Introduction Plastic running tracks have become increasingly popular in recent years due to their durability, low maintenance costs, and environmental friendliness. However, to ensure their safety and performance, regular maintenance and testing are necessary. In this article, we will introduce the top ten recommended testing methods for plastic running tracks, as suggested by Kojie, a leading manufacturer of athletic track materials. 1. Surface Hardness Test The surface hardness test is used to determine the hardness of the plastic running track surface. This test is important because a surface that is too hard can cause discomfort and injury to athletes, while a surface that is too soft can lead to premature wear and tear. The test is conducted using a durometer, which measures the resistance of the surface to indentation. 2. Vertical Deformation Test The vertical deformation test is used to determine the level of deformation of the plastic running track surface under pressure. This test is important because excessive deformation can cause discomfort and injury to athletes, as well as affect their performance. The test is conducted using a special device that applies a specific amount of pressure to the surface and measures the resulting deformation. 3. Force Reduction Test The force reduction test is used to determine the level of shock absorption of the plastic running track surface. This test is important because a surface that does not absorb enough shock can cause discomfort and injury to athletes, while a surface that absorbs too much shock can affect their performance. The test is conducted using a special device that measures the amount of force absorbed by the surface when a weight is dropped on it. 4. Water Permeability Test The water permeability test is used to determine the level of water permeability of the plastic running track surface. This test is important because a surface that is not permeable enough can lead to water accumulation and damage, while a surface that is too permeable can lead to excessive water drainage and affect the stability of the track. The test is conducted by pouring a specific amount of water on the surface and measuring the time it takes to drain. 5. Color Fastness Test The color fastness test is used to determine the level of color fastness of the plastic running track surface. This test is important because a surface that fades or changes color over time can affect the aesthetics of the track and its visibility to athletes. The test is conducted by exposing the surface to various environmental conditions, such as sunlight and water, and measuring the level of color change. 6. Skid Resistance Test The skid resistance test is used to determine the level of skid resistance of the plastic running track surface. This test is important because a surface that is too slippery can cause athletes to lose their footing and fall, while a surface that is too rough can cause discomfort and injury to athletes. The test is conducted by measuring the level of friction between the surface and a special device that simulates the movement of an athlete's foot. 7. UV Resistance Test The UV resistance test is used to determine the level of UV resistance of the plastic running track surface. This test is important because exposure to UV radiation can cause the surface to degrade and lose its properties over time. The test is conducted by exposing the surface to UV radiation for a specific period of time and measuring the level of degradation. 8. Chemical Resistance Test The chemical resistance test is used to determine the level of chemical resistance of the plastic running track surface. This test is important because exposure to certain chemicals can cause the surface to degrade and lose its properties over time. The test is conducted by exposing the surface to various chemicals and measuring the level of degradation. 9. Abrasion Resistance Test The abrasion resistance test is used to determine the level of abrasion resistance of the plastic running track surface. This test is important because excessive abrasion can cause the surface to wear out prematurely and affect its performance. The test is conducted by subjecting the surface to a specific amount of abrasion and measuring the level of wear. 10. Dimensional Stability Test The dimensional stability test is used to determine the level of dimensional stability of the plastic running track surface. This test is important because a surface that is not dimensionally stable can warp or deform over time, affecting its performance and safety. The test is conducted by exposing the surface to various environmental conditions, such as temperature and humidity, and measuring the level of dimensional change. Conclusion In conclusion, regular testing and maintenance of plastic running tracks are essential to ensure their safety and performance. The ten testing methods recommended by Kojie provide a comprehensive and reliable way to assess the quality of plastic running tracks. By following these recommendations, track owners and operators can ensure that their tracks are safe, durable, and environmentally friendly, providing athletes with the best possible experience.
