Asphalt modifier, asphalt mixture and preparing methods of asphalt modifier and asphalt mixture
The invention discloses an asphalt modifier, an asphalt mixture and preparing methods of the asphalt modifier and the asphalt mixture. The asphalt modifier is made of waste fabric in a processed mode, the maximum nominal grain size of aggregate in the asphalt mixture is set to be r, the length size of the asphalt modifier ranges from 2pir to 4pir, and the cross sectional area of the asphalt modifier is smaller than or equal to 0.01 mm<2>. The asphalt modifier which is made of the waste fabric in the processed mode and has the certain length size is designed according to the fact that the waste fabric has the advantages of being good in elasticity, resistant to shearing, stretching, the high temperature and the low temperature, capable of being dissolved into asphalt and the like based on the coarse aggregate macroscopic binding principle, the modifying effect similar to that of polymer modification agents is achieved in the performance aspect, a direction is provided for large-scale processing of the waste fabric, the applied polymer modification agents are reduced, and the good economic benefits and the good environment-friendly benefits are achieved.
