CEN/TC 217/WG 4 - Unbound mineral surfaces

This part of EN 15301 specifies a method for determining the shear strength by dynamic top layer testing of unbound mineral surfaces in the laboratory.

This part of EN 15301 specifies methods for determining the rotational resistance of sports surfaces.

This European Standard specifies a method for the determination of the water content of unbound mineral surfaces used for outdoor sports areas.

This European Standard describes two methods for determining the thickness of granular materials within a structure.
The two methods can be used to provide an indication of the thickness of surfacing material, one using a steel tape, the other using a floating disc and a steel tape. Method 1 is applicable to layers within a profile. Method 2 measures the thickness of a material at the surface.

This European Standard specifies a method for determining the composition and particle shape of unbound minerals for outdoor sports surfaces.

This European Standard specifies a method for the determination of water absorption of unbound minerals (grain size till 6 mm) for outdoor sports surfaces.

This European Standard specifies a method for the determination of hardness of natural turf and unbound mineral surfaces.

This European standard specifies methods for determining the shear strength of natural turf, synthetic turf and unbound mineral sports surfaces.
Method 1 is intended to be carried out on site. Method 2 is intended to be carried out in the laboratory but is applicable only to unbound mineral sports surfaces.
