Asphalt Rubber and Crumb-Modified Binders
We make crumb rubber for asphalt work from quality truck tires in Galion, Ohio. It’s all-black, wire-free material. Asphalt rubber and other crumb-modified binders use that rubber as part of the binder or the mix.
The sieve on the crumb has to match the mix design. We quote the size the recipe or the agency spec names.
Crumb Rubber in Asphalt Binders
In a wet-process or terminal-blend approach, crumb is mixed into the asphalt binder. In a dry process, crumb is added at the mix plant. Both show up in the field. The particle size and the gradation are written into the design, and changing the size changes how the rubber behaves in the binder.
Finer passing grades and screened fine cuts are the sizes we get asked for most on this work. That usually means 20/30 mesh, 20 minus, or 30 minus. If your design is tighter or coarser than those grades, ask about a custom size.
