Memory may be hazy, but ISTR that several years ago a couple test
stretches of hiway were paved with a mix that included old ground-up
tires in the asphalt and/or concrete. The reason this practice wasn't
used widely was that the surface lasted much longer which meant less
labor was needed over the long term. Texas had one of the test hiways
IIRC.

California did a section of freeway in Oakland that way last fall. It's
shot, now. One of the worst in the area, after 4 to 6 months. Much worse
than before they started. I don't remember what went wrong, but something
certainly did.
