Abstract：
: 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 280kg/m3, the appropriate air-containing is 3%~5% for the cold region pavement concrete.
