In Australia, seals have been used for many years at airports with aircraft of Boeing 737 and up to Boeing 767 in size, even though asphalt is mainly used as the surfacing on heavy duty airport pavements for airline jet aircraft. The selection and design of seals for heavy duty airport pavements differs from seals for roads in a number of important ways. The suitability of airport pavements for sealing varies, and seals are not a universal substitute for asphalt. There are operational requirements to be met in terms of texture and friction, which affect the selection. The seal design method is adjusted to reflect airport trafficking. The choice of binder and aggregate is somewhat different from highway seals. Construction and maintenance are generally similar to that on roads, with differences in rolling and ongoing maintenance of seals on airports.
