Comparison and Evaluation of Fatigue Behavior of Asphalt Concrete Mixtures Containing Different Recycled Additives

Fatigue phenomenon is one of the most important mechanisms of failures in road pavement which is caused by repeated loading. In recent years, the use of recycled additives such as crumb rubber, tire thread, waste iron and waste glass are taken into consideration in order to improve the properties of bitumen and consequently, improve the properties of asphalt mixtures. Also, the use of these recycled additives prevents their distribution in the nature. In this study, the effects of different recycled additives have been evaluated on the fatigue parameters of asphalt mixtures. The results of this study showed that adding 5% waste tire thread to the asphalt concrete mixtures causes the highest fatigue life, increasing stiffness and the least amount of strain while failure than the other recycled additives such as waste iron, crushed glass and aromatic oil.
