Modified steel slag aggregate asphalt mixture and preparation method thereof
The invention belongs to the technical field of asphalt concrete, and particularly relates to a modified steel slag aggregate asphalt mixture and a preparation method thereof. The modified steel slag aggregate asphalt mixture is prepared from the following raw materials: steel slag aggregate, RO fly ash, modified fibers, amino resin modified asphalt and stearate modified limestone mineral powder, wherein the RO fly ash and the modified fiber are uniformly dispersed on the surface of the steel slag aggregate to form a modified steel slag aggregate; the amino resin modified asphalt is coated with the modified steel slag aggregate to form a steel slag asphalt mixture; pores of the steel slag asphalt mixture are filled with the stearate modified limestone mineral powder. According to the modified steel slag aggregate asphalt mixture, a multi-stage anti-expansion structure is innovatively designed, so that the problem of pavement diseases caused by easy expansion of the steel slag asphalt mixture is fundamentally solved, the stability of the steel slag is effectively enhanced, the pavement performance of the steel slag asphalt mixture is greatly improved, and the service life of the steel slag asphalt mixture is greatly prolonged.
本发明属于沥青混凝土的技术领域，具体的涉及一种改性钢渣集料沥青混合料及其制备方法。该种改性钢渣集料沥青混合料，其原料包括钢渣骨料、RO粉煤灰、改性纤维、氨基树脂改性沥青和硬脂酸盐改性石灰岩矿粉；其中，RO粉煤灰和改性纤维均匀分散在钢渣骨料的表面，形成改性钢渣集料；氨基树脂改性沥青裹附着改性钢渣集料，形成钢渣沥青混合料；硬脂酸盐改性石灰岩矿粉填充在钢渣沥青混合料的孔隙中。该改性钢渣集料沥青混合料创新性地设计多级防膨胀结构，从根本上解决了钢渣沥青混合料易产生膨胀导致路面病害的难题，有效增强了钢渣的安定性，大幅度提升钢渣沥青混合料的路用性能和使用寿命。
