Research progress in crumb rubber modified asphalt

The condition and application of crumb rubber modified asphalt domestic and abroad were introduced, and the characteristic, mechanism, preparing method, storing stability and temperature susceptibility of the crumb rubber modified asphalt were analyzed. It was pointed out that the application of crumb rubber in asphalt modification can not only improve the performances of bitumen and promote the reuse of used rubber and decrease environment pollution as well. So the crumb rubber modified asphalt has good applied foreground. The industry criterion of the crumb rubber modified asphalt should be established in our country promptly.
