摘要
通过简述我国某水电站工程上水库沥青混凝土防渗面板开裂漏水 ,及对有关沥青的检验指标分析对比 ,说明“碾压式沥青混凝土面板防渗技术”课题的水工沥青技术指标并结合将要开工的两个抽水蓄能电站上、下水库沥青混凝土防渗面板的运行要求 ,对沥青的针入度、软化点、延度、蜡含量等指标 ,特别是低温延度等指标 ,进行分析说明 。
Based on the cracking of watertight asphalt-concrete facing slab which occurred to the upper reservoir of a certain domestic hydropower plant and the analyses of test indexes, the research on watertight technology for rolled asphalt-concrete facing slab was described. In addition, some performance indexes of asphalt including penetration, softening point, ductility and wax content were analyzed in terms of the requirements of the upper and lower reservoirs of two pumped storage hydropower plants which are being put into use.
