Warm-mixing SMA (styrene maleic anhydride)-modified asphalt concrete modified particle and preparation method thereof
The invention discloses a warm-mixing SMA (styrene maleic anhydride)-modified asphalt concrete modified particle. The warm-mixing SMA-modified asphalt concrete modified particle comprises the following components in percentage by mass: 30-40% of rubber powder, 15-25% of diatomite, 8-15% of an ethylene-vinyl acetate copolymer, 5-10% of a warm-mixing agent, 5-10% of polyester fibers, 5-8% of paraffin and 2-3.5% of an anti-stripping agent, based on 100% in total. The invention further discloses a preparation method of the modified particle. According to the warm-mixing SMA-modified asphalt concrete modified particle disclosed by the invention, additives with different modifying functions are physically co-mixed and chemically modified and mixed to prepare the modified particle which is used for paving high-grade asphalt pavement, so that a conventional SBS (styrene butadiene styrene) asphalt modifying technology production process is replaced, the problems in transportation, storage and the like of the SBS modified asphalt are solved, the investment, the pollution and the energy consumption are reduced, the comprehensive road performances of the asphalt pavement are improved, the service life of the pavement is prolonged, the road construction cost and the maintenance cost are reduced, and the economic value and the social benefits are extremely high.
