and moisture stabilities of asphalt mixture, and own cost-effective advantage.
