Effect of Binder Characteristics on Fatigue of Asphalt Pavement Using an Intrinsic Damage Approach

ABSTRACT This paper presents the results of an experimental campaign of fatigue tests carried on several asphalt concrete mixes. The main goal of this study is to evaluate the effect of binder characteristics on the fatigue resistance of mixes. The intrinsic damage approach developed at the "Département Génie Civil et Bâtiment" (DGCB) is used to determine the damage rate per loading cycle. The results of the study confirm the efficiency of this approach to evaluate the fatigue resistance of mixes and to quantify the effect of changing some mix characteristics on this resistance. This approach is briefly presented and the results of the tests are analyzed and compared. KEYWORDS: FatigueBituminous mixesBinderPavementRoadDamageFailure
