Problems solved by technology

Although the pavement technology of this kind of pavement is simple and low in cost, it will bring many negative effects to the ecological environment of the city.
First of all, this kind of impermeable and airtight pavement significantly reduces the rainwater infiltrated into the ground, and the urban groundwater cannot be replenished, which damages the city's water balance, affects the growth of urban surface plants, and destroys the ecological balance of the urban surface; secondly, Due to the inability to drain water in time on rainy days, this kind of dense pavement will cause water accumulation on the road, which will bring a lot of inconvenience to pedestrians and vehicles, and will also increase the noise pollution of the city and form the city's "heat island effect".

Abstract

The invention discloses high-performance colorized water-permeable asphalt concrete and a preparation method thereof. The high-performance colorized water-permeable asphalt concrete is prepared from mineral aggregate, a colorless bonding material and a pigment satisfying grading requirements through mixing according to a mass ratio of 100: 4.5-7.5: 1.5-2.5, wherein the colorless bonding material is prepared from base oil, petroleum resin, a polymer and a coupling agent according to a mass ratio of 40-60: 30-45: 2-25: 0.05-3.0 through blending. The high-performance colorized water-permeable asphalt concrete has a red, yellow, green, blue or silver gray color, has pavement performances completely according with or exceeding the JTG F40-2004 road asphalt pavement construction technology standard requirements and is suitable for low carbon green road surfaces of various roads, squares, parks and stadiums.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering construction, and in particular relates to a colored permeable asphalt concrete and a preparation method thereof. Background technique [0002] With the development of economy and the acceleration of urban construction, the surface of modern cities is being gradually covered by reinforced concrete houses and impermeable concrete pavement. At present, the pavements of urban streets, sidewalks, bicycle lanes, parks, courtyards and public squares in China are mainly made of impermeable stone plates and concrete. Although the pavement technology of this kind of pavement is simple and the cost is low, it will bring many negative effects to the ecological environment of the city. First of all, this kind of impermeable and airtight pavement significantly reduces the rainwater infiltrated into the ground, and the urban groundwater cannot be replenished, which damages the city's water balanc...
