Standard Specification for Synthetic Surfaced Running Tracks

ABSTRACT
This specification establishes the minimum performance requirements, classification, and test methods for synthetic surfaced running tracks. Even so, this specification does not imply that an injury cannot be incurred if the surface is found to be in compliance with this specification. The requirements for which newly installed synthetic surfaces shall be tested on and consequently comply to are imperfections, evenness, thickness, drainage, force reduction, modified vertical deformation, texture influence when wet, tensile properties, color in grey scale, weathering, spike resistance, and flammability.
SCOPE
1.1 This specification establishes the minimum performance requirements and classification when tested in accordance with the procedures outlined within this specification. All documents referencing this specification must include classification required.  
1.2 This specification does not imply that an injury cannot be incurred if the surface is found to be in compliance with this specification.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM F2157-09(2018), Standard Specification for Synthetic Surfaced Running Tracks, is an internationally recognized standard developed by ASTM International for the quality and performance of synthetic running track surfaces. This specification addresses minimum performance requirements, testing procedures, and classification criteria to ensure safety, durability, and suitability for athletic competition and training. By providing clear guidelines for installation and material selection, ASTM F2157 supports the construction and maintenance of high-quality running facilities suitable for athletes of all levels.

Key Topics

  • Performance Requirements: The standard sets criteria for surface imperfections, evenness, thickness, drainage, force reduction, vertical deformation, tensile properties, surface color, weathering, spike resistance, and flammability to ensure a safe and high-performing track.

  • Test Methods: Guidance is provided on laboratory and on-site testing for compliance, including procedures for measuring surface friction, composition, thickness, and performance under environmental stress.

  • Track Classification: Tracks are assigned classifications (A, B, or C), with "A" representing the highest performance and safety criteria. Classification depends on full compliance with all relevant requirements.

  • Material Specifications: Requirements for materials such as EPDM and SBR rubber, binders, coatings, and construction layers are defined. Standards ensure surfaces are free from contaminants and structurally suitable for sustained athletic use.

Applications

The practical value of ASTM F2157 is realized in a wide range of applications, including:

  • Track & Field Facility Construction: Contractors, architects, and facility managers use the standard to guide the design and installation of synthetic running tracks for schools, universities, and stadiums.

  • Product Development and Procurement: Manufacturers of track surfacing products refer to this specification to meet industry benchmarks and ensure their products will perform reliably in the field.

  • Maintenance and Safety Inspections: Facility operators use the standard's classification and testing criteria to evaluate surface wear and schedule maintenance or resurfacing, thereby extending the track's lifecycle and enhancing athlete safety.

  • Regulatory and Competitive Requirements: Many sports governing bodies and public procurement processes require compliance with ASTM F2157 as a precondition for competition-level performance and public safety assurance.

Related Standards

For comprehensive track surfacing solutions and performance validation, reference the following related standards:

  • ASTM D297: Test Methods for Rubber Products - Chemical Analysis
  • ASTM D2859: Test Method for Ignition Characteristics of Finished Textile Floor Covering Materials
  • ASTM D2616: Test Method for Evaluation of Visual Color Difference With a Gray Scale
  • ASTM E303: Test Method for Measuring Surface Frictional Properties Using the British Pendulum Tester
  • ASTM E1131: Test Method for Compositional Analysis by Thermogravimetry
  • DIN 18035 Part 6: Standards for Sports Grounds, Synthetic Surfacings (Germany)
  • IAAF Performance Specifications: For synthetic surfaces in athletic tracks (international athletics standard)

Conclusion

Implementing ASTM F2157-09(2018) ensures that synthetic running tracks are safe, resilient, and capable of withstanding demanding use and environmental conditions. Compliance with this standard provides confidence for athletes, facility owners, and regulatory bodies, supporting performance excellence and long-term value in athletic track construction and maintenance. For optimal results, always align your track surfacing project with ASTM F2157 and relevant related standards.
