Cooling asphalt pavement structure and construction method thereof
The invention discloses a cooling asphalt pavement structure and a construction method thereof. The cooling asphalt pavement structure comprises an asphalt surface layer, and heat conducting rods are uniformly inserted into the asphalt surface layer; the asphalt surface layer comprises a lower surface layer, a middle surface layer and an upper surface layer which are sequentially laid from bottom to top; the upper surface layer is formed by paving a thermal resistance asphalt mixture, and the heat conduction rods are vertically embedded into the lower surface layer, the middle surface layer and the upper surface layer; according to the invention, the heat conduction rods are uniformly inserted into the asphalt surface layer, and the upper surface layer is formed by paving a thermal resistance asphalt mixture; through heat resistance of the upper surface layer and heat conduction of the heat conduction rods, the temperature of the asphalt pavement is effectively reduced, and the temperature gradient is reduced; and meanwhile, the heat conduction rods can play a role of a pile foundation, and the overall strength and the high-temperature deformation resistance of the pavement structure are effectively improved.
本发明公开了一种降温沥青路面结构及其施工方法，包括沥青面层，沥青面层中均匀穿插有导热棒；沥青面层包括自下而上依次铺设的下面层、中面层及上面层；其中，上面层采用热阻沥青混合料铺筑而成，导热棒竖向埋入下面层、中面层及上面层中；本发明通过在沥青面层中均匀穿插导热棒，上面层采用热阻沥青混合料铺筑而成；通过上面层的阻热和导热棒的导热，双重作用有效降低沥青路面的温度，减小温度梯度；同时，导热棒能够起到桩基的作用，有效提升路面结构的整体强度和高温抗变形能力。
