Semi-prefabricated runway coils are divided into upper and lower layers. The upper layer is a flat and dense structure with a depth of 3~5mm TPV or EPDM colored particles, which provides the friction and elasticity required by the runway; the lower layer is a grid with a depth of 8-10mm with an inclination angle. The frame structure provides the shock absorption and main elasticity required by the runway. The feature of this structure is that it can relatively condense the scattered reflection force, and act on the athlete at an angle in line with the forward direction of the athlete to improve the sports performance.
