Transportation today plays a unique role connecting all the most important areas of material production into one system. Tendencies and prospects for bitumen modifications based on polymer additives, improving properties of bitumen and concrete, are considered in the article. When high quality BPC (bitumen polymer composites) materials are used, extensive repairs are required (in the worst case scenario) only after 5 years, as a result of the increase in the service life of roads by the factor between 2 and 5. The impact on the environment as well as maintenance expenditures are decreasing. Bitumen-polymer composites are ecologically clean when compared with the traditional ones
