In order to study the construction technology of large-thickness cement-stabilized macadam base. Based on the Ushant Connecting Line Project of Kaiyang Expressway in Guangdong Province， experimental roads were paving with five different rolling compaction combinations.The detection of compaction degree，roughness，deflection test indicators，and the unconfined compressive strength of different rolling combinations was measured by drilling core sampling，and the implementation effects of different compaction combinations were compared. The results show that the fourth rolling compaction process(the rolling times of 39t vibratory roller should be controlled at 3 times)can achieve the best compaction effect after disposable paving of large thickness cement stabilized macadam base.The research results can provide reference for the key points of construction technology and quality control of similar projects.
