Problems solved by technology

[0002] In summer, under the action of continuous solar radiation, a large amount of solar radiation is absorbed by the asphalt concrete pavement in the form of heat and accumulates in the asphalt concrete surface layer, which causes the temperature of the asphalt concrete pavement to be much higher than the air temperature, thus causing two hazards: 1) The high temperature reduces the bearing capacity of asphalt concrete, resulting in serious rutting on the asphalt concrete pavement; 2) The high temperature of asphalt concrete intensifies the urban "heat island effect"

Abstract

The invention discloses an asphalt pavement heat-reflecting material, comprising 30-40 parts of polypropionic acid resin, 10-20 parts of polyoxyethylene polyoxypropylene pentaerythritol ether, 10-20 parts of dibutyl maleate-vinyl acetate copolymer, 2-6 parts of 3-glycidoxypropyltrimethoxysilane, 4-9 part of silicic acid, 1-5 parts of rutile titanium dioxide, 5-10 parts of expanded perlite, 2-6 parts of indium oxide micropowder, 1-3 parts of hydroxyethyl cellulose, 5-10 parts of nano hollow glass fiber, 2-6 parts of a near-infrared reflecting material, 2-6 parts of ethylene-vinyl acetate copolymer, and 1-3 parts of a dispersant. The asphalt pavement heat-reflecting material can absorb visible light with wavelength of 400-750 nm in sunlight and reflect the visible light under reduced quantity, and can reflect most of the non-visible light with wavelength of 750-2500 nm, the effective reflection rate is up to 80-90%, cooling is achieved accordingly, temperature rise may reach 10-18 DEG C,road heat storage can be lessened so that rutting damage to an asphalt concrete pavement is reduced, the service life of the pavement is extended, driving safety is improved, and durability and anti-rutting of the pavement can be improved.

Description

technical field [0001] The invention relates to a thermal insulation material for road surfaces, in particular to a heat-reflecting material for asphalt pavement. Background technique [0002] In summer, under the action of continuous solar radiation, a large amount of solar radiation is absorbed by the asphalt concrete pavement in the form of heat and accumulates in the asphalt concrete surface layer, which causes the temperature of the asphalt concrete pavement to be much higher than the air temperature, thus causing two hazards: 1) The high temperature reduces the bearing capacity of asphalt concrete, resulting in serious rutting on the asphalt concrete pavement; 2) The high temperature of asphalt concrete intensifies the urban "heat island effect". Contents of the invention [0003] In view of this, the object of the present invention is to provide a heat-reflecting material for asphalt pavement, which can control the increase of road surface temperature by reducing th...
