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 area of grassland and water 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 heat-reflecting high-molecular composite modified colored emulsified asphalt and a mixture thereof. The heat-reflecting high-molecular composite modified colored emulsified asphalt is characterized by being prepared from a clear color resin emulsion, a water-based resin emulsion, a near-infrared reflecting pigment, sericite in powder, nanometer far-infrared radiation powder, a dispersing agent and water; meanwhile, the heat-reflecting high-molecular composite modified colored emulsified asphalt mixture is prepared by adding a pH regulating agent, a thickening agent, a grading rock material and the water to the prepared emulsified asphalt. The heat-reflecting high-molecular composite modified colored emulsified asphalt disclosed by the invention can outstandingly reduce the high-temperature track diseases of an asphalt pavement, prolong the service life of the asphalt pavement, relieve the heat island effect of a city, beautify the road landscape and enhance the road safety property, and has the advantages of low integrated cost, simple formula and convenience for production and construction.
Description
technical field [0001] The invention belongs to the technical field of asphalt pavement, and relates to a heat-reflecting colored emulsified asphalt and a mixture 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. High temperature is the most direct cause of rutting: high temperature transforms the rheological properties of asphalt from viscoelasticity to plasticity, the stiffness modulus drops sharply, and its anti-deformation ability decreases sharply. Sever...
