Steel and basalt hybrid fibers reinforced concrete technical route was proposed，through the freeze-thaw test， the influence of steel fiber mixed basalt fiber on the frost-resistance of concrete and freeze-thaw model were studied． The results showed that different fiber dosage had great influence on the frost-resistance of concrete，and when the volume fraction of steel fiber was 1. 5% and basalt fiber was 0. 05%，the frost-resistance of airport pavement concrete attain the level of F250． The freeze-thaw damage mechanism was analyzed，freeze-thaw damage models of hybrid fiber concrete were established by using relative dynamic modulus of elasticity and accumulative freeze-thaw damage，the model based on relative dynamic modulus of elasticity attenuation was superior to the one based on accumulative freezethaw damage，and quadratic function model had a higher fit accuracy as compared to exponential function model．
