What is CSS-1H Bitumen Emulsion?

CSS-1H Bitumen Emulsion is a cationic slow-setting emulsion containing approximately 57% bitumen, designed for applications requiring longer working time and improved cohesion. Its higher viscosity compared to CSS-1 delivers superior bonding and stability during mixing and placement in road construction projects worldwide.

CSS-1H Bitumen Emulsion is ideal for tack coats, slurry seals, and micro-surfacing applications requiring enhanced adhesion and mix stability. Its high viscosity and slow-setting nature also suit road construction and maintenance projects where extended workability and superior bonding are essential for lasting performance in every climate.

Black Rock Bitumen supplies CSS-1H Bitumen Emulsion manufactured to ASTM D2397 standards, ensuring consistent bitumen content and cohesion in every batch. Sourced from certified facilities and shipped through our Dubai logistics hub, our CSS-1H Bitumen Emulsion delivers dependable quality for demanding road construction projects.

    Frequently Asked Questions.

    CSS-1h is a cationic slow-setting bitumen emulsion with higher viscosity, formulated for enhanced adhesion and improved performance in slurry and micro-surfacing applications.

    CSS-1h is a cationic slow-setting, high-viscosity bitumen emulsion designed to provide superior bonding and stability during mixing and placement.

    It is commonly used in slurry seals, micro-surfacing, cold mix asphalt, and aggregate and soil stabilization.

    CSS-1h has higher viscosity and improved adhesion, making it more suitable for demanding applications and improved mix stability.

    Advantages include enhanced adhesion and cohesion, better mix stability, extended workability time, and suitability for cold application.

    Store CSS-1h in clean, insulated tanks, maintain temperatures above 5°C, and avoid contamination to ensure long-term emulsion stability.

    The "H" in CSS-1h stands for high viscosity/high performance, which slows evaporation and improves binding strength in warmer conditions, giving better durability and more stable coating during application than standard CSS-1.

    Yes, CSS-1h's higher viscosity and enhanced adhesion make it well suited for slurry seal and micro-surfacing work, where fine aggregate mixtures need extended workability and strong bonding.

    CSS-1h is supplied via bulk tanker, IBC tanks, or new steel drums, with a standard supply capacity of up to 18,000 MT/month and typical production/loading of 2–4 weeks after order confirmation.
