旁多工程沥青混凝土配合比及施工技术研究

Study on mix proportion and construction technology of asphalt concrete in Pangduo hydro project

西藏旁多水利枢纽工程地处高海拔多震地区,工程采用沥青混凝土作为大坝防渗体,为了保证其施工质量,施工前完成了沥青混凝土配合比选择、碾压参数选择以及低温施工技术研究工作。

The Tibet Pangduo hydro projecct is loacted at the high-altitude and multi-shock region, the asphalt concrete is used as the dam impervious body. In order to ensure the quality of construction, the selection work of asphalt concrete mix proportion and the construction test of asphalt concrete rolling parameters have been completed before construction. Based on the above works, the research of low-temperature construction satified actual project has been completed.
