![]() ![]() MOQ is 1×20 FCL Bitumen CSS1 and differences with SS1īitumen CSS1 is a type of cationic slow-setting bitumen emulsion that is used in road construction and paving applications. Such grades of asphalt emulsions (bitumen SS-1 grade), when anionic, react chemically with portland cement constituents forming a water-insoluble salt and thus possess valuable water-resistant characteristics. Slow-setting emulsions are grades of emulsions that are sufficiently stable to allow mixing with fine or dusty aggregate mineral particles and further processing before setting to a coherent mass. They are also used in various other applications where water repellent surfaces are needed. Asphalt emulsions are widely used in highway construction, surfacing and maintenance. It is using for cold asphalt in cold or humid or sealing. ![]() Thus a balance must be struck.After the electrostatic part of the reaction is complete the emulsion will rely on flocculation and coalescence to complete break.Īfter break is completed the water must still be completely evaporated for the residual Asphalt to achieve full strength. The other mechanism of evaporation is available too but as the emulsion is stabilized this form of break becomes slower. So it is possible to stabilize a cationic emulsion in the same way that makes it a more rapid break. ![]() The size of the charge, or the Zeta potential affects stability,the larger the charge the greater the repulsion, but as the aggregate is negatively charged the higher the zeta potential the more rapid the reaction. Bitumen cationic emulsion CSS1Ĭationic bitumen emulsions CSS1 have a positive charge and hence a direct and very rapid reaction between the emulsion and an aggregate or pavement is possible. This kind of anionic bitumen has more adhesive to building material which is contain lime. Using bitumen SS1 is environmental friendly since any flammable material or kerosene is not used and firing of the bitumen during the usage would be zero. Percentage of emulsifier is 3-5% and total water content is between 30-50%.By adding Emulsifier to bitumen and water we put anionic electron on the material and each particle of bitumen became like as circle with size of 0.001 to 0.01 mm and become floating in water. By adding emulsifier into water and bitumen that is alkaline salt with Ammonium Salt in high speed mixer at ISO condition making bitumen SS1. In normal conditions and without emulsifier the two parts of emulsion SS1 is unstable and quickly will segregate. Usage of anionic emulsion bitumen SS1 is two phases of water and bitumen which is not possible to mix and first inter phase is inside of outer phase.Particle size of emulsion is 0.1 to 5 micron. 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 thickene. Slow setting bitumenīitumen 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. Overall, bitumen SS1 is a versatile and cost-effective product that offers a range of benefits for various applications, including improved adhesion, dust control, and soil stabilization. In dust control and soil stabilization applications, bitumen SS1 can be applied to unpaved roads and other surfaces to reduce dust and improve their load-bearing capacity. It can also be used as a prime coat to prepare the surface of a road for the application of an asphalt layer, and as a fog seal to protect and extend the life of an existing asphalt surface. In road construction, bitumen SS1 is commonly used as a tack coat to promote adhesion between asphalt layers. The resulting emulsion is a stable liquid that can be stored and transported easily, and can be applied to various surfaces using standard application equipment. The “SS1” designation refers to the specific type of slow-setting emulsion, which is anionic in nature.īitumen SS1 is produced by dispersing bitumen droplets in water with the aid of an emulsifying agent. ![]() Bitumen SS1 is a slow-setting anionic bitumen emulsion that is typically used in a variety of applications, including tack coat for road paving, dust control, and soil stabilization. ![]()
