“…This may be due to swelling of SBS with maltene portions of bitumen. The butadiene phase of the polymer absorbs the lighter ends of the asphalt and swells as much as nine times its original volume 19–21. This may weaken the interaction between filler and bitumen.…”

Polymer modified bitumen (PMB) is a binder obtained by the incorporation of polymer into the bitumen by mechanical mixing or chemical reaction. This study deals with the modification of bitumen with three types of polymers (LDPE, EVA, and SBS) in the presence of filler (CaCO 3 ). The morphological, mechanical, rheological properties, and thermal conductivity of the PMBs have been analyzed by scanning electron microscopy, tensile testing, melt flow index (MFI) measurements and hot wire method, respectively. The results indicate that the abovementioned properties of PMBs are influenced by polymer and bitumen nature and its composition. The mechanical properties of composites prepared at different temperatures exhibit small differences. In general, the inclusion of polymer increases tensile strength and Young's modulus and reduces percentage strain and MFI values, also, polymer inclusion reduces the thermal conductivity values of the composites.

This chapter focuses on Asphalt ages during construction, transportation, application phases and service life, as well. Exposure of environmental conditions such as traffic and climate is one of the prominent reasons aging in asphalt. The most common mechanism of aging is the degradation in the chemical structure of the binder by oxidation. Asphalt aging could cause several serious issues on the pavement such as stiffening, stripping that accelerates fatigue cracking and different moisture-induced problems such as raveling and potholes. Therefore, various additives are used as modifiers to improve the mechanical properties of asphalt. The most commonly used modifiers are polymers. Styrene butadiene styrene (SBS) polymers are utilized to prevent from deteriorating against external factors during its service life and to delay its aging in asphalt pavement. In the scope of this study, it was aimed to provide the general perspectives on mechanical characteristics of multi-layer asphalt structure under the aging effects besides traffic conditions.
