HYDRAULIC SANDBLASTING OF PAVEMENT STRIPING

A method of hydraulics and blasting is described which can minimize or elimate many problems associated with conventional sandblasting or other methods of striping obliteration. The procedure involves the use of the Hydroblaster which consists of a high-pressure water pump powered by either a gasoline engine or electric motor, and is mounted on skids or a 2-wheeled trailer. A hand-held wand and an abrasive tank are included. An independent water source which is clean and under 60 to 100 psi pressure is required. Details of the pump and the rest of the unit are described. This machine, which should be operated only by qualified personnel, removes striping with a minimum of asphalt removal and no polishing. The water washes out the voids so the operator can see when all the paint is gone. A 2-man crew can average over 270 feet of striping removal per hour. Because there are no dust problems or excessive flooding, striping can be removed with minimal disturbance to adjacent traffic.
