Abstract:

Waste foundry sand has been rediscovered as a road construction material now that environmental concerns about its use have been laid to rest. Certain types of waste foundry sand, a by-product of the foundry casting process, have been shown to be environmentally acceptable. In Indiana, Auburn Foundry supplied the state Department of Transportation with waste foundry and for use in the construction of an embankment. The waste foundry sand, tested and approved as environmentally sound, proved comparable to traditional construction materials in terms of compaction and performance.
