![摘 要：為解決水泥穩定碎石基層邊部坍塌及強度不足問題，應用徐州新遠建設的邊部注漿機對水泥穩定碎石基層邊部進行了注漿加固，采用無側限抗壓強度試驗測試了不同注漿量的水穩基層芯樣強度，依托廣東懷陽高速、雲茂高速公路和甘肅景中高速公路進行了工程應用，結果表明：水灰比宜控製為2:1，注漿宜按照2.0L/m~3.0L/m進行控製，按照水灰比為2:1，注漿量為2.0L/m~3.0L/m進行邊部注漿能提高水泥穩定碎石基層邊部芯樣強度119~152%，邊部注漿有效改善水泥穩定碎石基層邊部坍塌問題，使得水穩材料基層邊部線型順直美觀。]()

![Abstract:In order to solve the problem of edge collapse and insufficient strength of cement stabilized macadam base, the edge grouting machine of Xuzhou Xinyuan construction was used to reinforce the edge of cement stabilized macadam base. The unconfined compressive strength test was used to test the core strength of cement stabilized macadam base with different grouting amount. The engineering application was carried out relying on Guangdong Huaiyang expressway, Yunmao Expressway and Gansu Jingzhong expressway, The results show that: the water cement ratio should be controlled as 2:1, the grouting should be controlled as 2.0l/m ~ 3.0l/m, the edge grouting according to the water cement ratio as 2:1, the grouting amount as 2.0l/m ~ 3.0l/m can improve the edge core strength of cement stabilized macadam base by 119 ~ 152%, and the edge grouting can effectively improve the edge collapse of cement stabilized macadam base, making the edge of cement stabilized macadam base straight and beautiful.]()
