Shulgin State Road Research Institute State Enterprise popup.description2  The object of the study is additives based on surfactants and materials based on them. The purpose of the study is regulatory provision of the road complex in terms of technical requirements and methods of testing the additives based on surfactants for paving bitumen. The methods of research are experimental studies based on surfactants and materials based on them. A review of the literature on the use of additives based on surfactants to improve the properties of bitumen and materials based on them was carried out. The technical properties of additives based on surfactants were determined, namely: density, dynamic viscosity, conditional viscosity and adhesive activity. The thermostability of additives based on surfactants was investigated by determining the change in adhesion of modified bitumen with crushed stone during thermo-aging and thermo-oxidative aging. The impact of additives based on surfactants on the properties of bitumen and asphalt concrete was established. During work performance, it was developed, approved and directed to the adoption in accordance with the established procedure of DSTU "Additives based on surfactants for paving bitumen. Specifications". Product Description popup.authors Kopynets Ivan V. Sokolov Oleksii V. Sokolova Oksana B. Yunak Alina L. popup.nrat_date 2020-04-02 Close
