Two machines have been developed to eradicate old traffic lines. The MacDonald Scabbler, a pneumatic power tool, employs 11 cutting bits, each having 9 carbide insets. The rotating heads compress the line area, and when the pressure is released, small pieces of concrete are expelled from the road. In light traffic areas the Scabbler can remove pavement markings for 13 cents per linear foot. The Hydroblaster consists of a high-pressure water pump powered by either a gasoline-driven or an electric motor. In line removal both abrasive materials and pressurized water are used. The cost is 22 cents per foot. It can also be used for cleaning metals and creating exposed aggregate concrete. The long train of equipment may be a hazard on busy highways, but the effectiveness and versatility of the Hydroblaster seem to outweigh its disadvantages. /HRIS/
