Abstract
Apparatus for spreading a bonding emulsion for road asphalt, a bituminous fluid substance or a similar fluid substance onto the surface of a road, comprising on a moving machine spreading booms associated with ejection nozzles as well as feed circuits for the nozzles, the booms being capable of moving transversely relative to the direction of movement of the moving machine, and being associated with motor mechanisms to drive them during spreading in a to-and-fro movement. The nozzles thereby perform continuous complementary dynamic spreading on the road surface, with the to-and-fro distance of travel of some of the booms being adjustable as a function of the road width over which spreading is required.
