Pavement pit slot repairing material and preparation method thereof
The invention discloses a pavement pothole repair material and a preparation method thereof.The preparation method comprises the steps that pebbles and polyurethane in raw materials are sequentially put into a mixing pot to be subjected to dry mixing for 2-3 min till the pebbles and the polyurethane are stirred to be uniform, and therefore a large-gap matrix mixture is obtained; then, sequentially putting the fly ash, the steel slag and the blast furnace slag in the raw materials into a mixing pot, carrying out dry mixing for 3 minutes until the raw materials are uniformly mixed, then adding water, a sodium hydroxide aqueous solution and water glass, and continuously stirring for 3 minutes, so as to obtain the solid waste-based grouting material; finally, the obtained solid waste-based grouting material is poured into the large-gap matrix mixture; and curing for 24 hours to obtain the pavement pit slot repairing material. Under the condition that the large-gap matrix mixture and the solid waste grouting material are mutually embedded, extruded and supported, the structural stability of the pit slot repairing material is remarkably improved, so that the pavement performance and durability of the repaired pit slot are remarkably improved.
本发明公开了一种路面坑槽修复材料及其制备方法，将原料中的石子、聚氨酯依次放入拌合锅中进行干拌2‑3mi n直至搅拌均匀，由此得到大空隙基体混合料；然后，将原料中的粉煤灰、钢渣和高炉矿渣依次放入拌和锅中进行干拌3mi n直至搅拌均匀，然后加入水、氢氧化钠水溶液和水玻璃，继续搅拌3mi n后，得到固废基灌浆材料；最后，将得到的固废基灌浆材料灌入到大空隙基体混合料中；养生24小时后即可得到一种路面坑槽修复材料。大空隙基体混合料和固废基灌浆材料在相互嵌挤、相互支撑的情况下，显著提高了坑槽修复材料的结构稳定性，从而使得修复后坑槽的路用性能和耐久性得到显著提升。
