OVER-STABILIZED BITUMEN EMULSIONS MADE FROM EMULSIFIERS FOR SLOW-SETTING EMULSIONS

Formulations of road over-stabilized cationic bitumen emulsions with orthophosphoric, sulfuric and hydrochloric acids and cationic emulsifiers for slowly disintegrating emulsions have been designed. The physical and mechanical properties of the manufactured over-stabilized bitumen emulsions and their breaking behavior were determined. It has been established that over-stabilised bitumen emulsions demonstrate good storage stability for 180 days. The obtained results of breaking behavior bitumen emulsions indicate that emulsions based on hydrochloric and sulfuric acid have a shorter fines mixing time and greater mixing stability with cement than emulsions based on orthophosphoric acid. For over-stabilized bitumen emulsions on orthophosphoric acid, the method according to DSTU EN 12848:2020 is not effective, due to the high reactivity of emulsions on orthophosphoric acid during interaction with portland cement.
