Sand yard waste mud cake roadbed and construction method thereof
The invention provides a sand yard waste mud cake roadbed and a construction method, and belongs to the field of soil roadbeds. The invention provides a sand yard waste mud cake roadbed which comprises the following components in parts by mass: 100 parts of sand yard waste mud cakes by dry weight; 1.5 to 3.0 parts of cement; 0.3 to 0.5 part of a starch/polyamine compound; and 0.1 to 0.3 part of magnesium oxide. The engineering property of the sand yard waste mud cake roadbed filler is changed through the combined action of the cement, the starch/polyamine compound and the magnesium oxide expanding agent, so that the influence of saturated water and dry-wet cycle on the mechanical property of the roadbed material is reduced, and the problems of long-term strength and stability of a single sand yard waste mud cake roadbed are solved; subgrade hidden dangers are reduced, and the engineering utilization value of the sand yard waste mud cakes is improved.
本发明提供了一种砂场废弃泥饼路基及施工方法，属于土路基领域。本发明提供了一种砂场废弃泥饼路基，以质量份数计，包括以下组分：以干重计的砂场废弃泥饼100份；水泥1.5～3.0份；淀粉/聚胺复合物0.3～0.5份；氧化镁0.1～0.3份。本发明通过水泥、淀粉/聚胺复合物和氧化镁膨胀剂的共同作用改变了砂场废弃泥饼路基填料的工程性质，这种共同作用使路基材料力学性能受饱水及干湿循环的影响得到减小，解决了单一砂场废弃泥饼路基的长期强度和稳定性问题，减少了路基隐患，提高砂场废弃泥饼的工程利用价值。
