Generally speaking, the runway refers to track and field runways in schools and professional stadiums at all levels. There are standard runways and non standard points. The standard runway refers to the 400 meters perimeter and a radius of 36.5 meters. In addition, there are two kinds of non - standard runways of 36 and 37.898 meters, which refers to the proper adjustment of the radius and the circumference of the playground according to the shape and size of the ground area used in the playground, and the common perimeter is 200 meters and 300 meters.
The prefabricated rubber rolling track and mixed type plastic runway, because of its unparalleled excellent performance is the common type of professional track and field sports field, but its price is high. The performance of the compound type plastic runway is between the mixed type and the air permeable type, the price is slightly lower than the mixed type of the plastic runway, but it is also a lot higher than the air permeability. Ask for higher. The performance of the air permeable plastic runway can reach all the GB/14833-93 indexes, and the short maintenance refurbishment is easy to be renovated in the air permeable and permeable construction period. The highest price performance is also the first choice in the primary and middle schools. The EPDM plastic runway is mainly used for non standard runways, such as primary school or kindergarten.
1, mixed type plastic runway
The hybrid structure surface approved by IAAF is PU particle or EPDM weatherable and environmental friendly color particle. The parent body is full PU mixed with some rubber particles. The construction technology is in line with the international standards. The standard thickness is 13mm.
2. Compound plastic runway
The upper layer of the composite structure approved by the IAAF is PU particles or EPDM weatherproof and environmentally friendly polyurethane sealing with color permeable particles, and the lower layer adopts mechanical construction cushion. Meet the standards of international competition. The standard thickness is 13mm.
3. Air permeable plastic runway
The upper structure of the composite structure recognized by IAAF is PU particles or EPDM weatherability, environmental protection and color particles mixed mechanical spraying, and the lower layer is cushion cushion for mechanical paving. Meet the training standards of professional track and field athletes. The standard thickness is 13mm.
