Abstract
Concrete pavement is easy to crack and generate the chunks, which may destroy the engine of the airplane and maintenance cost is very expensive. Engineered cementitious composites (ECC) is ductile with microcracks, but its strength is low. Glass Fiber Reinforced Polymer (GFRP) mesh imbedded in ECC could improve the strength. This paper investigates the impact fatigue behaviour of ECC and GFRP mesh reinforced ECC under 5 different impact pressures (1.61 MPa, 1.88 MPa, 2.10 MPa, 2.41 MPa and 3.60 MPa), the concrete specimens were also tested for comparison. The pulse velocity through the specimens was also tested to analyse the damage of the specimens. The experimental results show that GFRP mesh reinforced ECC has improved impact fatigue behaviour than ECC specimens. The concrete specimens were all broken after a few impacts, but the GFRP mesh reinforced ECC specimens were all not broken after impacted for 30000 times. The impact fatigue behaviour of ECC reinforced with two layers of GFRP mesh with a grid dimension of 10 mm was the best, which is a desirable pavement composite comparing to the ordinary concrete and ECC without reinforcements.

Summary
Concrete is an important runway pavement material, but it is easy to crack and generate the chunks [1,2]. Glass Fiber Reinforced Polymer (GFRP) mesh has been used as the reinforcement embedded in the concrete to improve the strength of the concrete in recent years [5]. Impact fatigue behavior is important for the runway pavement, because the runway pavement has to carry the cyclic impact pressure in the design life of 30 years [6]. There is no research about the impact fatigue behavior of the runway pavement [7,8,9]. This paper presents an experimental program to characterize the impact fatigue behavior of ECC with/without GFRP mesh reinforcements with different grid sizes. The ordinary concrete specimens with the same compressive strength as the ECC specimens were investigated. The pulse velocity through the specimens was tested to analyse the effect of the impact times and the impact pressure on the damage of the specimens
