ABSTRACT:
An asphalt distributor has a spray bar assembly that includes at least one extendable and retractable spray bar section for extending the overall width of the spray bar assembly beyond the lateral sides of a vehicle supporting the assembly. The extendable and retractable section includes a manifold tube that carries the asphalt to be sprayed, and which tube is in turn supported on a hydraulic actuator that is used for extending and retracting the associated manifold tube. The manifold tube is provided with a plurality of spray valve assemblies that are operated in a way so that the valves are turned on to permit spraying automatically as the spray bar manifold is extended laterally outwardly, and turn off the spray for the respective valve assembly as the manifold tube is retracted.
