Problems solved by technology

At present, the common measures to solve the urban "heat island effect" are to increase the urban forest coverage rate and expand the grassland and water area to change the state of the underlying surface of the city. However, the city is an area with dense buildings and dense roads. It is extremely difficult to increase the forest coverage rate of
[0004] Moreover, the road surfaces in our country are mostly gray or black. Gray and black have a calming effect on the human nervous system, but staring at the monotonous gray road surface for a long time will make the driver's attention dull, induce fatigue, and even drowsiness. increase the risk of traffic accidents

Abstract

The invention discloses a colored solar heat reflecting coating for a bituminous road surface, which consists of a film forming matter, a function pigment, a coloring pigment and an auxiliary agent. The weight ratio of the film forming matter, the function pigment, the coloring pigment and the auxiliary agent is 48%-58%: 32%-42%:3%-5%:3%-5%. The coloring pigment comprises a red pigment and a green pigment, wherein the red pigment is iron oxide red, and the green pigment is chromium oxide green. When the colored solar heat reflecting coating is coated on the bituminous road surface, high-temperature rut diseases of the bituminous road surface can be obviously reduced, the service life of the bituminous road surface can be prolonged, the heat island effect of a city can be eased, the road landscape can be beautified, visual fatigue of a driver can be eased, the safety performance of a road can be improved, management of traffic flow can be induced, the traffic capacity of the road can be increased, meanwhile, the cost is low, the formula is simple, the construction is convenient, and the skid resistance performance of the bituminous road surface is not affected.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement, and relates to a colored asphalt pavement coating, in particular to a coating that can significantly reduce the temperature of asphalt pavement, reduce the rutting disease of asphalt pavement, alleviate the urban "heat island effect", beautify the road landscape, and improve road traffic safety Colored asphalt pavement solar heat reflective coating. 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 pavemen...
