Pavement

Recycled asphalt

Surface

Traditionally, airports in Australia have resisted the incorporation of recycled asphalt pavement (RAP) in resurfacing works. However, in 2018 an airport allowed RAP from the temporary construction ramps and the existing surface millings to be incorporated. These RAP materials were considered to be low-risk and medium-risk sources. Statistical analysis of the mixture design, RAP production testing and asphalt production compliance testing were undertaken to determine the potential impact of extending RAP use to include these low- to medium-risk sources in airport asphalt surfacing. It was found that the minor changes associated with the incorporation of RAP were unlikely to be detrimental. However, it was concluded that the mixture design must characterise and reflect the RAP sources, and the asphalt production must monitor the RAP, similar to other raw materials such as virgin aggregate and bituminous binder. Future work should consider extending these findings to other airport surfacing projects in Australia, allowing specification changes in the future.
