【摘要】 改性沥青是一种典型的流变性材料，在荷载作用下会产生流动。本研究采用力学模式比较清晰的滑板低温测粘试验方法测定了改性沥青的低温粘度，并采用实测的低温粘度以及由此得到的感温性来说明改性沥青的低温性能，结果更接近实际情况。更多还原

【Abstract】 The modified asphalt is a kind of rheo-deformation material,on action of the load,it will fluidifyIn this paper,by means of viscosimetry with sliding-plate viscometer,which has a more distinct mechanic model,the low temperature viscosity of modified asphalt is determined.Using this kind of test method can demonstrate the low temperature performance of asphalt,the result is more accessible to the actual conditions更多还原
