The use of additives is one of the effective techniques adopted to improve pavement properties. Recently, hydrated lime has been categorized as a major additive in asphalt pavement because of its wide availability and relatively cheap cost. The main purpose of this study is to quantify the effect of hydrated lime on asphaltic concrete performance under varied temperatures of weather and in the application of different pavement courses, i.e. wearing (or surface), leveling (or binder), and base. Five different percentages of the hydrated lime additive, which were used as partial replacement of the conventional limestone filler, were investigated. Tests were conducted to evaluate the resistance to the Marshall stability, and the volumetric properties, the resilient modulus, and permanent deformation at three different temperatures. The experimental results have shown an expected improvement on the mechanical properties for all the designed asphalt concrete mixtures when using hydrated lime additive. The optimum hydrated lime contents for different course applications have been suggested.
