In the previous study, we examined about a structural design method of pedestrianized pavement in consideration of users' comfort and safety. In this study, we found a meaningful relationship between impact acceleration to be measured by the road hardness test and surface modulus of elasticity (EPFWD) to be measured by the portable FWD test, and that it was possible for a structure design with the surface modulus by using the Burmister's solution for two-layered elasticity model.
The objective of this study is to verify a meaningful correlation between the height of safety fall to be measured by the HIC test and surface modulus of elasticity (EPFWD) and we examined a surface layer thickness method of consideration of safety for the fall from playground equipment. In addition, this study is to verify the meaningful correlation among the HIC test, the road hardness test and simple bearing capacity test and confirmed that it was possible to alternate with two other test devices for the height of safety fall which was controlled by conducting HIC test.
