Researches on how to add the high strength synthetic fibers in the pavement concrete at the airport to improve its performance, and the impact resistance improvement of the high strength synthetic fibers at the airport pavement joints. The restructured concrete pavement rut testing machine is adopted to take the wheeled impact test in the study. Moreover, the shedding concrete quantity is used to measure the degree of injury. The test specimens are divided into two groups, i.e. specimens without staggered steps and with staggered steps. The actual situation of the airport pavement joint is simulated. The results show that as for the two test groups, an increase in the number of impact load will cause the increase of concrete weight loss. As for the specimens without staggered steps, after 1 000 times of impact, the amount of shedding concrete dropped by 1.4 kg/m3 is 51.1% lower than that of ordinary concrete. For the specimens with staggered steps, the concrete shedding decreases by 73.3%, 72.5%, and 46.6% respectively with the increase of fiber content to 1.4 kg/m3. The result shows that the increase of the synthetic fiber content can effectively reduce the shedding quantity of the joint angle and the angle at staggered steps, and the improvement effect is more and more obvious.
