A pavement cutter that saves construction materials and prevents repaired pavements from subsiding or collapsing includes a first tilting mechanism attached to a front wheel axis as a base for a tilting mechanism where the base chassis tilts around the rear wheels without restraint; a frame where a spherical shell disk, its rotating axis and a driving unit are mounted is rotatably connected to one side of the base chassis via a hinge, a second tilting mechanism to move the spherical shell disk upward/downward and a cutting circle determining mechanism to determine a cutting radius and its center, where circular or straight cuttings are attained by exchanging the spherical shell disk to the flat disk and vice versa.
