Abstract: A track for equestrian sports and the like, comprising a base layer of compacted polymeric particles, the majority of which have a size in the range from 20–60 mm, an intermediate layer overlying the base layer and comprising compacted polymeric granules whose mean particle size is in a range from 3–25 mm and a top layer comprising finely divided composite particles formed from a thermoplastic polymer, a finely divided filler material such as sand and a wax-based binder. The invention also provides a method of making a particulate material which comprises blending a polymer-coated finely divided filler material with wax and a particulate elastomer, in the presence of an organic solvent.
