| 摘 要： | 低等级旧路宜采用单侧加宽而高等级公路采用双侧加宽更加有利。加宽路基施工中选择良好填料,做好基地处理,提高压实度,充分利用试验路资料,有利于减少新旧路基的不均匀沉降。加宽部分路面的施工应在充分调查了解旧路面现状的基础上进行,施工中可以在接缝处设置土工织物来减少路面裂缝的出现。

| Abstract: | One side widening is suitable for low-grade road and double side widening is suitable for high-grade road.During the construction,choosing better filler,deposing foundation better,improving new roadbed compaction and making use of test section data are benefit for reducing different settlement between new subgrade and old one.New pavement construction plan should be done based on the good investigation of old pavement,and soil geotextile could be used to reduce pavement cracks. |
