Abstract

Styrene-butadiene-styrene (SBS) is currently the most popular bitumen modifier. Its weaknesses have become a strong incentive to search for new materials that could modify bitumen in a similar scope as SBS, but would be cheaper and easier to use. The article presents the results of studies of oleic imidazoline — a new generation bitumen modifier. The analysis of the results of laboratory tests allowed for the optimization of its content in bitumen. It has been demonstrated that the new type modifier developed by the authors of the article has a significant impact on physical characteristics of bitumen. Its use results in a significant increase of bitumen plasticity range, both before and after laboratory ageing, and a considerable improvement of bitumen resistance to ageing.
