| 摘 要： | 介绍沥青路面浅层注浆加固基层及新旧路基结合部预埋柔性管两种注浆新技术，提出其适用范围、施工工艺及注浆效果的检验。对比分析注浆检测结果表明:对水泥路面注浆能很好地治理路面面板脱空，沥青路面基层补强注浆能提高沥青路面基层的整体强度，在新旧路基结合部预埋柔性管注浆能显著降低路基的差异沉降。

| Abstract: | Two new technologies of shallow grouting on asphalt pavement for subgrade reinforcement and embedding flexible pipe in the junction between new and old roadbeds are introduced in this paper.Then their application scope,construction process and grouting effect inspection are separately put forward.Through comparison of grouting results,it is shown that grouting on cement pavement can better prevent hollowing of cement slab;grouting on asphalt pavement can improve the overall strength of subgrade;embedding fl... |
