Introduction
Plastic track is a type of athletic surface that is commonly used in sports fields and tracks. It is made of a mixture of synthetic materials that are designed to provide a durable, long-lasting surface that can withstand the wear and tear of heavy use. The surface layer of a plastic track is an essential component of the overall structure, as it provides the necessary grip and cushioning for athletes to perform at their best. This article will explore the construction process of the surface layer of a plastic track, including the materials used, the installation process, and the benefits of this type of surface.
Materials Used in the Surface Layer of a Plastic Track
The surface layer of a plastic track is typically made of a mixture of granulated rubber and polyurethane. The rubber is sourced from recycled tires and is ground into small particles. The polyurethane is a synthetic material that is added to the rubber to create a binding agent. The mixture is then poured onto the track surface and spread evenly to create a smooth, level surface.
The rubber used in the surface layer of a plastic track is an essential component of the overall structure. It provides the necessary grip and traction for athletes to run, jump, and perform other athletic movements. The rubber also absorbs shock and impact, reducing the risk of injury to athletes. Additionally, the use of recycled rubber in the surface layer of a plastic track is an environmentally friendly option that reduces waste and promotes sustainability.
The polyurethane used in the surface layer of a plastic track is a vital component of the overall structure. It acts as a binding agent, holding the rubber particles together and creating a durable, long-lasting surface. The polyurethane also provides a smooth, level surface that is ideal for athletic performance.
Installation Process of the Surface Layer of a Plastic TrackNG体育·南宫官方网站
The installation process of the surface layer of a plastic track is a complex and time-consuming process that requires specialized equipment and expertise. The following are the steps involved in the installation process:
1. Site Preparation: The site must be cleared of any debris or obstacles that may interfere with the installation process. The ground must also be leveled and compacted to ensure a smooth, even surface.
2. Base Layer Installation: A base layer of asphalt or concrete is installed to provide a stable foundation for the surface layer. The base layer must be allowed to cure for several days before the surface layer can be installed.
3. Surface Layer Installation: The surface layer is installed by pouring the rubber and polyurethane mixture onto the track surface and spreading it evenly with a specialized machine. The surface layer must be allowed to cure for several days before it can be used.
4. Line Marking: Once the surface layer has cured, line markings are added to the track to indicate the lanes, start lines, and other necessary markings.
Benefits of a Plastic Track Surface
There are several benefits to using a plastic track surface, including:
1. Durability: Plastic track surfaces are designed to be durable and long-lasting, with a lifespan of up to 15 years.
2. Safety: The rubber and polyurethane mixture used in the surface layer of a plastic track provides a cushioned surface that reduces the risk of injury to athletes.
3. Performance: The surface layer of a plastic track provides the necessary grip and traction for athletes to perform at their best.
4. Maintenance: Plastic track surfaces require minimal maintenance, with only occasional cleaning and repairs needed.
Conclusion
The surface layer of a plastic track is a vital component of the overall structure, providing the necessary grip, cushioning, and durability for athletes to perform at their best. The use of recycled rubber and polyurethane in the surface layer is an environmentally friendly option that promotes sustainability. The installation process of the surface layer is complex and time-consuming, requiring specialized equipment and expertise. However, the benefits of a plastic track surface, including durability, safety, performance, and low maintenance, make it an excellent choice for sports fields and tracks.
