Design And Performance Of A Bituminous Surface Mixture Containing Bottom Ash Aggregate, David Q. Hunsucker
Kentucky Transportation Center Research Report
A one-mile experimental bituminous surface overlay was placed in October 1987 on State Route 3 in Lawrence County, Kentucky. The experimental section utilized bottom ash aggregate from the Kentucky Power Company's Big Sandy Power Plant, near Louisa, Kentucky. Bottom ashes are generally angular and have very porous surfaces. Approximately 539 tons of the experimental bituminous surface material, containing 40 percent bottom ash (dry weight), were placed. Reported herein are results of laboratory tests and performance evaluations of the experimental surface mixture.
Performance of the experimental bottom ash surface has been excellent. Skid resistance tests indicate the surface is highly skid …
