When cutting pavement in very cold winter weatherit is sometimes necessary to put a load on the car toprevent the cutting tool from riding on the pavementsurface. It was found that the best cutting tools werethose forged from old carbon steel gads. These weresuperior to high-speed steel. The tool becomes dulledand requires to be replaced after cutting about 600 the summer time or 300 to 400 ft. in the winter time. The design of the cutter was worked out by W. , principal assistant engineer. B. P. Legareis engineer of maintenance of way. Convenient Test Bo
