- W1507789986 abstract "The construction and performance of a truck ramp made from clean coal technology waste products are described. The specific waste product used in this project was generated at the power plant located on the campus of The Ohio State University in Columbus. The ramp is used by University vehicles depositing hard trash at a central disposal facility on the OSU campus. Laboratory tests which had been conducted on samples made from the power plant waste product clearly showed that, when the material is property compacted, strengths could be obtained that were much higher than those of the natural soils the clean coal waste would replace. In addition, the permeability and swelling characteristics of the waste product should make it an attractive alternative to importing select borrow materials. Based on the results of the laboratory tests, a decision was made to use the power plant waste in the truck ramp rather than the soil that was called for in the original design. Prior to the start of construction, the area on which the ramp was to be located was covered with an impermeable geomembrane. Drain lines were installed on top of the geomembrane so that water that might leach through themore » ramp could be collected. The waste product from the power plant was placed on the geomembrane in 20 to 30 centimeter lifts by University maintenance personnel without special equipment. A drain line was installed across the toe of the ramp to intercept surface runoff, and a wearing surface of 7 to 15 centimeters of crushed limestone was placed over the compacted ash. The finished ramp structure recycled approximately 180 metric tons of the power plant byproduct. After over a year in service there is no indication of erosion or rutting in the ramp surface. Tests performed on the leachate and runoff water have shown the high pH characteristic of these materials, but concentrations of metals fall below the established limits.« less" @default.
