Remixing regenerated cement stabilized macadam base material and cement stabilized macadam base
The invention discloses a remixed regenerated cement stabilized macadam base material and a cement stabilized macadam base, and belongs to the field of road engineering. The cement stabilized macadam base material comprises a skeleton aggregate, a recycled aggregate interface treating agent and a recycled powder composite filler, the skeleton aggregate comprises recycled aggregate, the recycled aggregate interface treating agent is composed of cement, slaked lime, glass beads and a powder humectant, and the recycled powder composite filler is composed of a main material and an additive. The main material is composed of recycled powder, fine aggregate and cement, and the weight ratio of the recycled powder to the fine aggregate to the cement is (55-65): (20-40): (10-15). Compared with the prior art, by adopting the special grading and construction technology, the dry shrinkage and temperature shrinkage performance of the water-stable macadam base can be improved, transverse cracks of the semi-rigid base are reduced, the service life of the pavement structure is prolonged, and good application and popularization value is achieved.
本发明公开了一种复拌再生水泥稳定碎石基层材料及水泥稳定碎石基层，属于道路工程领域。所述水泥稳定碎石基层材料包括骨架集料、再生骨料界面处理剂和回收粉复合填料，所述骨架集料包括再生骨料，所述再生骨料界面处理剂由水泥、熟石灰、玻化微珠及粉末保湿剂组成，所述回收粉复合填料由主料、添加料组成，所述主料由回收粉、细骨料、水泥组成，回收粉、细骨料、水泥的重量比是(55‑65):(20‑40):(10‑15)。与现有技术相比，本发明通过采用特殊级配和施工工艺，能够改善水稳碎石基层的干缩和温缩性能，减少半刚性基层的横向裂缝，提高路面结构的使用寿命，具有很好的推广应用价值。
