ABSTRACT:
A playing field surface is formed of a synthetic fiber carpet, having generally upright pile fibers, upon which is applied a particulate covering. The covering is formed of a lower layer of resilient, rubber-like particles such as crumb rubber, and an upper layer of relatively coarse sand-like particles. A binder material may be used for binding together at least some of the rubber-like particles. The upper layer sand-like particles cooperate with the exposed upper end portions of the fibers to provide a simulated grass-like field surface. The relatively large sand-like particles resist excessive compacting of the covering as well as form a stabilizing cover for the layer of rubber-like particles which provide an inner resiliency to the field surface.
