Abstract
It is recognised that the adequacy of bond between an asphalt surface layer and the underlying pavement material is fundamental to good pavement performance. This is even more important in airport pavements where shear forces imparted by braking and turning aircraft are high. Various measures of interface shear resistance are available to characterise the bond between asphalt surface layers. Advanced test methods were developed to measure the shear resistance of the interface between asphalt layers. These methods include monotonic testing in direct shear as well as repeated load testing in inclined shear modes. Test methods were verified on cores recovered from a typical asphalt-interface-asphalt system from an Australian airport. The results were analysed for interface shear strength, modulus and work, as well as fatigue life. The results demonstrated the effectiveness of the test methods developed, as well as the typical interface shear resistance for airport asphalt surface layers. The application of the developed test methods for differentiating between surface delamination and mixture deformation is recommended.
