In the durability experiment of the surface crack resistance, the impermeability, the abrasion resistance and frost resistance of high-strength FC synthetic fiber reinforced pavement concrete, the study explores its ruling law and functioning mechanism. The result shows that the FC fiber can markedly improve the durability of airport pavement concrete. The improvement varies according to the variation in the addition amount of FC fiber. When the amount rests approximately 1.2 kg/m3, the durability is optimal.
