对高粘沥青掺加两种类型温拌剂后的粘度等沥青指标进行研究,并对掺加温拌剂后沥青混合料的路用性能进行研究。结果表明:在高粘沥青中掺加3%Sasobit与掺加8%的沸石粉,均能将高粘沥青的施工温度降低15℃左右,3%Sasobit与8%沸石粉的降粘效果相当;温拌剂对多孔性沥青混合料性能的影响主要在低温性能方面,对其他性能基本无影响。
The viscosities and other asphalt indexes of high viscosity asphalt blended with two types of warm mix were studied, and the road performance of asphalt mixture after mixed with warm mix agent was studied. The results showed that the addition of 3% Sasobit and 8% zeolite powder in high - viscosity bitumen could reduce the construction temperature of high - viscosity bitumen by about 15 ℃, and the effect of 3% Sasobit was equivalent to that of 8% zeolite powder. The effect of warm mix agent on the performance of porous asphalt mixture mainly has no effect on other properties in low temperature performance.
