Abstract (en)
[origin: WO2018046837A1] A method for manufacturing a material in divided form that is solid at ambient temperature and usable as a road binder or as a sealing binder, such as a road bitumen, a pitch, a stock solution for a bitumen/polymer composition, a clear binder, said method comprising the implementation of a device (1) intended for granulation that comprises at least two coaxial drums (4A, 4B) and a horizontal running belt (6): a fixed inner drum (4B) comprising at least one orifice (5B) and a rotating outer drum (4A) comprising a plurality of orifices (5A), said method comprising at least: (i) heating a first composition (2) to a temperature at which it is fluid, (ii) introducing the first composition (2) in the fluid state into the inner drum (4B) of the granulation device, (iii) distributing the first composition outwards in the form of drops (7) through the orifices (5A) in the rotating outer drum (4A), (iv) depositing the drops (7) on the running belt (6), and (v) optionally, coating the drops (7) with the second composition. A device for manufacturing these materials.
