摘要

The data on the static friction coefficient (μ) resulting between a surface and a friction block covered with shredded rubber produced from used commercial tires at varying granule sizes are presented. The tests are done using different types of plates such as, glass, Poly Vinyl Chloride (PVC) plastics, wood, concrete, marble, ceramic and sand paper to represent rough and smooth surfaces in contact with shredded rubber granule of sizes 1.18?mm, 0.6?mm, 0.425?mm, 0.3?mm, and 0.15?mm. The coefficient of static friction is calculated using Coulomb?s Law of dry friction and the data are compared based on the granule sizes variability.The data are represented in tables and figures. The data are in an almost uniform trend among the surfaces starting with a lower coefficient of friction for 1.18?mm to 0.6?mm, reached the highest at 0.425?mm and drops eventually as soon as the granules are finer.
