TSA National Crumb Rubber Roads 

Tyre Stewardship Australia with Australian Asphalt Pavement Association, Australian Road Research Board and State Road Authorities focused on the transfer of proven crumb rubber modified (CRM) surfacing technologies to demonstrate the benefits of longer life and less maintenance in these applications.
International studies have shown that graded asphalt applications with crumb rubber modified (CRM) binders can provide improved resistance to crack reflection compared to conventional asphalt.
This resulted in the creation of national specifications for open and gap graded asphalt using crumb rubber modified bitumen in Australia.
