RIGID CONCRETE RECYCLING COMES OF AGE

Recycling Portland cement concrete has evolved from an experimental technique to an accepted construction procedure. And as recycling gains momentum, existing pavement in need of reconstruction is being regarded as a readily available source of aggregate rather than a troublesome waste product. Among the reasons cited for the increased interest in recycling are a shortage of high-quality virgin aggregate in some areas, the problem of disposing of the old concrete and the opportunity for savings in material and transportation costs. In order to highlight the principles involved in concrete recycling technology, this article discusses how the Iowa Department of Transportation decides whether to recycle or to use virgin aggregate.
