Study on Coal Ash Use in Transportation
Fly ash is a byproduct of coal combustion for electricity generation. It is widely used as a supplementary cementitious material in the production of concrete. Fly ash concrete is a mixture of choice for many state and local transportation departments and transportation engineers because of its performance enhancing and cost-saving benefits. It has also been praised for its environmental benefits as a "green" building material-putting to use an energy production byproduct that reduces demand for carbon-intensive portland cement, requires less water in the setting process, and would otherwise wind up in a landfill. Despite its many documented advantages and widespread use, new proposed disposal regulations may limit or eliminate its availability. The ARTBA-TDF study was conducted to forecast the potential economic impacts of the loss of fly ash availability in just one U.S. construction market-transportation infrastructure.
