| 中文摘要: |
| 本文对国内当前沥青混凝土防渗技术发展中的热点问题进行了评述和分析，包括施工质量控制的关键问题、孔隙率控制中的马歇尔试件击实标准问题、低温抗裂和高温斜坡稳定的判定问题以及柔性试验标准问题。在沥青混凝土应用于高坝建设方面，提出应加强心墙与坝体相互作用设计、沥青混凝土本构关系、沥青混凝土抗渗机理、水力劈裂和自愈机理等问题的研究。沥青混凝土衬砌防渗在我国寒冷地区渠道中具有相当的技术优势，本文提出了应予关注的问题。 |
| 英文摘要: |
| The important topics in development of asphalt concrete technology in China at present are summarized. The topics include the quality control in construction, compaction standard of Marshall Specimen for porosity inspection, evaluation of low temperature fracturing and high temperature slope stability as well as the flexibility test method. In view of high embankment dams with asphalt concrete core wall are being more and more constructed, further study are suggested such as interaction between transition zone and core, constitutive relationship of aslohalt concrete, imperviousness mechanism, hydraulic fracturing and self healing characteristics, etc.. Besides, the application of asphalt concrete to seepage prevention of canal lining in cold region of China is proposed. |
