ABSTRACT:
A water supply system is adapted to spray lubricant, typically water, onto an asphalt surface in front of an asphalt vibratory plate machine at a generally constant rate regardless of the level of lubricant in the system's storage tank and regardless of machine inclination. The water is routed to a nozzle assembly of the water supply system through a pump that is preferably driven by the exciter of the asphalt vibratory plate machine. The pump is configured to provide adequate pressure with minimal increase in the machine's overall weight, complexity, or manufacturing expense. The nozzle assembly includes a spray bar which is configured to spray water uniformly across the entire compaction path but which is shorter than the baseplate of the machine so as to avoid snagging on neighboring obstructions.
