Detailed phenomenon and structural condition of plastic runway detection: Any phenomena such as air bubbles, cracks or delaminations are not allowed on track and field venues. Ground flatness specification: No azimuth or any direction on a track and field location within 4 meters of a linear jump interval can present a portion of convexity or concavity exceeding 6 millimeters, or within 1 meter of a straight line interval cannot present a portion of convexoconcave conditions exceeding 3 mm Each step must not exceed 1 mm.
Ground thickness specification: At the time of completion, the track and field runway has a thickness of at least 12 mm. The thickness of the runway in any azimuth must not be less than 10 mm, and the total area of the runway with a thickness between 10-10.5 mm must not exceed 5% of the total area of the track and field. The heavy weight areas (pole vault, javelin, triple jump approach area and high jump area) that should be particularly thickened are not taken into account when calculating the above average.
Straight deformation inspection: Straight deformation inspection uses a straight deformation tester. The inspection is performed on the runway and runway (including the thickened area), and the temperature during the inspection is 10 ℃ -40 ℃. The straight deformation on artificial track and field should be between 0.6-1.88 mm.
Color: For the evaluation of the color on the artificial track and field, the color of the plastic should be consistent with one of the colors in the manual. Regarding the carefully designed multi-color plastic runway, each color should be generally consistent with the relevant colors in this manual. Advantages of using silicon PU field data on campus Nowadays, the courts of the campus basically use silicon PU data. The silicon PU field data has very good advantages and results.
