Breaking behavior of cationic bitumen emulsions

open access: yesIOP Conference Series: Earth and Environmental Science
Abstract The formulations were developed for road over-stabilized cationic bitumen emulsions on hydrochloric acid and cation-active emulsifiers. There were determined the physical-mechanical properties of the bitumen emulsions produced, while special at-tention was paid to the emulsions breaking behavior. There was defined the influ-ence
