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 skid resistance requirements. Closure of the grooves is a common distress experienced at airports surfaced with DGA in Australia and 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. This paper summarises the research to validate SMA as an alternate runway surface for Australian airports, including laboratory performance testing and a subsequent field trial. A performance-based specification for SMA has now been developed and will undergo validation in the Australian airport context.
