ABSTRACT:
A device for abrading road markings along a road surface and for collecting the particulate therefrom. The device includes a frame 11 to which is appended a series of independently controllable abrading devices 18A-D capable of independent actuation by an operator in an enclosed selectively positionable cab 15. The abraders are adapted to rotate along the road surface to be abraded and effectively grind the present road markings into particulate. Thereafter, the collection system consisting of a collection tube 20, bag house 21 and disposal hopper 24 creates a suction force through the system through the use of suction fan 22. Accordingly, the abrading particulate is drawn through the collection system into the bag house where it is filtered by internal suspended filters 27 and is ultimately discharged through the use of an appended conveyor 25 into hopper container portion 77.
