APPLYING DEVICE FOR SURFACE TREATING

An applicator for mounting on a vehicle for applying a surface treatment of tar and/or bituminous binder material reinforced with glass fibres, such an applicator comprising an open bottomed spray bar housing (1), a fan (16) for producing a downdraft in the housing, at least one spray bar (5,19) mounted on said housing and adapted to extend transversely of the direction of movement of the vehicle on which the applicator is mounted, a plurality of nozzles (6,20) spaced longitudinally along the spray bar for spraying binder material, means (10) for controlling said nozzles, a plurality of sources (14, 24-28) for dispensing cut glass fibres through said open bottomed housing to the surface of binder material previously sprayed from the spray bar nozzles during use of the applicator, said sources being mounted at locations spaced along a plane substantially parallel to said spray bar, such that the glass fibres are dispensed substantially evenly onto the surface of binder material previously sprayed from the spray bar nozzles.
