Adhesion of Road Bitumen Emulsions on Both Hydrochloric and Orthophosphoric Acids for the Technology of Surface Dressing

Abstract

This article presents the review of surface dressing wear courses, being the version of preservation and sealing of road structures' top layers. In the article, there is studied the adhesion of aggregates (from various granite quarries of Ukraine) with a bitumen binder, namely bitumen emulsion, for application in surface dressing for road pavements. In the article, there are used both the Ukrainian and European testing methods for the determination of adhesion in the bitumen-aggregate system. There was developed two bitumen emulsion formulations for the thin-layer motor-road pavements by the surface dressing depending on the type of acid used (either hydrochloric or orthophosphoric).

Cationic over-stabilised bitumen emulsion in road construction - review

“…The technology of cold in-plant recycling involves transporting the finished mixture to the construction site, so it is necessary to ensure the immediate placing of the mixture. In addition, in these technologies it is possible to use a composite binder of bitumen emulsion and cement, and over-stabilised emulsions show good miscibility with cement (Grilli, 2012;Grilli, 2013;Grilli, 2018;Grilli, 2016;Pasetto, 2020;Sidun, 2022;Ouyang, 2018;Baldo, 2021;Vollis, 2017;Romeo, 2018;Garilli, 2019;Godenzoni, 2018).…”

“…Therefore, rapid-setting emulsions are used with non-reactive aggregates with a small surface area, and slow-setting ones are used with reactive aggregates with a large surface area. As for road technologies, as a rule, CRS is used for surface treatments, CMS for mixtures of porous grain composition, and CSS for dense mixtures according to their grain composition (Grilli, 2012;Grilli, 2013;Grilli, 2018;Grilli, 2016;Pasetto, 2020;Sidun, 2022;Ouyang, 2018;Baldo, 2021;Vollis, 2017;Romeo, 2018;Garilli, 2019;Godenzoni, 2018).…”
