This report has been prepared for the benefit of these persons involved in highway construction who are not familiar with coal ash terminology. The information presented will, it is hoped, assist them in avoiding confusion relating to the general characteristics and potential uses of the various types and classes of ash. The report covers, very briefly, some of the definitions applicable to the ash from coal burned in electric-generating plants. Major differences between "high lime" (Class C) and "low lime" (Class F) fly ash, and the need to distinguish between the two types in conducting research or experimental construction with these materials, are discussed. A broad review of potential uses of the types of ash for highway construction is given with references to papers in each area.
