科特迪瓦西部地区公路改造项目(一期)冷再生施工技术总结

Summary of Cold Recycling Construction Technology of Highway Reconstruction Project (Phase Ⅰ) in Western C■te d’Ivoire

由于西非地区地质条件、气候环境的特殊性,科特迪瓦地区的水泥就地冷再生施工没有成熟的经验可循。科特迪瓦西部地区公路改造项目(一期)项目部通过100 m的试验段施工,验证水泥就地冷再生的施工工艺、设备及人员配置、混合料水泥掺量及质量控制要点等方面,尤其是对单钢轮压路机的选用、水泥掺量确定2项重点进行验证总结,从而对后续正式施工提供经验和理论依据。

There is no mature experience to follow in the construction of cement on-site cold recycling in C■te d’Ivoire due to the special geological conditions and climatic environment in West Africa.To verify the construction technology,resource allocation,the mixing quantity of cement and the key points of quality control,the project department of Western C■te d’Ivoire Highway Reconstruction Project(Phase I) carried out 100m test section,especially for single drum roller,and the mixing quantity of cement.So as to provide empirical and theoretical basis for subsequent formal construction.
