Abstract

Civil Engineering Transportation and Freight Services cutback emulsions friction rejuvenators whole life costing
Many airport surfaces in Australia are constructed of dense graded asphalt. 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
