排水性沥青路面降温性与效果分析

目前沥青路面车辙病害现象严重,为了降低车辙的严重程度,对车辙产生的原因作详细论述,并提出沥青路面降温的必要性及关键面层。针对各面层降温的程度不同,因此在国内比较早地在各面层中埋设温度传感器,监测中面层及下面层温度,对不同面层进行温度比较分析。结果表明,排水性沥青路面对中面层和下面层的降温程度均比SMA路面高。中面层降温效果的显著将有助于节约修筑道路的资金,降低修筑成本。

The Thermal Reduction property and Effect of Porous Asphalt Pavement

This paper reviewed the causes of asphalt pavement rutting,and pointed out the necessary of pavement thermal reduction research.The thermal sensors were settled in- to the pavement to survey the thermal reduction of different type asphalt mixture used in middle and binder courses.The results show that porous asphalt pavement's thermal re- duction is better than the SMA pavement.Using this middle course can decrease rutting and save cost.
