高速路路基拓宽新老路搭接技术探究

摘要

The oaoer analyzes new-old road connection oroblems in highway subgrade widening from two asoects of construction and cracks,ex-olores construction technology ooints of soil subgrade,rock-filling subgrade and earth-rock-filling subgrade,and summarizes factors influencing subgrade comoaction,which has orovided some guidance for new-old subgrade connection.%从施工和裂缝方面分析了高速公路路基拓宽新老路搭接存在的问题，探讨了土质路基、填石路基及土石混填路基的施工技术要点，总结了影响路基压实的因素，为今后新老路基的搭接提供了参考借鉴。
