What kinds of ground structures are common in track and field?

In modern track and field facilities, there are various types of ground structures designed to support athletic performance while ensuring the safety and well-being of athletes. With the advancement of sports science and the development of new construction materials, many innovative surface options have emerged in recent years. However, regardless of the type of structure used, the primary concern remains the protection of athletes' physical health, minimizing injury risks, and allowing them to perform at their best without any hindrance. Common ground structures found in track and field fields include natural soil tracks, cinder tracks, polyurethane plastic surfaces, rubber sheet tracks, soft plastic tracks, sawdust-based soft surfaces, and artificial grass fields. Each of these materials has its own advantages and is suited for different types of athletic activities and environmental conditions. The diagram below illustrates the typical layers that make up a standard track and field surface:

Here is a breakdown of the layers shown in the image: 1. Synthetic soil 2. Synthetic coal residue soil 3. Polyurethane plastic 4. Rubber membrane 5. Soft plastic 6. Sawdust 7. Artificial turf 8. Asphalt concrete 9. Lime fly ash gravel 10. Lime soil 11. Breathable damping layer 12. Soil compaction Each layer plays a specific role in providing stability, shock absorption, and durability. For example, the breathable damping layer helps reduce impact on the joints, while the compacted soil base ensures proper drainage and support. The choice of materials depends on factors such as budget, climate, usage frequency, and the level of competition. Whether it's a school stadium or an international competition venue, selecting the right ground structure is crucial for both athlete performance and long-term maintenance. Understanding these components can help facility managers and coaches make informed decisions when designing or upgrading track and field areas.
