STEEL SLAG ASPHALT MIXES
Steel slag asphalt mixes are widely used in the United States and Britain, but to date there has been little use of such mixes in Canada. The introductory portion of this paper outlines the very important differences between blast furnace slags and steel slags, and indicates the general acceptance and experience with steel slag asphalt mixes in the United States and Britain. Details are also presented on the use of precoated steel slag chippings in Britain. The various steel slag asphalt mixes placed in the Hamilton-Toronto area are discussed with particular emphasis on wear resistance, skid resistance and compaction behavior. Steel slag asphalt mixes have extremely high stabilities and flows, and the influence of these high stabilities on compaction has been examined through a field test program. It has been found that adequate compaction is achieved. The use of steel slag in asphalt patching mixes is reviewed with emphasis on applications in Hamilton. Laboratory studies concerning the gradation, composition and Marshall design of steel slag asphalt mixes are presented. The final portion of the paper outlines studies that are in progress on the design of fine steel slat slurry seals, and the rational design of steel slag flexible pavements.
