Abstract
In recent years, large forklifts with heavy wheel load are increasingly introduced to the freight container yard. In the current design of freight container yard pavement, theoretical design method based on multi-layered elastic analysis is applied. However in the case of freight container yard, wheel loads of forklifts are significantly larger than the traffic loads on the roads. To investigate the deformation characteristics of asphalt pavement under heavy wheel load, moving wheel loading tests were carried out On the other hand, ground contact area of forklift tires change with carrying containers. Because the tread of forklift tire is greater than the thickness of pavement, strain in the pavement is significantly influenced by ground contact area. In this study, FEM was introduced to estimate the effect of ground contact area on the strain in the asphalt pavement
