水泥稳定碎石基层大厚度施工压实工艺研究

Research on Compaction Technology of Cement Stabilized Macadam Base with Large Thickness

摘要: 本文依托水泥稳定碎石基层试验段进行了大厚度施工压实工艺研究，检测结果表明：单层施工压实厚度36 cm的水泥稳定碎石基层压实质量可满足设计要求；碾压时遵循先轻后重、先慢后快、从低到高的原则，碾压段落长度宜控制在30~50 m之间；采用分层、整层相结合的压实度检测方法可有效控制大厚度水泥稳定碎石基层施工质量。

Abstract: Based on the test section of cement stabilized macadam base, this paper studies the compaction technology of large thickness construction. The test results show that the compaction quality of cement stabilized macadam base with single layer construction compaction thickness of 36 cm can meet the design requirements; the rolling should follow the principle of light before heavy, slow before fast, from low to high, and the length of rolling section should be controlled between 30~50 m; the construction quality of cement stabilized macadam base with large thickness can be effec-tively controlled by using the compaction detection method of layered and whole layer.
