Abstract
This article describes the classification of cationic bitumen emulsions according to "reactivity" and breaking behaviour characteristics. The methods of researching the characteristics of breaking behaviour for bitumen emulsions of different "reactivity" in accordance with European and Ukrainian regulatory documents are presented. Available possible emulsifiers in Ukraine for over-stabilised bitumen emulsions are given with a description of road technology where they can be applied. The experience of using over-stabilised bitumen cationic emulsions in road construction is characterized. Namely, a literature review of the use of over-stabilised bitumen cationic emulsions in soil stabilization technologies, strengthening of base course materials with emulsion, and "cold recycling" technology was carried out. The regularities of the interaction of over-stabilised bitumen emulsion with finely dispersed mineral binders and fillers are reviewed.
