The current paper describes optimization of the formulations of asphalt concrete roadway protective impregnation compositions based on BND 60/90 bitumen modified with petroleum resin. Physicochemical, technological and operating parameters of the prepared samples of the compositions are investigated.

The paper considered getting fast drying bitumen emulsion and study its main operating parameters of the film drying rate and durability of the emulsion. The optimum ratio of the components of the emulsion "binder" -"solvent" -"water".

This paper presents an analysis of batch and continuous modification modes of BND 60/90 bitumen binder with petroleum resin. Optimal conditions, namely modification time, stirring rate, and the ratio of components were found. The conditions of continuous operation mode were further optimized.
