Gravelling vehicle for roads has discharge ramp with multiple nozzles for pre coating and final coating of gravel on road surface

摘要

The gravelling vehicle has a discharge ramp (7) with multiple nozzles for dispersing binder (9) falling directly on the road surface. A second series of binder nozzles pre-coat the gravel as it is still in the chute between the opening of the hopper and the ground. The secondary nozzles can be fixed to a separate ramp (16) operating in the output area.
