Rsearch Development of Modified Asphalt

More materials,as modifier,are used to improve the properties of modified asphalt.Besides,the new evaluation standards and methods,new chemical analysis methods are used to evaluate the properties more completely and accurately.The situation and development of modified asphalt research at home and abroad are summarized.From the aspcts of modification mechanism,influencing factors and evaluation methods,various modified asphalts are introduced,and the development trend of modified asphalt technology is illustrated in the paper.
