The present study was conducted to investigate impact buffer property of a recently developed water penetration and retentive pavement for groundwork of artificial turf playground. Three balls with different weight and diameter were thrown down from 70cm height to three different groundworks of the artificial turf to evaluate the impact force and the coefficient of restitution. The groundworks were composed of two different hardness of water penetration (60 and 100%) and asphalt. The results obtained in the present study were as follows ; 1) The impact force of the asphalt groundworks was significantly higher than the water penetration and retentive clay pavements with different hardness of water penetration. 2) The coefficient of restitution of the asphalt groundwork was the highest among three groundworks. The clay pavement with 100% hardness was significantly higher than that with 60%.
