Abstract Nowadays, in many industries, including the road industry, solutions are searched for the resources re-use and recycling. Roads are being built or restored every day and asphalt pavement service life depends on several factors, including traffic load, climate and temperature. The main critical factor, determining asphalt service life, is binder, in most cases bitumen. Bitumen is viscoelastic material, ensuring the necessary adhesion with other asphalt pavement components and providing waterproofing and flexibility to the pavement. As organic material bitumen is susceptible to aging under environmental factors and processing temperatures, as well, bitumen properties depends on crude oil source and distillation conditions. The mechanisms of bitumen aging include oxidation, photo oxidation and evaporation of volatile components at elevated temperatures, consequently, adhesion between asphalt pavements components decreases because bitumen has new intermolecular structure [1,2]. In spite of this, according to statistics [3], uses of reclaimed asphalt increases globally, generally, because of contribution to cost reduction and sustainable development. The aim of this study is to characterize properties of bitumen from reclaimed asphalt pavement in comparison to neat and artificially aged bitumen.
