Abstract

A water-retaining and cooling material for road is disclosed, which is prepared by using, in parts by weight, 30-80 parts of cement, 10-100 parts of inorganic mineral, 0.1-10 parts of water-absorbing resin, 20-100 parts of fly ash and 50-300 parts of water, wherein the inorganic mineral is a composition containing one or more materials selected from sodium bentonite, kaolin, kieselguhr, pottery sand, montmorillonite and mineral slag in any ratio. The water-retaining and cooling material disclosed by the invention is injected into a macroporous bituminous concrete matrix, as well as is great in water-absorbing performance and water-retaining performance; with the gradual rising of the temperature of road surface, lowering for the temperature of road surface by greater than 10 DEG C can be realized, and transferring for temperature to the structural layer of road surface can be efficiently prevented; and road surface paved and poured with the water-retaining and cooling material disclosed by the invention in large area in city efficiently relieves urban heat island effect.

Description

technical field [0001] The invention relates to a water-retaining and cooling material, in particular to a water-retaining and cooling material for road surfaces and a preparation and construction method thereof, belonging to the technical field of new environmental protection engineering. Background technique [0002] With the rapid development of urbanization and industrialization, the urban population density, building density, and factory density have increased sharply; resulting in the urban temperature in the spatial distribution of the heat island phenomenon, which is higher in the center and lower in the suburbs. The impact of heat island effect on the urban environment is becoming more and more serious, and it also has a negative impact on the physical and mental health of urban residents. Among the many factors that cause the heat island effect, the thermal structure of urban roads, parking lots, sidewalks and other pavements has the most serious impact on the ther...
