STRENGTHS AND RESILIENT MODULUS FOR CRUSHER RUN BLAST FURNACE SLAG AND ADDITIVES

This paper summarises investigations carried out on the suitability of air cooled blast furnace slag, blast furnace granulated slag and basic oxygen steelmaking slag as road base materials. Since road making materials are increasingly being characterised by use of resilient moduli, the compressive strengths and resilient moduli were determined for road base of the following slags: 1) air cooled crushed blast furnace slag, 2) mixes of air cooled blast furnace slag, granulated slag, and lime 3) mixes of air cooled blast furnace slags, granulated slag and basic oxygen steelmaking slag. Evaluation of local dacite (dense medium grained igneous rock, classification rhyolite), generally considered an excellent road base course material, was carried out for use as a reference material. Tests carried out consisted of unconfined compression and repeated axial load triaxial compression. For all three slags investigated resilient moduli values varied with changes in deviator stress and sample age. Final results indicate that air cooled blast furnace slag would perform well as an unbound granular road base material. The remaining slag mixes tested exhibited the characteristics of excellent stabilised base materials. /TRRL/
