Abstract (en)
[origin: US4492728A] The covering has a lower or cushioning layer (1) and an upper or wear-resisting coating (2), between which there is a reinforcing iron netting (3). Both the layers contain rubber chips (4), which are produced from old vehicle tires. The lower layer used for cushioning impact effects on the covering, is additionally provided with spherical expanded clay (5), which gives said layer a particular elasticity and also makes it independent of atmospheric humidity during production.
