ABSTRACT:

According to the performance properties of the bitumen-polymer coatings we assumed the need of their physico-chemical modification: to plasticize and exception thus oxidative degradation, i.e. premature aging, and in order to achieve high adhesion strength properties. Film-forming materials based on saturated plant oil and elemental sulfur possess needed bifunctionality. The complex of investigations to determine the degree of physical and chemical interaction between sulfur and saturated plant oil during heat treatment, mechanical activation and oxidation was carried out. The optimal and limiting amount of sulfur entrained into oil was determined. The basic chemical reactions that take place with the participation of sulfur in implementation of the process at low temperatures were clarified. It was found, that at relatively low temperatures (in the physico-chemical treatment) sulfur gives greater flexibility and ductility.
