Abstract
A hard surface roadbed profiler designed to perform a repetitive drill hole collaring cycle. By generating a series of interconnected collar holes, an extended flat surface is created. The profiler includes a movable percussive device mounted onto a chassis. A flat faced bit is attached to the percussive device to create the individual collars that are linked together to form a flat array.
