Apparatus and method for applying asphalt binder compositions including void reducing asphalt membrane compositions for paving applications
First Claim
1. A method of applying an asphalt binder composition along a longitudinal joint area of roadway during construction or repair of an asphalt pavement which comprises:
- providing;
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
an asphalt binder spraying system that consists of a plurality of spray nozzles that are all located outward beyond an outer side of the chassis and configured to dispense the asphalt binder composition from the at least one storage tank to form a discrete narrow strip or band that is no wider than a combined spray pattern of the plurality of spray nozzles of the asphalt binder spraying system and which narrow strip or band extends in the longitudinal direction,moving the mobile vehicle along a roadway to be repaired or paved with asphalt; and
dispensing the asphalt binder through the plurality of spray nozzles in said longitudinal strip or band along the longitudinal joint area.

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.
