Vertical deformation testing for plastic track and field facilities is conducted using a specialized vertical deformation tester, as shown in the image below. The equipment must meet specific technical requirements to ensure accurate measurements. First, the falling weight should weigh 20kg, with an allowable error of ±0.5kg. The spring must have an elongation range between 30 and 40N/cm. The test platform’s bottom diameter needs to be exactly 70mm. Additionally, the distance from the brace to the support center must be at least 200mm. The distance between the bottom of the weight and the top of the spring must be adjustable with an accuracy of less than 1mm. An electric lifting device is required, equipped with an amplifier that can measure with a precision of at least 0.01mm. Power deformation sensors are mounted on both sides of the test bench, also with amplifiers, ensuring an accuracy of 0.01mm. The recording device must be capable of storing data from both sensors, calculating results, or displaying readings—approximately 50 readings per test. The tester works by dropping a 20kg weight onto a spring, which then transfers the impact force to the lower test platform. Sensors installed on the platform record the force during the impact. The deformation of the ground is measured using sensors placed on both sides of the test bench. This setup allows for precise measurement of vertical deformation, which typically ranges between 0.6 and 1.8mm when tested at temperatures between 10°C and 40°C. This detailed process ensures that the performance and safety of plastic track and field surfaces are properly evaluated under various conditions, making it an essential part of quality control and maintenance procedures.
