Název v původním jazyce

Use of recycled aggregate from blast furnace slag in the design of asphalt mixtures

Popis výsledku v původním jazyce

Within a research study, blast furnace slag was used as an alternative substitute of natural crushed aggregate. Slag is in general a by-product mainly of iron and steel production and it has been used in transport engineering for many years, but only as aggregate for unbound layers or as an additive for hydraulically bound layers. Applications of steel slags in asphalt mixtures are known form several regions in the world. Any other application is currently not used. This can be also due to some problems of large road constructions (swelling) or insufficient knowledge of characteristics, source and origin of specific types of slags. This material is often being deposited in landfills, although it could be an aggregate with high quality, improved strength and anti-skid properties. In this paper there are presented data of the ongoing research, where crushed and sorted slag aggregates were used in asphalt mixtures. In the asphalt mixtures, one aggregate fraction was always fully replaced by the blast furnace slag aggregate. A number of tests was performed on the control and alternative asphalt mixtures to verify the effect of this alternative aggregate on the asphalt mixture properties. Performed tests included the determination of stiffness, determination of resistance to permanent deformation, the indirect tensile strength test, the determination of moisture susceptibility, and others.
