Full-time research to improve the understanding of the mechanisms, causes and methods of evaluation for ravelling or grooved and ungrooved airport asphalt, using a combination of laboratory testing and theoretical modelling.
The Australian airport industry has recently developed a performance-based approach to the design of airport asphalt surfaces. Although there are well established test methods for deformation, fracture and moisture damage resistance, there is no current test for asphalt durability with regard to course aggregate ravelling. Importantly, ravelling is the primary distress governing the period between airport runway resurfacing.
To allow further improvement a laboratory test for ravelling propensity is required and must consider both grooved and ungrooved surfaces in aged and unaged condition.
The intended outcomes are an improved understanding of the mechanisms leading to coarse aggregate ravelling, factors that affect ravelling risk, development of a standard laboratory test method, benchmarking the performance of current typical airport asphalt mixtures and evaluation of potential future materials and mixture types.
