Asphalt road capable of reducing pavement temperature
The invention belongs to an asphalt road, and particularly relates to an asphalt road capable of reducing pavement temperature, which is paved by the following method: paving a roadbed and a cushion layer; laying a base layer: adding 1-2% of flaky graphite powder into a base layer material, uniformly mixing, and compacting in a layered manner; and paving a surface layer: adding 0.5-1% of flaky aluminum powder and 1-2% of flaky graphite powder into the asphalt material, uniformly mixing, and paving an asphalt layer. The flaky aluminum powder and the flaky graphite powder can more quickly conduct heat absorbed by the surface layer into the base layer, and can reflect part of sunlight, so that the temperature of the road can be effectively reduced, the service life of the asphalt road can be prolonged, and the maintenance cost can be reduced.
本发明属于沥青公路，特别涉及一种能降低路面温度的沥青公路，采用以下方法铺设而成，铺设路基和垫层；铺设基层：在基层材料中加入1‑2%的鳞片状石墨粉，混合均匀，分层压实；铺设面层：沥青材料中加入0.5‑1%的鳞片状铝粉和1‑2%的鳞片状石墨粉，混合均匀，铺设沥青层。本发明的鳞片状铝粉和鳞片状石墨粉，可以将面层吸收的热量更快地传导到基层中，鳞片状铝粉和鳞片状石墨粉可以将部分阳光反射，因此，可有效降低公路的温度，提高沥青公路的使用寿命，降低维修成本。
