Roadbed filler and preparation method thereof
The invention provides roadbed filler and a preparation method thereof. The roadbed filler comprises a filler A and a filler B, wherein the filler A comprises cement, coal-based solid waste, water and a water reducing agent; the filler B is prepared from crushed rubber waste particles, sepiolite, bisphenol A glycidyl ether dimethacrylate and a dispersing agent; the mass content of the filler B is 16.5-23.5% by taking the total mass of the filler A as 100%. The roadbed filler has the advantages of being high in flow state, light in weight, free of rolling and vibrating, high in compressive strength, low in manufacturing cost, wide in material source and the like. In addition, the roadbed filler not only reduces the dead weight of an embankment and the additional stress of a foundation, but also improves the compaction quality of the roadbed filler, and is particularly suitable for engineering construction such as bridge and culvert abutment back backfilling and the like.
本发明提供了一种路基填料及其制备方法。该路基填料包括填料A和填料B；其中，填料A包括水泥、煤基固废、水和减水剂；填料B包括橡胶废料粉碎颗粒、海泡石、双酚A缩水甘油醚二甲基丙烯酸酯和分散剂；以填料A的总质量为100％计，填料B的质量含量为16.5～23.5％。本发明的路基填料具有高流态、质地轻、无需碾压和振捣、抗压强度高、造价低和材料来源广等优点。此外，本发明的路基填料不仅减轻了路堤自重和地基附加应力，还提高了路基填料的压实质量，特别适用于桥涵台背回填等工程建设中。
