Abstract:
    The present invention discloses modified asphalt prepared with oceanic polymetal nodule-crust leaching slag and its preparation process. The modified asphalt prepared is prepared with oceanic polymetal nodule-crust leaching slag in 3.8-10.7 % and asphalt in 89.3-96.2 % as material, and through pre-treatment of the leaching slag, smelting, stirring, debubbling, cooling and other steps. The modified asphalt prepared with oceanic polymetal nodule-crust leaching slag has low porosity, high softening point, high adhesion, high durability, simple preparing process, high compatibility and low cost.
