摘要
分析了高速公路涵洞段路面波浪形的施工原因，并通过揭普高速公路揭阳互通立交的工程实践，从材料选择、松铺厚度及夯压工艺等方面探讨了涵背回填砂的施工控制方法，以保证路基工程质量。
The reasons caused the undulate pavement in culvert part of expressway are analyzed. In this paper combined with practical interchange work in Jiepu expressway, from material selection, slackly lay thickness, compaction construction and other aspects the construction method of sand filled behind bridge and culvert is introduced in order to ensure engineering quality of roadbed.
