This guide, which is supplementary to the Association’s Guide to the Use of Slag in Roads, reviews in detail the use of steel furnace slag in asphalt and thin bituminous surfacings. The Guide shows that, with technical evaluation supported by field experience that steel furnace slag has in many applications properties suitable to replace, supplement, and improve other materials. The use of steel furnace slags in these ways also has environmental benefits in allowing the conservation of depleting natural resources.

The purpose of this Guide is to provide information to designers, specifiers, and providers of bituminous road surfacings on the properties of steel furnace slag aggregates so that they may be considered on an informed basis when comparisons are being made with other aggregates. The Guide forms part of a continuous improvement process that aims to optimize the opportunities for the use of steel furnace slag aggregates.

As there are many types of slag, it should be emphasized that this booklet refers particularly to basic oxygen steelmaking slag and/or electric arc furnace slag, which are steel furnace slags. Hard copies are available to members at a cost of $10.00 each, non-members $15.00, plus postage and handling. An electronic version can be downloaded via our Library.
