A construction method of high elasticity pavement materials for a playground using a shock-absorbing rubber mat is provided to protect children from getting injured to the minimum and to prevent secondary accidents by absorbing impact energy. A construction method of high elasticity pavement materials for a playground using a shock-absorbing rubber mat comprises the steps of spreading a rubble layer(4) on the in-situ ground(5), paving a water-permeable base layer(3) made of waste tire and aggregate, a concrete layer or an asphalt layer on the rubble layer, installing a shock-absorbing rubble mat(10) and paving an auxiliary elastic layer(2), and then finishing up with an elastic surface layer(1). Hereon the auxiliary elastic layer is formed by mixing rubber chips having the size of 2~15 millimeters with polyurethane binder to have elasticity and the elastic surface layer is formed by mixing rubber chips having the size of 2~6 millimeters with polyurethane to have elasticity. |
