PROPERTIES OF ROAD BASES STABILIZED WITH BLAST FURNACE SLAG

This study deals with the mechanical properties of road bases. The test specimens used are laboratory made samples or cores from a test road. Compression strength, creep and modulus of elasticity of the laboratory made samples were determined after different curing times. Granulated blast furnace slag was used as a binder both for road base gravel with a particle size distribution according to specifications and for air cooled slag with the same particle size distribution. Comparisons are made with road base gravel stabilized with bitumen or cement. The study shows that the curing time is considerably longer for slag stabilization than for cement stabilization. The material treated with slag also shows increasing creep and has a less pronounced cracking tendency than the identical material treated with cement. (TRRL)
