CUTTING BLADE STRUCTURE OF THE ROAD CUTTER FOR CUTTING GROOVE OF THE ASPHALT AND THE METHOD FOR REPARING CRACKS OF THE ASPHALT USING IT

摘要

The present invention relates to a cutting blade structure of a rod cutter for cutting a groove on asphalt and a method for repairing a crack of the asphalt by using the same and, more specifically, a cutting blade structure of a rod cutter for cutting a groove on asphalt and a method for repairing a crack of the asphalt by using the same, capable of deeply excavating a repair groove by improving the cross section shape of the cutting blade of the rod cutter for cutting the groove used to repair the crack of the asphalt and easily injecting an sealant into the crack. The cutting blade is characterized by being formed in a T shape including a double layered structure in which an upper blade of which the width is wide and a lower blade which is narrower than the width of the upper blade are included.
