- W2391178233 abstract "To improve the pavement performance and durability of stone matrix asphalt( SMA),styrene-butadiene triblock copolymer( SBS),rubber powder,tackifying resin and plasticizer were used to modify the asphalt,and the high viscosity and high elastic modified asphalt was developed. The pavement performance and durability of SMA was analyzed comparatively when using high viscosity,high elastic modified asphalt,high viscosity asphalt and SBS modified asphalt as binder respectively. The results show that the high temperature viscosity and the elastic recovery of asphalt are closely related to the dosage of rubber powder; the viscoelasticity of high viscosity and high elastic modified asphalt is excellent,whose softening point is 92 ℃ and recovery of elasticity at 5℃ is 86%,viscosity at 60 ℃ reaching 62 000 Pa·s; the pavement performance and durability of SMA is improved,finally the dynamic stability of which at 70 ℃ exceeds 7 000 times·mm- 1,and fatigue life stress ratio at 0. 3 of which exceeds sixty thousand times." @default.
