Abstract
The present work aims to test the frictional behaviour of rubber mats made of recycled rubber and filled by polyurethane of different hardness to have specific information about their friction coefficient and evaluate their performance in increasing friction coefficient at dry, water, detergent wetted flooring. The presence of dust contaminating the floorings was tested. It was found that at dry sliding, friction coefficient slightly decreased with increasing the hardness of the rubber mats. At water wetted and sand contaminated rubber mats, the variation of friction coefficient with increasing the hardness of the tested rubber mats was significant. Compared to ceramic and polymeric tiles, rubber mats showed the highest friction.
