Airport Apron Project Using Glass Aggregate Finishes Early
Abstract
The airport, located on the Delaware River, used the recycled aggregate supplied by Aero Aggregates of North America to finish the 58,000-sq-ft overnight parking apron. Contractor James J. Anderson completed the project, which had a November deadline, in three months instead of nine using ultra-lightweight foamed glass aggregate. Filshill says the aggregate is light, so unlike heavy fill dumped after excavating or pile driving, only a small amount of soil is removed before the aggregate is placed. One truckload of aggregate is equivalent to 6 or 7 dump trucks of fill. Placing the aggregate required no specialty subcontractor or contractor. "We were looking as cutting as much as 12 months but expected 6 to 9 months by going with the lightweight aggregate," Allen says. Each Aero Aggregates location diverts the equivalent of over 140 million glass bottles per year from landfills and reduces the number of trucks on the road due to the increased volume per delivery.
