PREDICTION AND CONTROL OF RUTTING IN ASPHALT PAVEMENTS

In this paper a comprehensive research on the deformation behavior of asphalt mixtures is carried out by means of static and dynamic uniaxial creep tests. Based on the test results an effective rheological model is developed to represent the deformation behavior of asphalt mixtures. Model parameters of related asphalt mixtures are determined with curve fitting method. A practical rutting prediction procedure is advanced in terms of both the rheological model and viscoelastic theory. Based on the travel safety analysis of vehicle and the expert consultation the allowable rut depths in asphalt pavements in China are recommended, which are crucial indexes to pavement design and maintenance. The very significant factors influencing rutting in asphalt pavement are investigated, and several effective rutting control measures are suggested. A pavement design procedure regarding rutting is developed.
