THE USE OF LUMP SLAG AND CRUSHED BLASTFURNACE SLAG IN PAVEMENT LAYERS

KAPPALEKUONAN JA MASUUNIKUONAMURSKEEN KAYTTO PAALLYSRAKENNEKERROKSISSA

Experiences have shown that air-cooled blastfurnace slag lends itself for use in unbound structural pavement layers. The porosity of its grains is attributable to the way in which they are created. They are characterised by a rough surface and a cubic, angular form so that their internal friction coefficient is large and load bearing value higher than that of natural aggregates of the same grain-size distribution. Bearing dimensioning is performed in the usual manner in accordance with the pavement planning instructions employed in the Finnish National Road Administration or in the form of a durability analysis based on critical loading strains.
