Anti-crack semi-rigid base material and preparation method thereof
The invention provides an anti-crack type semi-rigid base material and a preparation method thereof. The anti-crack type semi-rigid base material comprises the following raw materials: cement, steel slag, mineral slag, fly ash, an anti-crack reinforcing agent and a certain proportion of water. The anti-crack semi-rigid base material has the following advantages: (1) in response to the call of the national academic, various industrial wastes are used for replacing natural stones and cement, so that the consumption of natural resources is reduced; (2) industrial waste is used for the road base, land occupation is reduced, water source pollution is avoided, and the natural environment is protected; (3) the mechanical property of the mixture is improved by utilizing the characteristics of industrial wastes, and the road engineering quality is improved; (4) the cracking problem of the semi-rigid base layer is solved, and pavement diseases caused by reflection cracks are avoided; (5) industrial wastes are used as engineering aggregates and binding materials, so that the construction cost is saved; (6) the service life of the road is prolonged; and (7) the maintenance workload is reduced, and the road maintenance cost is saved.
本发明提出了一种抗裂型半刚性基层材料及制备方法，涉及的原材料包括水泥、钢渣和矿渣、粉煤灰、抗裂增强剂和一定比例的水。该抗裂型半刚性基层材料具有如下优点：（1）响应国务院号召，用多种工业废料替代天然石料与水泥，减少天然资源消耗；（2）将工业废料用于道路基层，减少土地占用、避免水源污染，保护自然环境；（3）利用工业废料特性提高混合料力学性能，提高道路工程质量；（4）解决半刚性基层的开裂问题，避免反射裂缝引起的路面病害；（5）用工业废料作工程骨料与结合料，节约建设成本；（6）延长道路的使用寿命；（7）减少养护工作量，节约道路养护成本。
