Plastic track is a sports field material that has been widely used in schools, gymnasiums, parks and other places in recent years. It has the advantages of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which is conducive to the exertion of athletes' speed and technique, effectively improves sports performance, and reduces the rate of fall injury.
According to the construction structure, materials and uses of plastic runways, they can be divided into the following types:
1. Mixed plastic runway
The hybrid plastic runway, also known as the traditional runway, is a flat and dense structure. The surface layer is composed of polyurethane, rubber particles, pigments and other materials, and the bottom layer is composed of cement, asphalt and other materials. The hybrid plastic runway has good abrasion resistance, compressive strength and elasticity, but its air permeability is poor and it is prone to water accumulation in the rainy season.
2. Breathable plastic runway
Breathable plastic runway, also known as permeable runway, is widely adopted in rainy areas because of its good air permeability and water permeability. The surface layer is composed of polyurethane, rubber particles, pigments and other materials, and the bottom layer is composed of polyurethane, rubber particles, sand and other materials. The breathable plastic runway has good abrasion resistance, compressive strength and elasticity, and has good air permeability and is not easy to accumulate water.
3. Composite plastic runway
The composite plastic runway is a combination of a hybrid plastic runway and a breathable plastic runway, which has the advantages of both. The surface layer is composed of polyurethane, rubber particles, pigments and other materials, and the bottom layer is composed of polyurethane, rubber particles, sand, asphalt and other materials. The composite plastic runway has good wear resistance, compressive strength, elasticity and air permeability.
Fourth, the all-plastic plastic runway
The all-plastic plastic runway replaces the rubber particle filler with plastic particles, thereby improving the wear resistance and impact resistance of the runway. It is mainly composed of two parts: polyurethane elastic layer and plastic particles. The all-plastic plastic runway has good elasticity, wear resistance and impact resistance, but the cost is high.
In practical applications, the appropriate type of plastic runway can be selected according to different site conditions and needs. For example, in professional competition venues, mixed plastic tracks or composite plastic tracks are generally usedIn schools, parks and other places, breathable plastic runways or all-plastic plastic runways are generally used.
