The IAAF places significant emphasis on the development and maintenance of grassroots track and field facilities. According to official guidelines, the lifespan of such venues should be at least two to three times that of the synthetic surface materials used. This means that the foundation of a track should be designed to last between 25 to 30 years, ensuring long-term usability and cost-effectiveness.
The organization has outlined specific criteria for designing running tracks:
1. The foundation must be strong enough to support heavy construction equipment and materials without deforming or exceeding the ground’s load capacity.
2. It should provide adequate structural support, ensuring that the playing surface remains stable under the weight of athletes and training activities.
3. The design should protect the ground from damage caused by groundwater and frost, especially in colder climates.
4. The surface should offer optimal interaction between the athlete and the ground, enhancing performance and safety.
5. Proper drainage is essential to manage rainwater and groundwater, directing it away from the track and into the soil or drainage systems.
6. After heavy rainfall, there should be no standing water on the track, as this can disrupt training and competitions.
7. All these standards must be followed throughout the entire construction process to ensure quality and durability.
8. Cost efficiency is also a key consideration, balancing initial construction expenses with long-term maintenance costs.
The IAAF emphasizes that even in ideal conditions, a minimum of 150mm of free-draining material should be placed beneath 60mm of asphalt concrete. In less favorable environments, a thicker structural layer—ranging from 400 to 500mm—is recommended. This is particularly important in regions where winter temperatures frequently drop below freezing, as a deeper structure helps prevent frost heave, which can damage the track and compromise its integrity over time.
Gas Pizza Oven:
Make your oven more versatile by using it not just for traditional baking, but also for creating restaurant-quality pizza. Expertly engineered features work together to ensure the right amount of heat in all the necessary areas.
Precision Surface Sensor:
This sensor, positioned directly beneath the cooking surface, monitors the oven temperature and alerts you when it's time to start cooking your first pizza or add another.
Broil Amplifier:
Situated between the heater and the top of the oven, the reflective aluminum shield redirects heat downwards to achieve the perfect browning of your pizza crust and toppings.
Built-In Rapid Crisping Plate:
The cooking surface features a quarter-inch thick plate made from durable aluminum alloy. This plate provides rapid heat conduction and precise temperature control, allowing you to cook various styles and sizes of pizza to your desired level of doneness.
