Road roadbed material for curing high-water-content shield muck and preparation method of road roadbed material

The invention provides a road subgrade material for curing high-water-content shield muck and a preparation method thereof, the road subgrade material is prepared from the high-water-content shield muck and a composite curing agent, and the mass parts of the high-water-content shield muck and the composite curing agent are as follows: 100 parts of the high-water-content shield muck and 2-8 parts of the composite curing agent; the composite curing agent comprises the following components in parts by weight: 2-10 parts of cement, 2-10 parts of fly ash, 1-5 parts of calcium sulfate, 1-5 parts of calcium oxide and 1-3 parts of sodium polyacrylate. According to the roadbed material, the high-water-content shield muck serves as a base material, a certain amount of cement-based materials and high-molecular polymers are doped for solidification, the physical and chemical properties and mechanical properties of solidified soil are improved, and the high-water-content shield muck is fully utilized. 本发明提供一种固化高含水率盾构渣土的道路
