What is CMS-2 Bitumen Emulsion?

CMS-2 Bitumen Emulsion is a cationic medium-setting emulsion containing approximately 65% bitumen dispersed in water with emulsifying agents. Its controlled setting time allows proper mixing and coating of aggregates before breaking, making it ideal for plant mix and site mix asphalt applications at ambient temperatures worldwide.

CMS-2 Bitumen Emulsion is widely used in cold mix asphalt production, patching, and road maintenance applications requiring longer mixing time before setting. It ensures proper aggregate coating and effective bonding, delivering durable asphalt mixtures and long-lasting repairs across global construction and infrastructure projects in every climate

 Black Rock Bitumen supplies CMS-2 Bitumen Emulsion manufactured in compliance with ASTM D2397 and AASHTO M208 standards, ensuring consistent bitumen content, viscosity, and setting performance.

    Frequently Asked Questions.

    CMS-20 is a cationic medium-setting bitumen emulsion designed for premix applications, offering controlled breaking and strong aggregate coating.

    CMS-2 is a cationic medium-setting bitumen emulsion that allows sufficient mixing time before setting, ideal for premix and repair works.

    It is used in open-graded premix carpets, patch repairs, and cold mix applications, especially where uniform aggregate coating is required.

    CMS-2 breaks at a moderate rate, providing adequate time for mixing and laying before the emulsion sets.

    Key benefits include good workability, excellent aggregate coating, suitability for cold applications, and reduced energy consumption compared to hot mixes.

    Store in clean containers, protect from extreme temperatures, keep above 5°C, and avoid contamination to maintain stability.

    CMS-2 is a medium-setting grade formulated for extended mixing time in cold mix and premix asphalt applications, while CRS-70 is a rapid-setting grade designed to break quickly for tack coats and surface dressing. Choose CMS-2 when workability and mixing time matter more than fast curing.

    Yes, CMS-2's controlled breaking behavior and approximately 65% bitumen content make it well suited for plant mix and site mix cold asphalt production, where uniform aggregate coating is essential.

    CMS-2 is supplied via bulk tanker, IBC tanks, or new steel drums, with a standard supply capacity of up to 20,000 MT/month and production/loading typically completed within 2–4 weeks of order confirmation.
