Plastic Track Surfacing Terminology Plastic track surfacing has become a popular choice for athletic facilities around the world. It offers a durable and long-lasting surface for athletes to train and compete on. However, with the increasing popularity of plastic track surfacing, there has been a growing need for a standardized set of terminology to describe the various components and characteristics of these surfaces. In this article, we will provide an overview of the most common terms used in plastic track surfacing. 1. Base Layer The base layer is the foundation of the track surface. It is typically made of asphalt or concrete and provides a stable surface for the track to be built upon. The base layer is essential for ensuring the track is level and has proper drainage. 2. Cushion Layer The cushion layer is the layer that provides shock absorption and energy return. It is typically made of rubber and is designed to reduce the impact of running and jumping on the body. The cushion layer is an important component of any track surface as it helps to prevent injuries and improve performance. 3. Wear Layer The wear layer is the top layer of the track surface. It is the layer that comes into contact with athletes' shoes and is designed to provide traction and grip. The wear layer is typically made of polyurethane and is available in a variety of colors. 4. Texture Texture refers to the surface of the track, which can be smooth or textured. Textured tracks offer better grip and traction, which can improve performance and reduce the risk of injury. The texture of a track can be adjusted by adding or removing rubber granules. 5. SBR SBR stands for Styrene-Butadiene Rubber, which is a type of rubber commonly used in plastic track surfacing. SBR is known for its durability and ability to withstand harsh weather conditions. It is also an environmentally friendly option as it is made from recycled tires. 6. EPDM EPDM stands for Ethylene Propylene Diene Monomer, which is a synthetic rubber used in plastic track surfacing. EPDM is known for its UV resistance and color stability, making it a popular choice for outdoor tracks. It is also available in a wide range of colors, allowing for customization of the track surface. 7. Force Reduction Force reduction refers to the amount of shock absorption provided by the track surface. A higher force reduction means that the surface absorbs more shock, reducing the impact on the athlete's body. Force reduction is an important consideration when choosing a track surface as it can impact performance and injury risk. 8. Energy Return Energy return refers to the amount of energy that is returned to the athlete during running and jumping. A higher energy return means that the track surface is more responsive and can improve performance. Energy return is an important consideration for competitive athletes as it can give them a competitive edge. 9. Porosity Porosity refers to the ability of the track surface to allow water to drain through it. A more porous surface allows water to drain quickly, reducing the risk of standing water and improving safety. Porosity is an important consideration for outdoor tracks as it can impact the surface's durability and maintenance requirements. 10. IAAF Certification IAAF certification is a standard set by the International Association of Athletics Federations (IAAF) for track surfaces. IAAF certification ensures that the track surface meets specific performance and safety standards. IAAF certification is important for competitive athletes as it ensures that the track surface meets the highest standards for performance and safety. In conclusion, plastic track surfacing has become a popular choice for athletic facilities around the world. Understanding the terminology associated with plastic track surfacing is essential for selecting the right surface for your needs. By understanding the components and characteristics of plastic track surfacing, you can make an informed decision that will provide a safe and durable surface for athletes to train and compete on.
