Modified steel slag asphalt mixture and preparation method thereof
The invention belongs to the technical field of road paving materials, and particularly relates to a modified steel slag asphalt mixture and a preparation method thereof. The modified steel slag asphalt mixture comprises the following raw materials in parts by weight: 100 parts of steel slag aggregate, 6-8 parts of a steel slag modifier, 4-6 parts of asphalt and 4-12 parts of mineral powder, wherein the mixing amount of steel slag in the steel slag aggregate is 75-100 wt%; the steel slag aggregate forms a framework of the modified steel slag asphalt mixture, a layer of steel slag modifier is adhered and wrapped on the surface of the steel slag aggregate, and the steel slag modifier is adhered with asphalt to form a cross-linked spatial network structure; the mineral powder is adhered to the asphalt. The modified steel slag asphalt mixture not only effectively solves the problems that the steel slag asphalt mixture is poor in water stability and easy to swell and crack when meeting water, but also can greatly improve the dosage of the steel slag aggregate in the steel slag asphalt mixture without increasing the dosage of asphalt.
本发明属于道路铺装材料的技术领域，具体的涉及一种改性钢渣沥青混合料及其制备方法。所述改性钢渣沥青混合料，包括以下重量份的原料：钢渣骨料100份，钢渣改性剂6‑8份，沥青4‑6份，矿粉4‑12份；其中，钢渣骨料中的钢渣掺量为75wt％‑100wt％；所述钢渣骨料形成改性钢渣沥青混合料的骨架，在钢渣骨料的表面黏结裹附一层钢渣改性剂，该钢渣改性剂与沥青相黏结，形成交联的空间网络结构；矿粉黏附于沥青上。该改性钢渣沥青混合料不仅有效解决了钢渣沥青混合料水稳定性差，遇水易膨胀开裂的问题，而且能够大幅度提高钢渣骨料在钢渣沥青混合料中掺加量同时还不会增加沥青的用量。
