Abstract
A method for producing a solid intermediate compound for incorporating into liquid bitumen obtained from petroleum or into mineral oils in order to produce liquid/polymer bitumen. According to the method, a polymer for producing the liquid/polymer bitumen is hot-mixed with solid bitumen, the mixture is then cooled, and the solid intermediate compound thus obtained is split. The intermediate compound obtained, the liquid/polymer bitumen formed from the intermediate compound, and a bitumen-coated material containing the intermediate compound or liquid/polymer bitumen are also disclosed.
