THE UTILIZATION OF INCINERATED ANTHRACITE MINE REFUSE AS AN AGGREGATE IN BITUMINOUS MIXES FOR SURFACING HIGHWAYS

Special Research Report SR-96 There have been approximately 910 million tons of anthracite refuse accumulated in the anthracite region of Northeastern Pennsylvania since the mining of this coal started in the middle 1800's. This refuse is most objectionable, since it occupies valuable space) it represents a potential source of air and water pollution, and in general, it has retarded the economic growth and industrial development of the region. A research program, "Operation Anthracite Refuse," was initiated in 1968 by the former Department of Mines and Mineral Industries (now the Department of Environmental Resources) of the Commonwealth of Pennsylvania and financially supported (90 percent) by the United States Bureau of Mines, to determine possible uses for the refuse in order to help rid the area of this material.
