ABSTRACT OF THE DISCLOSURE In the production of emulsion concrete to be laid out as a road material it is customary that the applied stone fractions are mixed together with a binder, which is a bitumen emulsion based on a relatively low viscid bitumen, as the material would otherwise be very difficult to shape by the laying operation. According to the invention the coarse stone fraction is pretreated with a rapid breaking emulsion based on high viscid bitumen, and only thereafter the fine stone fraction with low viscid binder is added. Thereby it is possible to maintain a good shapeability of the material and yet obtain a significantly improved bonding of or in the laid out material.
