| (54) | Drying-mixing drum for preparing bituminous mix, particularly by use of recovered material |
| (57) The drum is provided with a burner (7), which is made operating with controlled amount
of air so as to avoid that its flame causes the combustion of the bitumen contained
in the recovered material. Bituminous mixes of very good quality with high percent
of recovered material can thus be obtained. |
