Sandwich System Spray Coating Running Track For University Competition Stadium

The sandwich system running track is a type of athletic track construction that consists of multiple layers or "sandwiches" of different materials. This construction method is designed to provide enhanced performance, shock absorption, and durability for athletes.

The sandwich system running track consists of the following layers:

1. Base Layer: The base layer is the foundation of the track system and is usually made of compacted aggregates or asphalt. It provides stability and structural support for the track.

2. Shock Absorption Layer: This layer, also known as the cushion layer, is designed to absorb impact forces and reduce the strain on athletes' joints and muscles. It is typically made of materials like SBR (Styrene Butadiene Rubber) or recycled rubber granules.

3. Top Layer: The top layer is the visible and running surface of the track. It is responsible for providing traction, grip, and a smooth running experience. The top layer is commonly made of materials such as polyurethane (PU) or latex, which offer excellent elasticity, energy return, and durability.
