摘　　要：文章通过抗渗、冻融、化学侵蚀试验及现场摩擦系数测试,研究了涂刷两种新型混凝土保护剂进行表面防水处理对机场混凝土道面耐久性的影响。结果表明:两种混凝土保护剂均能大幅改善混凝土的抗渗性能,降低混凝土冻融后的动弹性模量损失以及道面除冰液侵蚀下的强度损失,且不影响道面的抗滑性能。通过涂刷新型混凝土保护剂进行表面防水处理是提高混凝土道面耐久性的有效方法。Through tests on impermeability,freeze thawing,chemical attack and on field friction factor,the article studied the impact of using two new concrete protective agents to perform surface waterproofing treatment on the durability of airport concrete pavement.The result shows that these two agents can improve the impermeability of concrete,decrease the loss of dynamic modulus of elasticity after freeze thawing and the loss of strength after corrosion caused by deicing fluid.It does not affect the anti-resistance of pavement.It is proved that using the new concrete protective agent to perform surface waterproofing treat-ment is an efficient way to improve the durability of concrete pavement
