A Study on Road Performance of Pave-Strong Additive

PS(Pave-Strong) additive is a new compound polymer,which will be specially used as modified additive to modify an asphalt mixture.By carrying out the rutting test for AC-13C asphalt mixture,the high temperature stability of mixtures added with different doses of PS additive is mainly studied,and compared with another 4 types of asphalt mixtures(non-modified,and modified by SBS,Sasobit and PLAST.S).The experimental results indicate that PS additive can effectively improve the high temperature stability of asphalt mixture,and provide a better performance-price ratio and a better operability vis-a-vis the SBS,Sasobit,PLAST.S modified method.All this presents a fine prospect of PS application.
