Abstract
Flexible airport pavements in Australia have traditionally been surfaced with Marshall-designed dense graded asphalt (DGA). Grooving is undertaken on runways to avoid aircraft skidding incidents during wet weather conditions, as well as satisfying regulatory surface texture requirements as set by Australia's Civil Aviation Safety Authority (CASA). Groove closure is a common distress experienced at airports surfaced with DGA in Australia, inhibiting the pavement's ability to shed water, ultimately increasing the risk of hydroplaning. Repairing of grooves is costly and effects the operational capability of an airport for the period of repair works. Consequently, this has led to the investigation of stone mastic asphalt (SMA) as an alternate runway surfacing. Due to the gap-graded nature of SMA, and therefore increased surface texture, grooving can be avoided. SMA is commonly used internationally as a runway surface due to its high rut resistance, increased fatigue resistance and coarse texture. In Australia, SMA has been employed on roads as a premium product for heavy duty traffic. The use of SMA on Australian airport pavements is extremely limited with only two airports undertaking non-runway trials in the recent past, with mixed results. The confidence for Australian aerodrome operators to employ this material is low as the solution has neither been translated or validated for Australian airports. This research aimed to perform that validation.
