What is RS-1 Bitumen Emulsion?

RS-1 Bitumen Emulsion is an anionic, rapid-setting emulsion containing a minimum of 57% bitumen dispersed in water with a negatively charged emulsifier. Its low viscosity and fast breaking action provide excellent adhesion, particularly with alkaline aggregates such as limestone, in road construction and maintenance applications worldwide today.

RS-1 Bitumen Emulsion is widely used as a tack coat to bond existing pavement surfaces with new asphalt overlays, ensuring strong adhesion and preventing slippage. It also suits chip seals, surface dressing, and prime coats, providing a protective, skid-resistant layer for road maintenance and repair projects across diverse regions.

Black Rock Bitumen supplies RS-1 Bitumen Emulsion manufactured to ASTM D977 standards, ensuring consistent bitumen content and setting performance in every batch. Sourced from certified facilities and shipped through our Dubai logistics hub, our RS-1 Bitumen Emulsion delivers export-grade quality for road construction projects worldwide.

    Frequently Asked Questions.

    RS-1 is an anionic rapid-setting bitumen emulsion designed for surface dressing and spray seal applications requiring quick breaking and efficient aggregate adhesion.

    RS-1 is an anionic rapid-setting bitumen emulsion with low viscosity, formulated to break and bond quickly with aggregates and pavement surfaces.

    RS-1 is widely used for tack coats, prime coats, surface dressing, and patch repair work, particularly where fast bonding and quick reopening to traffic are needed.

    RS-1 has lower viscosity and binder content than RS-2, making it better suited to tack coats and lighter applications, while RS-2 forms a thicker film suited to chip sealing and heavier surface treatments.

    Yes, RS-1 is a cold-applied emulsion, which reduces energy costs and improves job-site safety compared to hot-applied bitumen.

    RS-1 performs best on dry surfaces since it is an anionic emulsion; for damp or humid conditions, a cationic rapid-setting grade is generally preferred.

    No, RS-1 is not suitable for mixing since it breaks too quickly and may cause clogging; it's intended for spray applications like tack coats and surface treatments.

    RS-1 should be stored in clean tanks, kept above 5°C, protected from contamination, and applied using suitable spray equipment.

    Yes, RS-1 is supplied in bulk from Black Rock Bitumen's Dubai facility under FOB, CFR, or CIF terms, with SGS/Bureau Veritas inspection available on request.
