Asphalt Fact #03: One of the most cost-effective ways to rehabilitate a worn-out concrete highway is to rubblize it, then overlay it with asphalt.
In Arkansas, 276 miles of concrete interstates were given new life in a rubblize-and-overlay program. Rubblization makes the base into an interlocked matrix of pieces as the concrete breaks up. The asphalt overlay can even turn a failed concrete pavement into a Perpetual Pavement.
Resonant Machines will be at the SCAPA Winter Conference on February 23rd spotlighting this road rehab strategy.
