Abstract
Abstract A substitute ground surface material comprising sand coated or treated with a binder comprising a free flowing extender oil with a viscosity transition below -5°F, with a synthetic polymeric material such as styrene-butadiene-styrene co-polymer dissolved or dispersed in the oil. The binder comprises approximately 2% of the material which is an inert, discreet material permanently capable of being raked when laid in a layer upon a substrate. The material is laid on a suitable porous base to form a sports surface for a horse running track or the like.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
57 words
A substitute ground surface material comprising sand or similar particulate or granular material treated with a binder comprising an extender oil having a polymeric material dissolved or dispersed therein, the oil being free flowing at ambient temperatures so as to produce an inert discrete material capable of being raked when laid in a layer upon a substrate.
Claim 2
Dependent Claim
57 words
A substitute ground surface material comprising sand or similar particulate or granular material treated with a binder comprising an extender oil having a polymeric material dissolved or dispersed therein, the oil being free flowing at ambient temperatures so as to produce an inert discrete material capable of being raked when laid in a layer upon a substrate.
Claim 3
Dependent Claim
