Abstract
In this paper the use of foam bitumen to achieve a bituminous bound foundation layer with the characteristics of a bituminous concrete asphalt layer is described. The stabilization is performed by using a mobile road recycler equipped with a spray bar system. Zinc slag material can be safely used as a road material using this technique. The technique and the subsequent environmental testing programme are described. The German title of this article is: Stabilisierung der Hochofenschlake Mittels Schaumbitumens.
