CRS1 Bitumen Emulsion
Bitumen Emulsion CRS-1 is a type of cationic rapid-setting bitumen emulsion specifically formulated for use in road construction and maintenance. It consists of finely dispersed bitumen particles in water, stabilized with cationic emulsifiers, which allow it to set quickly upon contact with aggregates. The rapid-setting property ensures strong adhesion to the aggregate surface, making it ideal for surface dressing, tack coats, and other applications where immediate binding is required. This emulsion provides durability, flexibility, and resistance to water damage, extending the lifespan of pavements and reducing maintenance frequency.
The specifications of CRS-1, such as binder content, viscosity, storage stability, and particle charge, are carefully controlled to meet ASTM standards. Key performance parameters, including penetration, ductility, and solubility in TCE, ensure the emulsion delivers reliable mechanical properties after the water has evaporated and the residue has set. Its rapid-setting behavior, combined with ease of handling and storage, makes CRS-1 a preferred choice for engineers and contractors seeking efficient, long-lasting, and cost-effective solutions for road surface treatment and rehabilitation.
