| Abstract: | Two modified asphalts were made from Huanxiling AH-90,Japan AH-110 and 6% of Yanshan SBS-2 separately.Their penetration indexes,softening points,ductilities,elasticities and aging properties were improved.We advise that the best quantity of SBS-2 is 4%~6% and 4%~5% for heavy traffic paving asphalt made in our country and imported asphalt separately. |
