  • Patent number: 5842747
    Abstract: An apparatus for a roadway surface reclaiming drum is disclosed that includes a plurality of flighting sections generally helically attached to a cylindrical surface of the drum at an included angle of about 40.degree. to about 60.degree.. During rotation of the drum about its cylindrical axis, a plurality of cutter bits mounted to openings defined in the flighting sections loosen roadway surface and the flighting sections transport loosened roadway material axially along the drum and between the flighting sections towards a lateral center portion of the drum. A plurality of teeth received in recesses defined in walls of the flighting sections facilitate transport of loosened roadway material between adjacent flighting sections towards the lateral center portion of the drum and reduce wear of the flighting sections. Cutter bit inserts for receiving the cutter bits are mounted to base portions attached to the outermost portions of the flighting sections, and define interior bores.
