| 摘 要： | 针对我国寒冷地区机场道面混凝土受冻融循环破坏造成耐久性不良的现象,通过快冻法进行了道面混凝土的冻融循环试验,以及冻融前后强度、动弹性模量和质量损失的对比分析。结果表明:冻融循环对道面混凝土抗折强度影响较明显,掺引气减水剂的道面混凝土可提高抗冻抗渗性,改善耐久性,可应用于寒冷地区的机场道面工程。

| Abstract: | For poor durability of airport pavement concrete in cold areas due to freeze-thaw damage,freeze-thaw cycle test is carried out on pavement concrete through fast freezing method,and the strength,dynamic modulus of elasticity and quality loss are compared before and after freezing.The result shows that freeze-thaw cycle has significant influence on rupture strength of pavement concrete.The concrete mixing with air-entraining and water-reducing agent will be improved frost resistance and impermeability,and thus its durability will be improved,which can be applied to airport pavement engineering in cold areas. |

| Keywords: | airport pavement concrete freeze-thaw cycle test durability air-entraining and water-reducing mixture strength |
