EVALUATION OF HMA CRACKING RESISTANCE AS A FUNCTION OF LABORATORY AGING BASED ON THE DIRECT-TENSION TEST (EVALUACIÓN DE LA RESISTENCIA AL AGRIETAMIENTO DE MEZCLAS ASFÁLTICAS EN CALIENTE EN FUNCIÓN DE SU ENVEJECIMIENTO A PARTIR DEL ENSAYO DE TENSIÓN DIREC
Hot mix asphalt (HMA) is a heterogeneous composite material of asphalt-binder, aggregates, air voids, and other additives including lime, fibers, etc., predominantly used for pavement construction. With time, the HMA mix ages, which leads to changes in the material properties and response behavior. This paper documents a laboratory study that was conducted to evaluate the suitability of the direct-tension (DT) test to assess the effects of asphalt-binder aging on the HMA mix fracture properties and cracking-resistance potential. Two dense-graded HMA mixes were subjected to different laboratory aging exposure conditions and then tested with the DT test. From this test, the HMA mix fracture response was characterized in terms of the tensile s... Ver más
