The width of the standard plastic runway is1.22m. If the venue is narrow, 1.0- 1.2m can also be used. Plastic track has always been a good choice for schools because of its high friction and elegant appearance, and 400m plastic track is the best choice for schools.

The runway width is 1.22m, the number of curved runways is 8, and the number of straight runways is 10. The safety zone inside and outside the runway shall not be less than 1m, the starting safety zone shall be greater than 3m, and the safety zone in the sprint buffer zone shall not be less than 17m. The runway inclination shall not be greater than 1: 1000. The total length of the standard runway is 400 meters. The inside of the runway shall be made of suitable materials as the protruding boundary, and the protruding height and width shall be at least 5 cm.

Plastic track, also known as track and field track, consists of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM particles or polyurethane particles, pigments, additives and fillers. Plastic track has the characteristics of good flatness, high compressive strength, suitable hardness and elasticity, and stable physical properties, which is beneficial to the development of athletes' speed and skills, effectively improving sports performance and reducing the fall rate.

Maintain knowledge

It takes 7- 10 days to use the plastic track after it is laid.

The plastic runway is suitable for all-weather use with certain drainage facilities. Plastic track is used for athletes' training, competition, students' sports and fitness exercise, but not for other purposes.

The rubber runway should avoid the pollution of harmful substances and severe mechanical impact and friction, and vehicles are not allowed to drive on the runway and pile up heavy objects and sharp objects. Athletes must wear special sports shoes or sneakers. Dancing shoes should not exceed 12 mm, and if sports shoes have spikes, the spike length of sports shoes should not exceed 9 mm.

Pay special attention to protect the edge of the plastic runway and don't tilt at will. If the kerb is found to be damaged or blistered, the construction unit shall be informed to repair it in time to avoid more serious damage.
