MALES, National Lime AssociationJAN R. PRUSINSKI, Portland Cement AssociationBARRY STEWART, American Coal Ash AssociationThe principal materials used for the Cementitious Stabilization and modification of highwaypavement materials are lime, fly ash, and portland cement. Whereas lime and portlandcement are manufactured products, fly ash is a by-product of the burning of coal at electricpower generating stations. As a consequence, fly ash generally exhibits greater variabilitythan is seen in the other products. By-products such as kiln dust and fluidized bed ash fromvarious manufacturing and energy generating processes are used to a lesser extent. Whileall of these products and by-products are used for similar purposes, different testing,design, construction, and quality assurance/quality control (QA/QC) methodologies havebeen developed for projects are almost always site-specific, requiring the application ofstandard test methods, along with fundamental analysis and design procedures, to developan acceptable solution.
