The object of investigation is bitumen road emulsions. The article deals with the main quality indicators of bitumen road cationic emulsions (EBDC) produced on semi-automated installations KATION-10. Current studies of existing techniques for the preparation of bitumen emulsions are analyzed. Studies of EBDK-B and EBDK-M made on various emulsifiers have been carried out. The obtained experimental data are analyzed. The most effective technological solutions for providing the required quality of bitumen road cationic emulsions have been identified.
