Asphalt modified with red mud for porous pavement material and application thereof
The present disclosure provides asphalt modified red mud for porous pavement material and an application thereof. The porous asphalt pavement material includes asphalt, red mud and aggregate; the mass ratio of asphalt to red mud is 1:(0.10-0.15), the mass ratio of the total mass of asphalt and red mud to aggregate is (0.08-0.12):1. With regard to the asphalt modified with red mud for porous pavement material provided in the present disclosure, asphalt is modified with red mud, and aggregate is added to synergize with red mud so as to improve the purification properties and mechanical properties of the porous asphalt pavement material efficiently. In the embodiments of the present disclosure, the purification rate of suspended matter by the asphalt modified with red mud for porous pavement material reaches 54.9-58.6%, and the purification rate of heavy metals (iron and lead) reaches 34.3-46.1%.
