Study on Preparation and Properties of SBS Modified Asphalt
In order to investigate the performance differences of SBS modified asphalt,the paper conducted experimental studies on the peel strength,low temperature flexibility and high temperature performance of SBS modified asphalt mixtures with SBS content of 5%,10%,15%and 20%.The results show that SBS4402 modifier has the best improvement effect on modified asphalt,LG501S modifier and LG412S modifier have the second effect,respectively.The low temperature flexible modification effect of LG501S is the best,followed by SBS4402 and LG412S.LG501S modifier has the best improvement effect on peel strength,followed by SBS4402 modifier,LG412S modifier has the weakest improvement effect.
