Tearing it up
RAF MILDENHALL, England -- Carl Scarfe, a local contractor, removes worn teeth from underneath a road planer in Washington Square here. While grinding up concrete from the old parking lot, the teeth degrade and must be replaced periodically. This road planer removed more than 1,500 tons of concrete in only a few days during the initial stages of construction that will transform the square into a pedestrian area.
