Polymer modified asphalt concrete

The invention provides polymer modified asphalt concrete. The polymer modified asphalt concrete is prepared from raw materials in parts by weight as follows: 100 parts of mineral aggregate, 3-7 parts of asphalt, 0.2-2 parts of a polymer, 0.01-0.3 parts of an improver, 0.01-0.3 parts of a stabilizer and 0.001-0.06 parts of a coupling agent. The asphalt concrete has good pavement performance, the preparation process is simple, the raw materials are non-toxic and harmless, and the polymer modified asphalt concrete can reduce the pavement temperature in the summer high-temperature season and improve the pavement temperature in a cold season and has a great significance in prolonging of the service life of the asphalt pavement. The polymer modified asphalt concrete belongs to environment-friendly non-toxic and non-corrosive composite asphalt and has good pavement performance; the raw materials are widely sourced, the production process is non-pollution, and the price is low. The polymer modified asphalt concrete has a simple preparation process, low cost and good economic efficiency.
