Road backfill material and preparation method thereof
The invention provides a road backfill material and a preparation method thereof. The backfill material comprises the following components in parts by weight: 60-70 parts of regenerated micro powder, 240-250 parts of cement, 600-610 parts of tap water and 1033-1043 parts of subway muck. The road backfill material is prepared from the regenerated micro powder, the subway muck and the fly ash, has proper strength, can meet most backfill scenes, can also be subjected to secondary excavation and backfill, reduces the road construction difficulty and shortens the construction period. The recycling value and the environmental value of the regenerated micro powder, the subway muck and the fly ash are realized, the carbon emission is reduced, and the green transformation of the construction process is realized.
本发明提供一种道路回填材料及制备方法，回填材料包括如下组分配比：再生微粉60～70份，水泥240～250份，自来水600～610份，地铁渣土1033～1043份。该材料利用再生微粉、地铁渣土、粉煤灰制作道路回填材料，具有合适的强度，既可以满足大多数回填场景，同时还可以进行二次开挖回填，降低了道路施工难度，缩短施工工期。实现了再生微粉、地铁渣土、粉煤灰的资源化价值和环境价值，降低碳排放，实现施工工艺绿色化转型。
