Comparative assessment of the mechanical properties of asphalt layers under the traffic and environmental conditions

Abstract

It is necessary that the asphalt concrete coating, which is prepared with Hot Mix Asphalt (HMA), shows the expected performance along their service lives and sustain their endurance against traffic and climate conditions. It is also necessary to use additives in order to ensure long service lives because the raw material is scarcely available. Polymers have been widely used in HMA as additives in recent years. The use of Styrene Butadiene Styrene (SBS) polymer materials in HMA mixtures come to the front line among the additives. In this study, the behaviors of the super structure of the roads, which were prepared with pure and SBS-modified additive HMA mixtures, in various traffic and climate conditions and in a sample road platform within one year in various periods were examined in order to understand the mechanical properties of HMA. In the scope of the study, empirical and numerical studies have been considered. The physical and mechanical properties of the layers (coating, base and sub-base) that constituted the super structure of the road have been examined in an empirical manner by considering the field and laboratory works.
