Abstract: Process and device for fabricating bituminous coated products from aggregates enclosing a large quantity of fines, using a drying-mixing drum having a case (1) provided internally with fins of which some effect a complete raising of the aggregates in a drying zone (7, 8). Liquid bitumen is incorporated in the aggregates at the end of the drying zone (7, 8) with a raising of the aggregates. The hot mixing of the aggregates and the bitumen is effected in a zone (9) where the aggregates remain in contact with the wall of the drum. The excess fines in the hot gases at the outlet (3) of the drum are recovered. The process is also applicable in the use of recycled materials for producing the coated products.
