Overview

EN 15301-2:2007 is a CEN laboratory method for assessing the shear strength of unbound mineral surfaces used in sports areas. The standard defines a dynamic top-layer test that measures resistance to rotational shear of the surface top layer under controlled laboratory conditions. It is part of the EN 15301 series on surfaces for sports areas and is intended to give reproducible, comparative shear strength data for material selection, quality control and research.

Key topics and technical requirements

  • Scope: Laboratory determination of shear strength by dynamic top-layer testing of unbound mineral sports surfaces.
  • Apparatus: The standard specifies a complete test rig including a test mould with removable base, a steel distribution plate, a compaction device with a drop weight, a shearing disc and alignment gauges, a torque (dynamometric) measuring instrument, a cardan shaft and precision scales. Exact dimensions and tolerances are given in the standard.
  • Specimen preparation:
    • Water content set to 0.7 of the optimum Proctor water content (WOPN) and equilibrated (16 h in a sealed container).
    • Target dry density typically referenced to a proportion (95 %) of the Proctor optimum density over a defined layer thickness.
    • Sample compaction procedure and layer height are prescribed to ensure repeatability.
  • Test procedure:
    • The shearing disc is installed with controlled vertical clearance and aligned using centring and vertical alignment gauges.
    • A starting torsional load equivalent to a specified shear tension (e.g., 50 kN/m²) is applied and maintained, then increased steadily until failure.
    • A minimum of three tests is performed and the mean result reported.
  • Results and reporting:
    • Shear strength is calculated from the maximum torsion moment, disc geometry and pin length; friction losses in bearings are deducted from readings.
    • Test report must include the EN reference, sample identification, shear strength, individual test results (if requested) and any deviations from the procedure.

Applications and users

EN 15301-2:2007 is valuable for:

  • Sports-surface manufacturers and material suppliers for product development and quality control.
  • Independent testing laboratories performing certification and comparative testing of infill and top-layer materials.
  • Sports facility designers and turf/surface specifiers who need objective shear-strength data to inform surface performance, safety and maintenance planning.
  • Researchers studying traction, wear and performance of unbound mineral sports surfaces.
