In order to solve the problem that the cement concrete of the airport pavement is easy to produce early micro cracks during the construction period and bring potential safety hazards to the aircraft operation during the service period, this study proposed a method to strengthen the surface performance of the airport pavement by laying fiber mesh in the concrete surface mortar layer. Carbon fiber, aramid fiber and basalt fiber mesh were selected as reinforcement materials to characterize the early cracking resistance of concrete with the early cracking performance of mortar. The effects of water cement ratio, cement sand ratio, fineness modulus and fiber mesh on the early cracking resistance of cement mortar in high temperature and multi wind simulation environment were studied. The results show that the early cracking resistance of cement mortar is the best when the water cement ratio is 0.43, the cement sand ratio is 0.47 and the fineness modulus is 3.4, and when the fiber mesh is basalt fiber with a grid size of 3 mm ×3 mm, the strengthening effect of early cracking resistance is the best.
