Water retention and cooling asphalt layered pavement
The invention relates to a water retention and cooling asphalt layered pavement, which comprises a base layer and a water retention layer. The base layer is a flat surface structure with an entity surface inside, the water retention layer is located on the surface of the base layer, and is formed by perfusion of water retention mortar to the surfaces of a plurality of asphalt mixture skeletons till final setting, and the asphalt mixture skeletons are arranged at an interval, and the water retention mortar is composed of water and cement in a ratio of 1.38-1.5, 18-24% of river sand, 8-13% of mineral powder, 4-8% of a water retaining agent and 4-8% of fly ash. The water retention and cooling asphalt layered pavement provided by the invention has a surface with strong water absorption and water retention capacity, can quickly eliminate road surface, square and residential area water accumulation, alleviate urban drainage burden, ease road surface water mist and enhance road traffic safety; the water retention and cooling asphalt layered pavement can store rainwater and perform heat exchange, adjust urban space temperature and humidity and alleviate urban heat island effect; and under the circumstance of ensuring sufficient compressive strength and flexural strength, the water retention and cooling asphalt layered pavement can significantly reduce material consumption and lower cost.
