Comprehensive improvement method of cold recycled lime soil subbase in situ

The invention discloses a comprehensive improvement method of in-situ cold recycled lime soil subbase, which comprises the following steps: 1, milling and planing the original pavement structure; 2, perform performance analysis; 3, arrange a gray grid; 4, pave that admixture; 5, regenerate that cold regenerator; 6, control that moisture content and mixing; 7, compact and forming; 8, compact and curing. In the invention, the road cold recycling on the spot utilizes all the old paving materials, thereby reducing the excavation and transportation of the old paving materials, the scrap and the purchase of new materials during the road maintenance or reconstruction, and causing the cost to be greatly reduced; But also minimize the traffic disruption caused by the construction. 本发明公开了种就地冷再生石灰土底基层的综合改良方法，包括：步骤、原路面结构铣刨；步骤二、性能分析；步骤三、布设灰格；步骤四、摊铺外加剂；步骤五、冷再生机再生；步骤六、含水量控制及拌合；步骤七、压实成型；步骤八、压实养护。本发明中，道路就地冷再生由于全部利用了旧的铺层材料，从而减少了道路维修或改造时旧铺层材料的挖起运输、废置和新材料的购置，导致成本大幅度下降；而且将因施工而造成的交通干扰降到最低。
