Rubber asphalt mixture using steel slag as coarse aggregate and preparation method thereof
The invention discloses a rubber asphalt mixture using steel slag as coarse aggregate and a preparation method thereof, and relates to the technical field of asphalt mixtures. The technical key pointsare as follows: the rubber asphalt mixture using the steel slag as the coarse aggregate comprises 150-200 parts of steel slag coarse aggregate; 15 to 30 parts of fine aggregate; 10 to 15 parts of rubber asphalt; 5-10 parts of filler. The preparation method comprises the following steps: S1, adding the steel slag coarse aggregate, the fine aggregate and the filler into a stirring cylinder, and uniformly stirring and mixing to obtain a mixture; S2, putting the mixture into a drying barrel, and drying the mixture at 120-170 DEG C until the weight of the mixture is constant; and S3, pouring the dried mixture into mixing equipment, adding rubber asphalt, and performing uniform mixing at a rotating speed of 600-800r/min so as to obtain the mixture. The asphalt mixture prepared by the method hasthe advantages of high strength, strong impact resistance and good use durability.
本发明公开了一种利用钢渣作为粗集料的橡胶沥青混合料及其制备方法，涉及沥青混合料技术领域。其技术要点是：一种利用钢渣作为粗集料的橡胶沥青混合料，包括钢渣粗集料150‑200份；细集料15‑30份；橡胶沥青10‑15份；填料5‑10份。其制备方法为：S1，将钢渣粗集料、细集料和填料加入到搅拌缸中，搅拌混合均匀，得到混合物；S2，将上述混合物置于烘干桶中，于120‑170℃下烘干至恒重；S3，将烘干后的混合物倒入拌和设备中，并加入橡胶沥青，于600‑800r/min转速下拌和均匀，即得。本发明制备得到的沥青混合料具有强度高、抗冲击能力强和良好使用耐久性能的优点。
