Abstract
An apparatus for applying an asphalt binder composition to a roadway during construction or repair of an asphalt pavement which apparatus include: a mobile vehicle having a chassis extending in a longitudinal direction which longitudinal direction is aligned with a forward/rearward direction of travel of said mobile vehicle; at least one storage tank supported on the chassis containing an asphalt binder composition; and at least one spray nozzle configured to dispense the asphalt binder composition from the at least one storage tank in a longitudinal strip or band having a width that is no greater that a width of the asphalt binder composition dispensed by one of the at least one spray nozzle. The at least one spray nozzle can include a plurality of spray nozzles that are coupled to a common spray bar. According to one embodiment the asphalt binder composition is a void reducing asphalt membrane composition that is provided between adjacent asphalt pavement passes.
