Late last year—working nights under very tight time constraints— a Wirtgen W 2200-12 cold mill with 12-ft 6-in.-wide drum worked with smaller Wirtgen mills to remove asphalt from a main runway at Ronald Reagan Washington National Airport (DCA). There the W 2200-12, Wirtgen's then-largest mill, expedited milling of Runway 1-19 plus tie-backs into all adjoining taxiways, a total of nearly 300,000 sq yd. When visited, milling contractor Mark-Lang Inc. was removing the intersection of runways 1-19 and 15/33.
