This manual presents background information for people interested in the possibility of using waste sulfates in highway construction. Known sources of waste sulfate and fly ash in the eastern part of the United States are presented. Results of laboratory tests on compacted specimens composesd of fly ash, waste sulfate, lime and water are summarized. These tests include: compressive strength, tensile strength, California Bearing Ratio, permeability, freeze-thaw resistance and wet-dry stability. While the mixtures were found to have acceptable strength properties, high California Bearing Ratio and low permeability, the durability properties were judged to be marginal. This requires that care and proper precautions must be taken in using these mixtures for construction purposes. Finally, laboratory test procedures for mix design and typical specifications which might be used are suggested.
