In this report, a review of the results of this and other laboratory investigations into the material and engineering properties of bottom ashes and their performance in bituminous mixtures is presented as background information for potential users of these materials. Recommended guidelines for the selection of material sources, aggregate screening tests (gradation, specific gravity, density, etc.), mixture design and acceptance testing based upon Marshall mix design criteria, durability tests such as immersion-compression, saturation, and freeze-and-thaw, and certain performance parameters (modulus of resilience, fatigue, rutting and fracture toughness) that may be indicative of a material's future performance in service. Recommendations for suggested testing procedures and descriptions of these procedures are made, as well as suggestions for formulation of quality control guidelines for the production and stockpiling of bottom ash materials. Potential areas for future research, particularly in the areas of bottom ash behavior in the presence of moisture and development of quality tests other than Los Angeles abrasion and sodium sulfate soundness tests, which might be more appropriate to this particular type of material, are also briefly discussed. It is also recommended that freeze-and-thaw conditioning and modulus of resilience testing be considered for inclusion in aggregate screening and acceptance testing programs. /FHWA/
