This adapted test method covers the determination of strength and stress-strain relationships of a cylindrical specimen of a compacted, drained cohesive natural or synthetic soil surface used in equine sports surfaces. Specimens are isotropically consolidated and sheared in compression at a constant rate of axial deformation (strain controlled).

The shear strength of an equine sports surface material describes the resistance of the material to sliding of the surface layers. Shear strength influences both slide and penetration of the hoof in the track surface. It is generally accepted that a small amount of slide on impact is desirable [1-3]. However, the surface must have sufficient shear strength to support the horse during propulsion [1-5]. Thus, an optimal shear strength would be expected for an equestrian surface.
