ABSTRACT:
An outdoor surface composition for surfacing outdoor playing areas or other utility areas comprises a mixture of particulate reclaimed rubber and inorganic particulate solids, such as sand, mixed together and compacted in a particular weight ratio, with each of the components having a designated particle size range. The amount and particle size range of both the reclaimed rubber and the inorganic particulate solids are important in obtaining a composition which is water-pervious for adequate drainage, shock absorbent, resistant to shear under average athletic playing conditions, and compaction resistant. For some applications, organic particulate solids, such as wood chips, peat, manure or cinders, may be included with the composition.
