Studies the Key-Technologies of Karamay Matrix Asphalt Used in SBS Modified Bitumen

Ou, Zu Min / Li, Fu Jian

This paper studied the performance of SBS modified Karamay asphalt and asphalt mixtures for the purpose of widely applies it to Xinjiang highway. The effects of the different compositions of equal density modifier on modified asphalt and the compatibility of the matrix asphalt with its modifier were investigated by adjusting the content of reclaimed rubber and SBS polymer. Experiment results indicate that modified asphalt has the best performance when the modifier particles consist of 48.6% SBS polymer, 43.2% reclaimed rubber and 8.2% adjuvant. It is shown that the applying of modifier particles can improve the performance of Karamay modified asphalt and HMA (Hot Mix Asphalt) dramatically.
