Some 20 or so years ago there was a guy in Fontana,Ca. buying up huge piles of used tires to be used in some new pavement formula but that fell through for some reason. I don't know what happened to all those tires or the scheme to use them in pavement.

Rubber road took a wrong turn; Shredded tires that caught fire in Garfield County are hauled back to where they came from | Northwest | lmtribune.com
SPOKANE -- It sounded like the perfect solution.
State and county officials reasoned that shredding 1.4 million used tires for use in road construction would alleviate a potential fire hazard in the storage yards where they were being kept.
The tire-chip material went into a road bed near Pomeroy in Garfield County late last year.
But within weeks, it began to smolder, emitting smoke and even flames at the road surface. Removal cost millions and the shredded tires are now buried in a landfill a few miles from where they were stored before the failed experiment.
Federal highway officials have ordered a national moratorium on shredded-tire highway projects until someone can explain what went awry in Washington.
