Utilization Of Fossil-Fuel Related By-Product Materials For Highway Construction In Kentucky, David Q. Hunsucker
Utilization Of Fossil-Fuel Related By-Product Materials For Highway Construction In Kentucky, David Q. Hunsucker
Kentucky Transportation Center Research Report
In an effort to increase the utilization of fossil-fuel by product materials in highway construction project, the Kentucky Transportation Cabinet authorized the experimental use of several waste materials. These materials included bottom ashes, fly ash, scrubber sludge, multicone kiln dust, and residues tram atmospheric fluidized bed combustion processes. Bottom ash aggregate was used as a partial replacement for the limestone aggregate in a bituminous surface mix. Non-specification fly ash was used in lieu of Class F fly ash in a stabilized aggregate base. Bottom ash stabilized with residue from an atmospheric fluidized bed combustion process was used as a highway …
Performance Of Experimental Highway Base And Subbase Layers Containing Coal-Fired Power Plant By-Product Materials: Ky Route 3074, Bleich Road, David Q. Hunsucker, R. Clark Graves
Performance Of Experimental Highway Base And Subbase Layers Containing Coal-Fired Power Plant By-Product Materials: Ky Route 3074, Bleich Road, David Q. Hunsucker, R. Clark Graves
Kentucky Transportation Center Research Report
Three 750-foot test sections of a 22-foot wide roadway were constructed on newly constructed subgrade in May and June, 1988. The three experimental sections contained experimental base and subbase layers comprised of mixtures utilizing by-product materials from a coal-fired power plant One test section included a base layer containing residue from an atmospheric fluidized bed combustion (AFBC) process, size No. 57 aggregate, and Class F fly ash. The second test section included a base layer constructed ponded fly ash, hydrated lime, and dense-graded aggregate. The third test section included a subbase layer constructed of pond ash stabilized with AFBC residue. …
