“…The investigations (Sidun, 2019) also assert the expediency of using ortho-phosphoric acid both for the cationic bitumen emulsions and Slurry Surfacing (Sidun, 2020).…”

“…In general, Slurry Surfacing technology in the developing countries is not wide-spread due to a number of reasons: to reach the standard ratios it is necessary to use the expensive high acid import bitumen; during emulsion production they use rather aggressive hydrochloric acid (НСІ), which can lead to equipment damage and requires obtaining license for dealing with precursors; when working with hydrochloric acid the higher labor safety level shall be guaranteed for the staff. Therefore, the usage of hydrochloric acid not only leads to the rise of technology cost, but also demands the entire chain of additional technological modifications both with regard to the working place for the staff and the production equipment both when it is installed and during its operation (Pyshyev, 2015;Sidun, 2020) .…”

“…In (Sidun, 2019) it is stated that the main difference in physical-technical indices of emulsions on hydrochloric and ortho-phosphoric acids consists in the lower values of breaking index and emulsion pH, while it means higher reactivity of this emulsion. The worse indices of stability during storage mean (in emulsions on ortho-phosphoric acid) the possibility of worse bitumen emulsification during the emulsion production, i.e.…”

“…In spray applications the emulsion is used for surface dressing (chip seal), fog seal, scrub seal, graded aggregate seal, tack coat, prime coat, penetration macadam and dust control. In mix applications it is used for slurry seal, microsurfacing, cape seal, open-graded cold mix, dense-graded cold mix, soil stabilization, pre-coated chips, stockpile mix and recycling asphalt pavement (RAP) ( Sidun, 2019).…”

In this article the cationic bitumen emulsions are characterized-as popular binder for various road emulsions. There are considered the specific features of cationic bitumen road emulsions' formulations. There are presented the functions and specificities of the acids application in cationic bitumen road emulsions. The literary review is presented on potentialities of ortho-phosphoric acids application instead of the traditional hydrochloric acid. Chemical peculiarities of application are presented (as well as advantages and drawbacks of application)-for both the traditional hydrochloric acid and forward-looking ortho-phosphoric acid. As the advantages of ortho-phosphoric acid application for cationic bitumen road emulsions one can mention: simple replacement of acid in soap solution preparation, less corrosive acid, higher pH emulsions, acid is easier to store, fewer fumes, not regulated in some countries, unlike hydrochloric acid. The potentialities are considered for application of ortho-phosphoric acid, as an effective component of cationic bitumen emulsion for application in various bitumen emulsion technologies, including the technologies for making protective slurry road pavements, among which the most widespread application was found by ortho-phosphoric acid in special fast-setting Slurry Surfacing systems, which possess a number of advantages over the same systems based on hydrochloric acid. The main of those advantages are as follows: such application eliminates the need for acid dopes in bitumen, provides a quick-traffic slurry system that works in cooler temperatures and at night, no need to change the usual latex or SBS grades, can use normal break retarders, mix controllable with cement in the field.

“…The emulsions allow to work under adverse weather conditions, when it is impossible to achieve the required quality of work using hot mixtures even in the presence of surfactants. But there are also some drawbacks of using BE: the possibility of emulsion washing-out during prolonged rains; the final formation of coatings under the influence of motion is slower than that using the hot method; the coating formation requires particularly diligent care [1][2][3].…”
