Abstract (en)
[origin: WO2020221980A1] The present invention relates to the use of an aqueous dispersion comprising at least one anionic surfactant and particles π1 of at least two polymers having separate glass transition temperatures, such that the polymer having the highest glass transition temperature, greater than or equal to 10°C, is at the centre of the particle π1, and the polymer having the lowest glass transition temperature, less than or equal to 0°C, is on the surface of the particle π1, for the preparation of a binder intended for the production of a coated macadam for roads and cities.
