Abstract
Two dopants are successively added to the mixtures of aggregates and hydrocarbon binder forming each covering layer. One is based on anthracene oil, tar, natural resins, bitumen and chalk. The other is based on amines. This results in perfect coating even if the aggregates are wet and avoids flocculation which is often produced in the bitumen-tar mixtures.
