These surfaces are generally replaced by asphalt overlay every 10-15 years. Airport asphalt surfaces are highly suited to sprayed surface preservation treatments. There are a range of treatments to preserve and extend the life of asphalt surfaces. These generally replace lost binder and/or fine mineral material. These treatments generally create a temporary protective coating over the existing surface. A number of new materials have largely replaced the traditional coal-tar based and cutback bitumen products. These new materials are emulsion based and often include polymers. This paper presents a summary of experience and new materials for treatment of asphalt surfaces at Australian airports. Oxidation retarders and surface filling treatments are explored, as well as fuel resistant membranes. A number of lessons learnt are presented and a whole of life approach is undertaken in considering future opportunities.
