Plastic tracks, also known as all-weather track and field surfaces, are made from a combination of polyether, recycled tire rubber, EPDM rubber particles, PU particles, pigments, additives, and fillers. These tracks offer excellent flatness, high compressive strength, the right balance of hardness and elasticity, and stable physical properties. This makes them ideal for athletes, helping improve their speed and technique while reducing the risk of injuries. The material is composed of polyurethane rubber and other components, offering some elasticity, color options, and resistance to weathering and aging. As a result, it is widely recognized as the best all-weather outdoor flooring solution globally.
There are several types of plastic track materials available:
(a) **Breathable plastic tracks** are a two-layer system. The base layer is made of urethane-resin-bonded black environmental rubber particles, while the top layer consists of colored EPDM rubber particles mixed with polyurethane and sprayed directly onto the surface using an SMG machine. These tracks meet GB/14833-93 standards, offer good permeability, are quick to install, and easier to maintain. They are cost-effective and often chosen by primary schools.
(b) **Prefabricated plastic tracks** are manufactured in coils in the factory. They are made from natural and synthetic rubber, combined with mineral fillers, stabilizers, and colorants, then vulcanized at high temperatures (280–300°C). They are embossed and printed uniformly. These are commonly used in professional stadiums but are too expensive for most schools.
(c) **Compound plastic tracks** have a base layer of black environmentally friendly rubber particles bonded with polyurethane resin, and a top layer of colored EPDM rubber particles cast in polyurethane resin.
(d) **Hybrid plastic tracks** combine PU and black rubber particles in a specific ratio. The materials are transported to the site, mixed, and vulcanized at room temperature. They are the only type with national standards and are mainly used in professional competition venues. Both compound and hybrid tracks fall between breathable and full plastic tracks in terms of performance and cost, with higher installation requirements.
When it comes to foundation requirements:
(a) Breathable, compound, and hybrid tracks do not require a very strong foundation due to their breathability and water resistance, allowing direct use of cement bases.
(b) Prefabricated tracks only need special adhesives and can be laid on a compact base with minimal labor and machinery. After 24 hours, they are ready for normal use.
Regarding pricing:
1. The price of mixed plastic tracks is generally around 210 yuan per square meter.
2. The cost of a cement base is approximately 180 yuan, while a bitumen base costs about 190 yuan. The base thickness is typically around 15 centimeters.
Whether you're building a school track or a professional stadium, choosing the right type of plastic track depends on your budget, usage needs, and long-term maintenance considerations.
