Waste and Secondary Product Utilization in Highway Construction

Abstract

<p>A satisfactory base stabilization process utilizing ground pelletized blast furnace slag as the cementing material has been developed. A number of aspects of pelletized slag base stabilization such as energy utilization, type of ground fines, catalysis effects, glass content, fly ash utilization, etc. are considered. The setting problems associated with the high lime content of steel slags in emulsified asphalt slurry seals were overcome by using blends of quick and slow set anionic emulsions. A large amount of information on waste and secondary product utilization is integrated throughout. Recommendations for future studies are given.</p>
