cement concrete pavement recycling

100 Years of Concrete Pavement In Iowa

Recycling concrete pavement into granular subbase was a time consuming process. First, the pavement was broken with a pavement breaker. Next, the rubblized pavement was hauled to a plant site, crushed and then hauled back to the project site. In 1993, Manatt's Inc., Duit Construction and Wendling Quarries developed a concept to break,
