Basic requirements and price estimation of plastic track materials

Plastic tracks, also known as all-weather track and field surfaces, are made from a combination of polyether, recycled tire rubber, EPDM rubber granules, PU particles, pigments, additives, and fillers. These surfaces offer excellent flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. This makes them ideal for athletes, helping to improve speed, technique, and overall performance while reducing the risk of injuries. The material is composed of polyurethane rubber and other components, providing some elasticity and color, along with resistance to weathering and aging. As a result, it is internationally recognized as the best choice for all-weather outdoor sports flooring.  There are several types of plastic track materials available, each with its own unique characteristics: (a) Breathable plastic tracks are a two-layer system, where the base layer consists of urethane-resin bonded black environmental rubber particles, and the surface layer is made of colored EPDM rubber granules mixed with polyurethane and applied using an SMG machine. They meet GB/14833-93 standards, offer good permeability, and are quick to install. Maintenance is also easier, making them a cost-effective option often chosen by primary schools. (b) Prefabricated plastic tracks are manufactured in a factory as pre-formed rolls. They are made from natural and synthetic rubbers, combined with mineral fillers, stabilizers, and colorants. These are then vulcanized at high temperatures (280–300°C), embossed, and printed. They are commonly used in professional stadiums but are expensive, making them less suitable for most schools. (3) Compound plastic tracks have a base layer made of black environmentally friendly rubber particles bonded with polyurethane resin, and a top layer of colored EPDM rubber particles cast in polyurethane. They offer a balance between durability and cost. (d) Hybrid plastic tracks combine PU and black rubber particles in specific proportions. The mixture is transported to the site, mixed with a catalyst, and then laid and vulcanized at room temperature. The surface layer is the only one that meets national standards and is primarily used in professional competition venues. Both composite and hybrid types fall between breathable and fully synthetic options, offering better performance than breathable tracks but at a higher cost.  When it comes to foundation requirements for plastic tracks: (a) Breathable, compound, and hybrid tracks do not require highly demanding foundations due to their breathability and water resistance. A cement base can be used directly. (2) Prefabricated tracks only need special adhesives provided by the manufacturer. With minimal labor and machinery, the pre-made coils can be laid on a compact base and ready for use after 24 hours. In terms of pricing: 1. Mixed plastic tracks typically cost around $210 per square meter. 2. The cost of a cement base is approximately ¥180 per square meter, while a bitumen base may cost around ¥190. The base thickness is usually about 15 cm. Choosing the right type of plastic track depends on budget, usage frequency, and the level of performance required. Whether it's for a school or a professional stadium, there is a suitable option available to meet different needs.
