Roadbase mixture prepared from weathered rock and aggregate strengthening process
The invention provides a road base mixture prepared from weathered rocks. The road base mixture is prepared from the following components in percentage by weight: 3-6% of cement, 0-0.04% of a curing agent, 54-67% of weathered rock reinforced coarse aggregate and 30-40% of weathered rock reinforced fine aggregate, the road base is prepared from the composite stable weathered rock, the problem of broken stone shortage in the mountainous area road construction process can be effectively solved, meanwhile, efficient utilization of roadbed excavation waste slag is achieved, land resources are saved, and the road construction cost is reduced; the weathered rock aggregate strengthening and curing gelling technology is adopted, the anti-scouring performance of a traditional weathered rock base layer is greatly improved, then the water damage resistance of a road is improved, road safety is guaranteed, and the later road operation cost is saved.
本发明提供一种利用风化岩制备的道路基层混合料按重量计，包括以下组分：水泥3%~6%，固化剂0~0.04%，风化岩强化粗集料54%~67%，风化岩强化细集料30%~40%；本发明采用复合稳定风化岩制备道路基层，可以有效解决山区公路修建过程中碎石短缺的问题，同时也实现了路基挖方弃渣的高效利用，节约了土地资源，降低了道路修筑成本；采用风化岩集料强化+固化胶凝技术，大大提高传统风化岩基层的抗冲刷性能性能，进而提高道路抵抗水毁的能力，保障了道路安全，节约了后期道路运营成本。
