A CONSTRUCTION PROCESS OF ELASTIC SAND LAYER FOR PLAYGROUND

摘要

PURPOSE: A construction method of an elasticity sand layer for a playground is provided to maintain the drainage and impact absorption capacity of the sands. CONSTITUTION: A base layer is formed on the ground. The mixture which is mixed with waste rubber chips, in which diameter is 5~25mm, 90~97 weight% and binder resin 3~10 weight% is spread on the base layer in the thickness of 80~200mm. An elastic rubber layer is formed on the base layer. A non-woven fabric is covered on the elastic rubber layer. The sand of 200~500mm is covered on the non-woven layer in order to form a sand layer.
