Abstract: Bitumen granules which contain 0.5 to 15% by weight, preferably 6.1 to 15% by weight, of a re-powdering and separating agent such as, for example, synthetic silica or carbon black, are produced by atomising hot liquid bitumen in a known spray mixer and simultaneously introducing the repowdering and separating agent into the spray mixer via the cold air stream.
