Crumb Rubber is recycled rubber from automotive and truck scrap tires. During the recycling process, steel and tire cord (fluff) is removed, leaving tire rubber with a granular consistency. Continued processing with a granulator and/or cracker mill, usually with the aid of cryogenics or mechanical means, reduces the size of the particles to the size desired. The granulate is sized by passing it through a screen, the size based on a dimension (1/4″) or mesh (holes per inch: 10, 20, 30, etc.). The more the holes in the mesh, the smaller and finer the particle. These small particles are called Crumb Rubber.
At Green Tire Disposal, we can annually produce in excess of 50 million lb crumb rubber in the USA, to be used across a wide range of innovative products, like:
· Welcome mats
· Acoustical underlay
· Anti-fatigue matting
· Railroad ties
· Weightlifting plates
· Portable speed-breaker bumps
Green Tire Disposal owns manufacturing units for crumb rubber and produces a broad array of particle sizes, with mesh 30 as it’s finest. For some applications – like those necessary to make parts for automobiles or for coatings – we supply crumb rubber in the form of “feedstock” to firms producing rubber powders that are very finely ground.
But that’s not all. Crumb rubber isn’t just molded rubber items and coatings; it enhances almost all surfaces in use in our world, be they highways or horse tracks. So what happens when rubber meets road? This is where rubberized asphalt comes into the picture.
Highways that use rubberized asphalt provide a silent riding experience, have a longer life, and utilize considerably lesser volumes of paving material vis-a-vis conventional asphalt. In this asphalt, the Crumb rubber constituent makes up 15 – 22 % of the blend, along with a customary binder. The outcome is revolutionary. Rubberized asphalt:
· Increases nighttime visibility
· Betters resistance to phenomena like cracking and rutting
· Oxidizes at very slow pace, in turn slowing aging.
· Cuts down tire noise
· Diminishes splash as well as spray when damp
Rubberized asphalt reduces maintenance costs besides providing a smoother and safer ride to motorists. Moreover, rubberized asphalt can be and is laid with the same implements as conventional asphalt, thus cutting out any extra capital outgo for contractors and municipalities.
Tire crumbs are poured in as infill between the fake grass blades which gave artificial sports fields, better known as Astroturf, more cushion and support, thereby protecting athletes. They also provide better paving, cushioning plus resilience for jogging and human sprint tracks, besides enhancing surfaces used by horses for racing or equestrian sports. This grass has become greener.
