Asphalt and rubber

It is concluded that rubber powder become soft and bond together with each other after being mixed with asphalt. Crumb rubber modifier (CRM) or ground tire rubber (GTR) is recycled tire rubber which has been ground into very small particles to use as an asphalt modifier. Asphalt rubber mixtures have unique properties in terms of improved permanent deformation and fatigue cracking.
