The SBR modified emulsified bitumen does for the highway under the sealing course,the tacky surface,was prompted forward the emulsified bitumen application step.

The SBR modified asphalt which has good low temperature property is widely used for high grade road paving.

The changes of cleavage strength of SBR modified asphalt mixture and base asphalt mixture can reflect the rule that the asphalt mixture changes with time by using ultraviolet aging at different time.

In this paper, the pavement performance of SBR modified asphalt, especially in the fields of low temperature ductility, cracking resistance and aging resistance after these comparative tests parameters were analyzed between Kin Shi SBR modified asphalt and native produced high quality asphalt .

Performance of nano-calcium carbonate and SBS compound modified asphalt;

Experimental study on compound modified asphalt by SBS and crumb rubber

With various evaluation methods and indexes,road performances such as stability in high temperature and in low temperature,thermal storage etc for a new type of composite modified asphalt have been studied and evaluated,and the tested results have been compared and analyzed.
