试验研究了一种具有红外热辐射功能的沥青混合料内部温度场的分布。通过在不同类型的马歇尔试件中分四层埋入温度传感器,测得在模拟太阳光照条件下混凝土各层的温度数据,验证了热辐射型沥青的降温作用,分析了不同试件各层温差曲线的变化与热蓄积量、红外辐射之间的联系。试验证明了红外热辐射型沥青混合料可有效地降低试件面层和内部的热蓄积量,从本质上预防和减少路面高温病害。
The distribution of internal temperature field of a bitumen mixture with infrared heat radiation was experimentally studied. Through the embedding of temperature sensors in four layers in different types of Marshall specimens, the temperature data of concrete layers under simulated sunlight were measured, and the cooling effect of the heat-radiated bitumen was verified. The temperature difference of different layers Changes in curve and heat accumulation, the relationship between infrared radiation. The experiment proves that the infrared heat radiation asphalt mixture can effectively reduce the heat accumulation on the surface layer and the interior of the test piece and prevent and reduce the high temperature road disease in essence.
