Abstract
The function of shock absorbed about artifical sand grass were examined to elasticity by the method of analysis to impact wave on human body about the 18 different species of pavement. It is concluded. The thick surface course material show the more effective function of shock absorbed. But surface course material is more effective than layer course materials, and there is not effect of bedrock materials. Good function of shock absorbed like the truf are granular rubber with polypropylene net and blister urethane mat.
