沥青混凝土隔热性能现场测试与研究

Field Test and Laboratory Performance Test of Thermal Insulation Asphalt Concrete

为缓解沥青路面的高温车辙病害,优选多种原材料,制备了具备隔热降温属性的沥青混凝土路面材料。在此基础上,在隔热沥青混凝土试验段进行光栅式温度传感器布置和埋设,系统测试和评价了隔热沥青混凝土的隔热降温功效及各项路用性能。试验结果表明:隔热沥青混凝土具有良好的隔热降温性能,在实际工程中取得了良好的应用效果。

For the purpose of mitigating the high temperature disease of asphalt pavement,a few kinds of raw materials were selected,and thermal insulation asphalt concrete was prepared.The thermal insulation performance was studied systematically through using climate resistance test machine.The grating temperature sensor was buried into the experimental pavement of thermal insulation asphalt concrete.The thermal insulation performance and road performance were tested and evaluated in the field.The results showed that thermal insulation asphalt concrete had good thermal insulation performance and was well performed in the engineering application.
