High-performance temperature-control phase-change asphalt pavement material and preparation method thereof
The invention relates to the field of pavement materials, and discloses a high-performance temperature-control phase-change asphalt pavement material and a preparation method thereof.The phase-change temperature-adjustment asphalt composite material is prepared by simultaneously and partially replacing mineral filler and fine aggregate with two macroscopic coating type porous-base shaped composite phase-change materials with different particle sizes in an isometric mode; the macroscopically coated porous-based shaped composite phase-change material is prepared by directly doping the macroscopically coated porous-based shaped composite phase-change material into an asphalt mixture, and the macroscopically coated porous-based shaped composite phase-change material is prepared by firstly adsorbing the phase-change material by using a porous inorganic mineral medium and then coating the phase-change material by using an organic resin coating so as to achieve a further packaging and shaping effect on the phase-change material. According to the prepared phase-change temperature-regulating asphalt composite material, the temperature-regulating effect of the phase-change material is utilized, so that the pavement temperature field of an asphalt steel bridge deck pavement upper layer is controlled.
本发明涉及路面材料领域，且公开了一种高性能控温相变沥青路面材料及其制备方法，相变调温沥青复合材料是将两种不同粒径的宏观包覆型多孔基定型复合相变材料同时等体积部分替代矿物填料和细集料，将其直接掺入到沥青混合料中制备而成的，其中宏观包覆型多孔基定型复合相变材料是先利用多孔无机矿物介质吸附相变材料，后采用有机树脂涂层包覆实现对相变材料进一步地封装定型效果。所制备的相变调温沥青复合材料利用相变材料的调温效果，进而实现控制沥青钢桥面铺装上层的路面温度场。
