Development and demonstration of large-volume beneficial use applications for ponded fly ash are considered very important as a cost reduction strategy for the generation industry and value enhancement for the coal mining industry. One such application described is the road sub-base fo the Industry Access Truck Route in Meredosia, Illinois, which used approximately 77,000 cubic yard of compacted high loss-on-ignition (LOI) Class-F ponded fly ash. The Truck Route is a 24-feet wide road built on a 0 to 7 feet thick compacted fly ash sub-base. Illinois Department of Transportation estimated that the use of fly ash in this project saved more than $100,000 to the State of Illinois. Furthermore, natural resources in the form of relatively fertile soil were preserved by substituting fly ash for the available borrow in the area; quality agricultural topsoil is limited in the area. The article gives details of the project and reports favourable results on monitoring ground water quality. 2 refs., 1 fig.
