UTILIZATION OF FOSSIL-FUEL RELATED BY-PRODUCT MATERIALS FOR HIGHWAY CONSTRUCTION IN KENTUCKY. RESEARCH REPORT

The objectives of this study were: a) identify by-product materials and sources of materials that may be suitable for use in highway applications; b) conduct laboratory evaluations of mixtures utilizing by-product materials; c) develop specifications for design and construction procedures of pavement structures containing by-product materials; d) plan, design, and monitor construction of a test road(s) involving by-product materials in the pavement surface, base and/or subbase and soil subgrade; e) compare the performance and economics of sections utilizing by-product materials to conventional design and constructed sections; f) assess the positive and negative environmental impacts of using by-product materials in highway construction applications; and, g) develop specifications and recommendations for implementation of by-product materials in highway applications. This report presents the study findings. By-products examined were fly ash, bottom ash, multicone kiln dust, scrubber sludge, and two distinctly different by-products from atmospheric fluidized bed combustion (AFBC) processes. Interim reports have documented the laboratory investigations of these materials, the procedures employed to design experimental test sections using these materials, construction activities and subsequent monitoring activities, and the preliminary performance of the field trials. Conclusions from this study are that some by-product materials are very well suited for highway construction applications and that the use of the AFBC residues will require additional research before successful uses in highway applications are achieved. Further research is recommended.
