THE RUBBLIZATION SOLUTION

Rubblization is growing in popularity among states in need of rehabilitating their interstate highway pavements without creating the secondary problem of reflection cracking caused when underlying slabs or plates shift because of temperature changes or loads. They are reduced to smaller pieces, rubble, compacted and used to support an asphalt overlay. The article describes practices of Arkansas DOT, which is among the most active user of the technique. They use it instead of replacing pavement with concrete because asphalt takes less time and is ready sooner. Also, hauling costs and landfill costs are eliminated.
