Asphalt mixture doped with waste glass aggregate and preparation method of asphalt mixture
The invention discloses an asphalt mixture doped with waste glass aggregate and a preparation method of the asphalt mixture, and aims to improve the doping amount of the waste glass aggregate to about30% to the maximum extent by taking fixed mineral aggregate gradation and replacing mineral aggregates with corresponding particle sizes with the same mass of the waste glass aggregate. Meanwhile, the problem that the adhesiveness of common asphalt and glass aggregate is insufficient is solved. The obtained mixture not only can keep good pavement performance, but also can reduce the pavement surface temperature in summer. In addition, the use of the mixture can greatly promote the recycling of the waste glass, and accords with the ideas of green energy conservation, environmental protection and sustainable development. The asphalt mixture is prepared from the following components in parts by mass: 4.3 to 5.3 parts of matrix asphalt, 2.5 to 7.5 parts of waste glass aggregate, 60.1 to 63.0parts of coarse aggregate, 22.9 to 25.2 parts of fine aggregate and 4.7 to 4.8 parts of mineral powder.
本发明公开了一种掺配废玻璃集料的沥青混合料及其制备方法，目的在于，通过取定矿料级配，利用废玻璃集料等质量替代对应粒径矿料，最大可以将废玻璃集料掺量提高到30％左右；同时解决了普通沥青与玻璃集料黏附性不足的问题。所得混合料不仅能保持良好的路用性能，而且能够降低夏季路表温度。此外，该混合料的使用可大量促进废玻璃的回收利用，符合绿色节能环保和可持续发展理念。沥青混合料按质量份计，包括4.3～5.3份的基质沥青、2.5～7.5份的废玻璃集料、60.1～63.0份的粗集料、22.9～25.2份的细集料、4.7～4.8份的矿粉。
