Abstract

Three types of aging methods were conducted on rubber powder modified asphalt, and the basic physical properties test, dynamic shear rheological test and infrared spectrum analysis were adopted to study the effect of aging methods on properties of rubber powder modified asphalt comprehensively. Results show that effects of different aging methods on physical properties of rubber powder modified asphalt are inconsistent. There is a slight influence of aging on its rheological properties, which means a better aging resistance. Through microanalysis, it can be found that there is a significant aging for rubber powder modified asphalt after pressurized aging, followed by the ultraviolet aging. The aging degree of rubber powder modified asphalt is relatively small after short-term thermal-oxidative aging.
