Problems solved by technology

[0003] At present, measures such as modified asphalt, use of high-quality aggregates, skeleton embedded extrusion grading, and addition of anti-rutting agents are widely used in the road material industry to improve the high-temperature performance of asphalt pavement. However, due to the temperature-sensitive nature of asphalt materials, these measures are still The problem of high temperature rutting on asphalt pavement has not been fundamentally solved

Abstract

The invention discloses a sun-heat reflecting coating used for a bituminous pavement and a preparation method thereof. The coating is formed by uniformly mixing film forming matters, pigments, fillers and addition agents the mass ratio of which are sequentially 40 percent-55 percent : 42 percent-55 percent : 3 percent-5 percent, wherein the film forming matters consist of epoxy resin 6101, polyamide polyamine curing agents and acetone or benzyl alcohol diluent the mass ratio of which are sequentially 1:0.3-0.45:0.05-0.15; and the addition agents are formed by mixing dispersing agents, antifoaming agents and flatting agents. The coating is coated at the surface of the bituminous pavement so as to play the favorable effect of reducing the temperature of the bituminous pavement, thus commendably and fundamentally solving the problems such as tracks formed on the bituminous pavement due to high temperature, prolonging the service life of the bituminous pavement; and the coating achieves low cost, simple formula and convenient construction and imposes no influence on the skid resistance of the bituminous pavement.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement, and relates to an asphalt pavement coating, in particular to a solar heat reflective coating capable of significantly reducing the temperature of the asphalt pavement, reducing the rutting disease of the asphalt pavement, and prolonging the service life of the asphalt pavement and a preparation method thereof. Background technique [0002] As a heat-absorbing material, asphalt mixture has a heat absorption rate of 0.85 to 0.95. The high absorption rate of asphalt pavement to sunlight is the main reason for the high temperature of asphalt pavement. In most parts of our country, the highest temperature in summer can reach 35°C-40°C. Under continuous sunlight, a large amount of heat is absorbed by the asphalt pavement and accumulated in the asphalt pavement, and the temperature of the asphalt pavement can reach 63°C-68°C. And make the asphalt pavement produce rutting. Rutting diseases on a...
