Research and applied utilization activities for the increased use of ferrous and nonferrous slags in civil and highway construction are presented. The overall use of blast furnace slag is relatively well known for a range of highway construction applications from granular base to supplementary cementitious materials. In contrast to blast furnace slag, which is volumetrically stable and straightforward in its construction uses, steel slag contains hydratable oxides that can result in volumetric instability that must be dealt with through appropriate steel slag aging, testing and quality control to ensure its appropriate use in highway construction. There is a full range of proven civil and highway construction uses - from aggregate to cementitious materials - for copper, nickel and phosphorus nonferrous slag. The scope of a new technical text on the technology of slag utilization is reflected throughout to provide a practical context for the highway engineer.
