Title: Deformation Control by Aggregate Contact Increment in Asphalt Concrete Mixture
Abstract: This study is to evaluate deformation behavior of asphalt mixtures which were prepared using new aggregate gradations developed to maximize contact among coarse aggregates particles. A gneiss aggregate and an asphalt(penetration grade of ) were used in this study. To minimize drain down of asphalt through the voids of coarse aggregates, to reduce voids, and to stabilize mixture, shredded paper (waste newspaper) was added to the mixture as a fiber. Marshall mix design was performed for selected gradations to determine optimum asphalt contents. Slab specimens were prepared for wheel tracking tests at to evaluate resistance against rutting. The adjusted grade asphalt concrete mixture showed higher resistance against rutting than conventional dense-graded asphalt mixture.
