| 摘 要： | 改性乳化沥青混凝土是一种新型改性材料,加入水泥后,其各种力学性能优于普通乳化沥青和热沥青。通过静三轴试验、蠕变试验、渗透试验,研究水泥-改性乳化沥青混凝土在大坝心墙防渗方面的性能,其抗剪强度、变形特性、抗渗性能等满足规范要求,并具有污染低、抗渗好等优点,表明其应用于大坝心墙防渗是可行的。

| Abstract: | With cement added in,the mechanical properties of modified asphalt emulsion concrete,a new type of modified material,are superior to ordinary asphalt emulsion and hot asphalt.According to the static triaxial test,creep testing and penetration test,the research on performance of the dam impervious core with cement emulsified asphalt concrete is discussed.The analyses of tests and calculation show its shear strength,deformation characteristics,impermeability meet standard requirements,with low pollution,superior seepage prevention performance,and could be applied to the dam impervious core. |
