RESEARCH ON THE PERFORMANCE OF RESIN RUBBER MODIFIED ASPHALT PAVEMENT
In order to improve the performance of the highway and to ensure the traffic safety,we improve the prop-erties of asphalt mixture,in which the petroleum asphalt is used as the raw material,and the resin rubber modified asphalt slurry is prepared by adding different proportions of styrene-butadiene rubber and phenolic resin to the raw materials.The optimal content of phenolic resin and styrene-butadiene rubber is determined to be 3%and 4%re-spectively through the penetration degree,softening point,elastic recovery,and Brinell viscosity testing.The results show that the incorporation of phenolic resin into styrene-butadiene rubber modified asphalt mortar improve the high-temperature performance of styrene-butadiene rubber modified asphalt under the premise of ensuring the low-temperature performance of styrene-butadiene rubber modified asphalt.
