摘　　要：针对我国寒冷地区机场道面混凝土以及一些高等级公路路面混凝土耐久性不良的现象,在分析其原因的基础上提出了相应的防治措施,对不同类型的道面混凝土的耐久性进行对比试验研究。试验结果表明:掺加粉煤灰或引气减水剂的道面混凝土,其抗冻、抗渗、耐磨性能均有较大提升,为高性能道面混凝土。In view of the bad durability phenomenon of airport pavement concrete and some concrete highways in cold region of our country, on the basis of analyzing the causes of the bad durability phenomenon, then put forward relevant measures to prevent the bad durability phenomenon, and studies the durability of different kinds of pavement concrete through compare experiments.The results suggest that pavement concrete mixed with fly ash or air-entraining and water-reducing agent both have better fi＇eeze proof anti-permeabilily and abrasion resistance performance, both are high performance pavement concrete.
