Abstract:For poor durability of airport pavement concrete due to freeze-thaw damage,the experimental study on frost resistence of basalt fiber reinforced concrete for airport pavement were carried out in laboratory,0.1% volume fraction mixing amount of two size basalt fiber were mixed into airport pavement concrete,and freeze-thaw cycle test is carried out on pavement concrete through fast freezing method, the dynamic modulus of elasticity, quality loss and the surface condition of concrete were compared before and after freezing.The result shows that the concrete mixing with basalt fiber will be obviously improved frost resistance,the level of frost resistence increased 2.7 to 3.3 times.The frost resistence of pavement cocrete mixing with 0.1% volume fraction mix amount of the basalt fiber of length 20mm,diameter 20μm will reach the best.
