MASUGNSSLAGG SOM VAEGMATERIAL I SVERIGE (BLAST-FURNANCE SLAG AS A ROAD-BUILDING MATERIAL IN SWEDEN)

An increasing shortage of gravel in Sweden and certain interesting characteristics of blast-furnace slag have made its use as a stabilizing material in road-building possible. Asphalt and cement are considerably more expensive than slag, so it can now be used even at a rather long distance from the iron works. With the aid of the calculations which have been carried out on Merolit and slag binding agents, together with natural materials, as a substitute for bitumen-stabilized gravel in roadbeds, it should be pointed out that large portions of Sweden are accessible for the use of blast-furnace slag as far as the practicality of transporting it is concerned. However, great uncertainty prevails with regard to blast-furnace slag's technical characteristics--its carrying capacity and tendency to crack, for example--and that naturally is of great importance where questions of how various slag materials can and should be used in road-building are concerned. Blast-furnace slag's frost-insulation capability is also of interest here, and it should not be left out of the discussion. Certainly it is so interesting that further investigation of that material's characteristics is justified.
