摘　　要：利用粘弹性力学理论,采用Burgers模型模拟SBR改性沥青混合料的粘弹性,通过试验研究和理论推导得到了SBR改性沥青混合料的粘弹性本构关系,并结合实例对SBR改性沥青和普通沥青的温缩应力进行了对比计算分析,直观地证明了SBR改性沥青路面良好的低温性能。The viscoelasticity constitutive relation of SBR modified asphalt mixture is obtained through experimental investigation and theoretical derivation by utilizing elasticity mechanics theory and adopting Burgers model to simulate the viscoelasticity of SBR modified asphalt mixture. Combined with the practice, contrast calculation anal- ysis on temperature contraction stress of SBR modified asphalt and common asphalt is made, directly proving good low temperature performance of SBR modified asphalt.
