What is CRS-70 Bitumen Emulsion?

CRS-70 Bitumen Emulsion is a cationic rapid-setting emulsion with a higher bitumen content than CRS-60, offering faster breaking, superior adhesion, and stronger performance under heavy traffic. It carries a positive electrical charge, bonding effectively with negatively charged aggregates in demanding road construction projects around the world.

CRS-70 Bitumen Emulsion is widely used for road construction, asphalt bonding, and surface treatment applications across global infrastructure projects. Its higher viscosity and binder content make it ideal for heavy-duty road works, patchwork, and repair operations requiring strong bonding between asphalt layers for long-lasting pavements worldwide.

Black Rock Bitumen supplies CRS-70 Bitumen Emulsion manufactured to international ASTM and AASHTO standards, ensuring consistent performance, fast setting, and adhesion in demanding site conditions. Sourced from certified facilities and shipped through our Dubai logistics hub, our CRS-70 Bitumen Emulsion delivers, export-grade quality worldwide.

    Frequently Asked Questions.

    CRS-70 is a cationic rapid-setting bitumen emulsion with higher bitumen content, offering faster breaking and superior adhesion for heavy-duty road works and surface treatments.

    CRS-70 is a cationic rapid-setting bitumen emulsion with higher bitumen content, formulated for fast breaking and quick curing in road construction applications.

    CRS-70 is used in tack coats, surface dressing, spray sealing, patch repairs, and high-traffic road maintenance works.

    CRS-70 contains a higher percentage of bitumen, providing stronger adhesion, faster setting, and better performance under heavy traffic conditions.

    It carries a positive electrical charge, enabling superior bonding with negatively charged aggregates and improved durability of road surfaces.

    Store CRS-70 in clean tanks, away from direct heat, maintain temperatures above 5°C, and avoid contamination to preserve emulsion stability.

    CRS-70 and K1-70 are both cationic rapid-setting grades with similar binder content, but CRS-70 is classified and tested to ASTM/AASHTO cationic rapid-setting emulsion standards typically used for tack coats and surface dressing, while K1-series naming follows a different regional classification system. Confirm with our technical team which grade matches your project's specification requirement.

    CRS-70 is supplied in bulk via heated tanker, IBC tanks, or new steel drums, with a standard supply capacity of up to 25,000 MT/month and production/loading typically completed within 2–4 weeks of order confirmation.

    Yes, CRS-70's higher binder content and fast-breaking properties make it well suited for high-traffic roads, where quick curing and strong aggregate adhesion are needed to minimize construction downtime.
