OVERVIEW: THE DIFFERENCES BETWEEN AIRFIELD PAVEMENTS AND ROADS

This paper describes how airfield pavements must facilitate safe aircraft ground operations. This in turn necessitates special design considerations with respect to several key functional requirements. The structural design and evaluation of airfield pavements can involve wheel loads up to 28 tons and arranged in various multiple configurations. Surface serviceability requirements can necessitate special considerations in respect of material specifications, construction and maintenance of airfield pavements. This includes the need for high friction levels to facilitate effective and efficient braking and steering of aircraft at high speeds and in wet conditions. Aircraft are also susceptible to damage from loose materials on a pavement surface. These potential sources of damage are generally referred to as an FOD (Foreign Object Damage) hazard. Safeguarding against the FOD risk therefore necessitates airfield pavements having high surface integrity. A further complicating factor is the difficulty of gaining access to carry out maintenance on airfield pavements especially on a runway. Other special design requirements can include resistance to fuel spillage, de-icing chemicals and jet blast. The design and serviceability requirements together with the potentially serious consequences of failure necessitate a separate approach to the design, construction and maintenance of airfield pavements. This paper will provide an overview of some of the key engineering issues, highlighting differences and synergies between airfield pavement and road works.
