The machine is composed of a vehicle e.g. lorry, on which is mounted a complete bitumen spreading system (1) whose pressure nozzles (2) are extensible. The vehicle has removable and extensible rollers (5), and a gravels depositing system (4) with three diffusers, of which two are mounted on guide rails. The binders and gravels are spread at the same time, at the same place, and rolled immediately afterwards.
