沥青胶浆的低温性能试验研究

Test studying of asphalt mortar's performance at low temperature

笔者在文中采用自制的沥青胶浆蠕变测定仪,通过研究确定了试验条件和方法,对不同粉胶比(DP)沥青胶浆的低温蠕变性能进行了试验研究.此外还分析了影响沥青胶浆低温变形的因素,指出在选择合理粉胶比时,除了考虑所用沥青品种、标号以及矿粉外,还应该和沥青胶浆低温性质结合起来.

This paper prepared different DP asphalt mortar with creeping test instrument which made by ourselves, then determined testing condition and methods. We studied their creeping performance at low temperature. We also studied the influencing factors to the deformation of asphalt mortar and pointed out that it must combined the quality grade, brand of asphalt and mineral powder as well as other factors to select the reasonable DP.
