While poured-in-place playground surfacing is a very promising form of playground surface construction, its use has not been without problems. In order to address these issues, ASTM International Committee F08 on Sports Equipment and Facilities has developed F 2479, Guide for Specification, Purchase, Installation and Maintenance of Poured-in-Place Playground Surfacing. F 2479 is under the…
