Applied Research of the Modifying Agent of Rubber Plastic Composite (MaR) in Asphalt Mixture

Article Preview

Abstract:

70# and 90# matrix asphalt mixture with MaR were studied through dynamic modulus test, rutting test, freeze-thaw splitting test, bending test to study the applicability of the Modifying agent of rubber plastic compound (MaR) in matrix asphalt mixture.Test results were Compared with SBSI-C modified asphalt mixture.The results indicate that: high-temperature stability of MaR+70# asphalt mixture is as well as SBSI-C modified asphalt mixture,and is bettere than MaR+90# asphalt mixture; water stability of MaR+90# asphalt mixture is bettere than SBSI-C modified asphalt mixture and MaR+70# asphalt mixture; low temperature performance of MaR+90# asphalt mixture is bettere than MaR+70# asphalt mixture, but is worse than modified asphalt mixture SBSI-C ; MaR+70# asphalt mixture can be first used in area of resisting high temperature and rutting, MaR+90# asphalt mixture can be used if the water stability performance and low temperature performance are considered.
