Experimental Study on Airfield Used Asphalt Mixture Designed by Superpave Concept

In this study, the Superpave concept was introduced to asphalt mixture design, with an aim of alleviating airport pavement rutting distress. In comparison with the control mixture (currently the typical Marshall mixture is used in airfields) the engineering properties of the Superpave mixture were comprehensively investigated through a set of laboratory performance-related tests in terms of the static bending and flexural fatigue test, raveling test, submerged wheel tracking test, and wheel tracking test. In the two kinds of mixtures, the same modified asphalt binder and local materials were used. For Superpave mixture design, three aggregate gradations, i.e., fine, coarse, and intermediate, were used. Test results found that all superior criteria can be met through the coarse Superpave mixture, which exhibited significantly higher resistance to raveling and rutting, and similar properties in moisture resistance, fatigue, and thermal cracking in comparison with the control mixture. This experimental study therefore gave the encouraging result of viability in further using this coarse Superpave mixtures in airfields for situations where a major concern is rutting.
