Modifier for high-water-content clay filler and roadbed filling construction method
The invention provides a modifier for a high-water-content clay filler and a roadbed filling construction method. The modifier comprises the following components in parts by mass: 1 to 50 parts of sodium nitrate, 30 to 150 parts of sodium carbonate, 30 to 150 parts of sodium sulfate, 50 to 200 parts of calcium oxide, 20 to 100 parts of silicon powder, 10 to 100 parts of magnesium oxide, 50 to 200parts of fine sand and 20 to 100 parts of cement. The modifier has the micro-expansion characteristic, the air shrinkage performance of the filler can be improved, and cracking is prevented; comparedwith a roadbed constructed through a traditional improvement method, the roadbed constructed through the construction method is higher in compressive strength, small in frost heaving rate and low in permeability coefficient, and the roadbed and pavement structure performance requirements are met.
本发明提供一种用于高含水率黏土填料的改良剂、路基填筑施工方法，该改良剂按照质量份数计算，包括以下组分：硝酸钠1‑50份、碳酸钠30‑150份、硫酸钠30‑150份、氧化钙50‑200份、硅粉20‑100份、氧化镁10‑100份、细砂50‑200份、水泥20‑100份。该改良剂具有微膨胀特性，能够提高填料的干缩性能，防止开裂，该施工方法施工的路基与传统改良方法施工的路基相比，抗压强度更高，冻胀率小，渗透系数低，满足路基路面结构性能要求。
