Crumb Rubber Use in Asphalt New Technology Developments

Technical Note TN193 Use of recycled materials in road

2.1 Crumb rubber Crumb rubber is derived from end-of-life tyres. Rubber and carbon black represent approximately 70% of the weight of a tyre. To make crumb rubber, end-of-life tyres are shredded, then further processed into a crumb. A high-value application for these materials is as crumb rubber modified (CRM) bitumen for use in road construction.

Crumb Rubber as a Secondary Raw Material from Waste

This approach produces crumb rubber, which can be used as a material to entirely or partially replace mineral aggregates, producing more environmentally friendly composite materials, such as rubberized asphalt pavement [8,9]. Binder modification with crumb rubber is a modern technology for asphalt production with lower ductility [10].
