Environment-friendly steel slag hot recycled asphalt mixture
The invention provides an environment-friendly steel slag hot recycled asphalt mixture. The environment-friendly steel slag hot recycled asphalt mixture comprises the following raw materials in percentage by weight: 25-70% of steel slag aggregate, 25-70% of an asphalt pavement milling reclaimed material, 1.8-3.5% of asphalt and 1.1-1.6% of natural mineral powder. When the plant-mixed hot recycled asphalt mixture is produced, the industrial waste steel slag is used for replacing newly added natural mineral aggregate required by the recycled mixture, so that the dependence on the natural mineral aggregate can be completely eliminated, the material cost of asphalt pavement maintenance engineering is reduced, the recycling of solid wastes is realized, and important economic, environmental and social values are achieved.
本发明提供了一种环保型钢渣热再生沥青混合料，包括如下重量比的原料：钢渣集料25~70%、沥青路面铣刨回收料25~70%、沥青1.8~3.5%以及天然矿粉1.1~1.6%。由于在生产厂拌热再生沥青混合料时，采用工业废弃物钢渣替代再生混合料所需的新加天然矿料可以完全摆脱对天然矿料的依赖，降低沥青路面养护工程的材料成本，实现固体废弃物的循环利用，具有重要的经济、环境和社会价值。
