就地冷再生技术在219省道路面维修中的应用

On application of regeneration technique on the spot cooling in roadbed maintenance of 219 provincial road

结合省道219线五溪至九华山段路面维修工程,对冷再生基层施工工艺及其质量控制进行了探讨,为冷再生基层在池州市的推广应用提供参考经验,工程实践证明,旧路面就地冷再生技术具有成本低、工期短、节约材料、不损坏路基、消除污染保护环境、交通安全等特点,对于节约自然资源,保护生态环境具有极大的意义。

Combining with the roadbed maintenance project of Wuxi to Jiuhuashan section along 219 provincial road, the paper explores the construction craft and the quality control of the cooling regeneration technique, provides the reference experience for extending the application of the cooling regeneration basic layer in Chizhou city, and proves the regeneration technique on the spot cooling has some features, including the low costs, short constructing period, the saving of materials, undamaged roadbed, the elimination of pollution and protection of environment, and traffic safety, so it is significant for saving natural resources and protecting ecological environment.
