Running tracks, specifically synthetic ones, are constructed from rubber and bonded together with either latex or polyurethane, laid over a solid concrete or asphalt base.
Based on the provided reference, synthetic running tracks feature a specific composition and structure.
Key Components of Synthetic Running Tracks
To understand how running tracks are made, it's helpful to look at their primary layers and materials:
Track Materials
The visible, resilient surface of a synthetic running track is made from:
- Rubber: This forms the bulk of the track's surface material, providing cushioning, shock absorption, and traction for runners.
- Binder: The rubber particles are held together and applied using a bonding agent. The reference specifies two types commonly used for this purpose:
- Latex
- Polyurethane
These materials are mixed and applied to create the seamless, durable top layer.
Track Structure (Base)
Beneath the synthetic rubber surface, a stable foundation is essential for performance and longevity. Synthetic running tracks feature a substantial base layer underneath the surface. According to the reference, this base is typically made of:
- Concrete
- Asphalt
This underlying base provides structural support and ensures the track surface remains level and stable over time.
In summary, the construction of a synthetic running track involves laying a durable base of concrete or asphalt, followed by the application of a surface layer composed of rubber particles bonded together using either latex or polyurethane.
