Bitumen emulsion SS1 is slow-setting, anionic type and are further characterized by their ability to remain stable on storage although produced with equipment that generates a wide range of shearing forces. Such characteristics are imparted to the asphalt emulsions through the use of emulsion-conditioner compositions comprising a partially desulfonated lignosulfonate, preferably an anionic or nonionic emulsifying agent and, optionally, a thickened.
Usage of anionic emulsion bitumen SS1 is two phases of water and bitumen which are not possible to mix and the first interphase is inside of outer phase. The particle size of emulsion is 0.1 to 5 micron. In normal conditions and without emulsifier the two parts of emulsion SS1 is unstable and quickly will segregate. By adding emulsifier into water and bitumen that is alkaline salt with Ammonium Salt in high-speed mixer at ISO condition making bitumen SS1.
