The US Air Force has over 170 operational airfield facilities and missions that take them to all seven continents of the world. The special operational requirements of the Air Force and the breadth of environments in which it must operate has sometimes posed unique design requirements. This paper will examine a series of case studies of special design problems that had to be addressed or if not addressed, the impact of failing to adequately address these issues. The specific issues and case studies to be examined will cover: trafficability during construction; understanding site conditions; very soft reclaimed land; operations in perennially frozen conditions; sulphates and their unexpected impacts; material control to achieve desired performance; and long life pavement concepts. For the covering abstract see ITRD E139491.
