Research of Fatigue Behavior of Asphalt Pavement Materials with WMA and RAP

Abstract:

With the development of chinas road construction, the increase of traffic and the traffic load the fatigue of asphalt pavement under the vehicle load has become one of the major disruption in the form of life of life of asphalt concrete directly affect the service life and the performance use of asphalt pavement ,it is a key factor to determine the life cycle cost of asphalt concrete pavement construction. The objectives of this paper are to characterize the fatigue behavior of porous asphalt pavement mixtures containing RAP and a WMA additive using Super pave gyratory compactor and dynamic modulus testing. Four types of asphalt mixtures were evaluated in this study. This study evaluated compaction energy index, permeability, indirect tensile strength, and dynamic modulus for all types of porous asphalt mixtures. All of the asphalt mixtures meet the typical minimum coefficient of permeability in this study.
