摘　　要：针对我国北方寒冷地区机场道面混凝土存在耐久性不良的现象,通过掺加引气减水剂配制高性能道面混凝土,研究了含气量对道面混凝土和易性、抗折强度、抗冻性能及耐磨性能的影响,提出了寒冷地区道面混凝土最大水灰比为0.45、最小水泥用量为280kg/m3、含气量范围为3%～5%。For the bad durability phenomenon of airport pavement concrete on north cold region,influence of air-containing on placeability,flexural strength,freeze resistence and abrasion resistance was studied base on high performance pavement mixed with superplasticizer and air-entraining agent.Put forward the maximum water-cement ratio is 0.45,the minimum cement quantity is 280 kg/m3,the appropriate air-containing is 3-5% for the cold region pavement concrete.
