In present paper, the numerical simulation is conducted to investigate the dynamic response of the composited pavement system under multiple drop weight impact loads. This composited pavement system consists of asphalt concrete (AC) layer reinforced with geogrid (GST), followed by high strength concrete (HSC) layer, and then engineered cementitious composites (ECC) layer, taking into account their relative advantages in terms of strength and relative ductility. Actual measurements from the laboratory test are used as a validation for the results of the numerical simulation. It is shown that the numerical results and laboratory measurements from two times of impact tests are in great accordance in terms of damage pattern, crater diameter, and potentiometer readings. This calibrated model from numerical simulation could then be further used to investigate the factors that might enhance the impact resistance of the composited pavement system subject to various levels of impact loads.
