Process for preparing a mixture of bitumen, a high-boiling hydrocarbon and a rubber-like copolymer of ethylene, at least one other alpha-alkene and, if necessary, one or more polyenes

摘要

A mixture containing bitumen, a high-boiling hydrocarbon and an EPDM-rubber is prepared by dissolving the EPDM under special conditions in the hydrocarbon and by subsequently mixing the resulting solution with bitumen. An improved bitumen is obtained that can be applied, for instance, in road construction.
