Black Rock Bitumen is a trusted K1-40 bitumen emulsion supplier in Dubai, delivering high-performance cationic bitumen emulsion for road construction, surface dressing, and maintenance applications worldwide. We provide bulk export supply of K1-40 bitumen emulsion with SGS inspection, COA documentation, and flexible FOB/CIF shipping — ensuring consistent quality and reliable delivery for contractors, EPC companies, and government procurement agencies.
Bitumen Emulsion K1-40 is a cationic, rapid-setting emulsion containing a minimum of 40% bitumen dispersed in 60% water with emulsifying agents. Cold-applied and compliant with BS 434 Part 1, it forms a thin, uniform bitumen film that bonds pavement layers after curing in road construction projects across diverse climate conditions and terrians.
Bitumen Emulsion K1-40 is widely used as a tack coat to bond existing pavement surfaces with new asphalt overlays, including hot rolled asphalt and macadam. It also suits mist spraying, concrete curing, chip seals, and prime coats in road construction, maintenance, and highway repair projects worldwide, making it a versatile and a cost-effective choice.
Black Rock Bitumen supplies Bitumen Emulsion K1-40 manufactured to BS 434 and MS 1.61 standards, ensuring consistent bitumen content, viscosity, and setting performance in every batch. Sourced from certified facilities and shipped through our Dubai logistics hub, our Bitumen Emulsion K1-40 delivers dependable, export-grade quality worldwide, every time.
We deliver bitumen in versatile, secure options: economical Jumbo Bags, robust steel Drums, or high-volume Bulk Containers (Bitutainers/Bituboxes).
K1-40 is a cationic slow-setting bitumen emulsion formulated for slurry seal and surface treatment applications, offering good workability and strong aggregate bonding.
K1-40 is a cationic rapid-setting bitumen emulsion with 38–42% binder content, produced by dispersing bitumen in water with a positively charged emulsifier. It bonds quickly with negatively charged aggregates, enabling cold, no-heat application in road construction.
K1-40 is used for prime coating, surface dressing (chip sealing), dust control on unpaved roads, and routine road maintenance and patch repair work.
K1-40 has a lower binder content (38–42%) than K1-60 (around 58–62%), making K1-40 better suited to prime coats and dust control, while K1-60 is typically used for tack coats and surface dressing needing a higher residual bitumen film.
K1-40 should be stored in clean tanks between 5°C and 50°C with periodic gentle agitation to prevent settling, and protected from freezing. Typical shelf life is 3–6 months when stored correctly.
No. K1-40 is applied cold, which reduces energy costs and improves job-site safety compared to hot-applied bitumen.
Black Rock Bitumen supplies K1-40 in jumbo bags, steel drums, and bulk containers (bitutainers/bitubox), depending on shipment volume and destination port requirements.
Standard supply capacity is 1,000–2,000 metric tons per month, with lead times of 2–4 weeks depending on order volume and shipping terms (FOB, CFR, or CIF).
Yes, every shipment can be inspected by independent third parties such as SGS, Geo-Chem, or Bureau Veritas, with a Certificate of Analysis (COA) provided against ASTM D244, D6933, D113, and related test methods.
