Anotācija Bitumen has been used as road construction material already since ancient times, just to mention Babylon “Procession Street” as only one example [1]. Since then uses of bitumen in road construction have been vastly extended. According to the recent information of the Eurobitume – a forum for businesses pertaining to the European bitumen industry – the European bitumen industry (EU 28) produces approximately 15 million tons each year from which the majority (85–90 per cent) is used in the construction and maintenance of bituminous or asphalt roads [2]. To cope with increasing stresses of traffic loads, environmental pollution, increased carbon dioxide levels caused global temperature rise there is a necessity for bitumen modification to increase its durability and extend performance range. Among different approaches, bitumen modification with thermoplastic elastomers, particularly, styrene-butadiene-styrene copolymer (SBS), has been demonstrated to be successful in increasing durability, including low-temperature (fracture resistance) and high-temperature (rutting resistance) performance [3]. By considering high price of SBS, constantly various alternatives of polymer modifiers are sought for to improve both low-temperature and high-temperature properties of bituminous materials in spite of the complexity of this multi-factorial problem.
