Properties of concrete pedestrian block mixed with crumb rubber

Recycling granulated waste tires (crumb rubber) has been widely studied for the last twenty years mostly relating to applications such as asphalt pavement, waterproofing system, membrane liners, etc. In this study, the use of crumb rubber to replace coarse and fine aggregates in concrete pedestrian block was studied. It is believed that concrete acting as a binder mixed with crumb rubber can make concrete blocks more flexible and thus, provide softness to the surface. The crumb rubber block also performed quite well in both skid and abrasion resistance tests. The production process was economical, due to the simplicity of the manufacturing process.
