In the article there is proved the possibility of using ortho-phosphoric acid with special emulsifiers instead of hydrochloric acid - for the production of road cationic slow-setting bitumen emulsions. There is ascertained the difference between used for bitumen emulsions distilled binder (Nybit E85 bitumen), produced from heavy crude oil, and oxidized bitumens (grade 70/100 bitumen produced by JSC Mozyr Refinery and grade BND 60/90 bitumen of JSC UkrTatNafta), produced from light crude oil. The difference is analyzed between physical-mechanical indices of distilled and oxidized bitumens. Eight bitumen emulsion formulations were developed based on usage hydrochloric acid, three bitumens and three emulsifiers (Redicote E-11, Redicote 404 and Redicote E-4875), as well as four formulations based on usage of ortho-phosphoric acid, two bitumens and two emulsifiers (Redicote EM44 and Redicote C-320). There was investigated the influence of hydrochloric and ortho-phosphoric acids upon the physical-technical indices of road cationic slow-setting bitumen emulsions and the difference was ascertained between the indices of bitumen emulsions based on distilled and oxidized bitumens. Bitumen emulsion formulations were developed based on usage of ortho-phosphoric acid and special emulsifiers for the class of cationic slow-setting emulsions for slurry seal and microsurfacing mixtures.
