Abstract
Significant airport pavement research and development is being progressed around the world with the USA being the focal point of such efforts. This has led to a number of new and emerging technologies. There is a strong desire to improve the ability to predict pavement issues and failures prior to their occurrence. To support that desire, the ability to construct instrumented pavements has advanced significantly in recent years. It is now not only technically viable but is also becoming increasingly cost effective and allows the gathering of real time data from within pavement structures. There is also a desire for improved pavement analysis and design. It is expected that as each of the pavement system elements becomes better understood, finite element methods will be implemented to allow a broader range of potential failure modes to be considered by the designer. There has also been a significant increase in internal shear and other stresses in the airport's upper layers, which has led to shear creep type failures. This must be addressed by improved understanding of near-surface stresses and interface durability. In terms of runway friction, a grooving blade has recently been developed and patented in the USA to allow trapezoidal grooves to be cost effectively constructed. These grooves have been shown to exhibit improved performance and are expected to be endorsed by the FAA as an approved alternate to square-cut grooves. Australia contributes little to these efforts. Therefore our challenge is to adapt, where possible, these new technologies to the local environment, conditions, materials and markets.
