High-Performance High Float Anionic Medium Setting Emulsion for Heavy-Duty Roads
Black Rock Bitumen supplies HFMS-2H bitumen emulsion, a high-performance high float anionic medium-setting emulsion engineered for maximum strength, superior bonding, and long-lasting durability in demanding infrastructure projects.
Manufactured to meet ASTM D977 / ASTM D244 standards, HFMS-2H is widely used in heavy-duty cold mix asphalt, road rehabilitation, base stabilization, and high-load traffic applications.
What is HFMS-2H Bitumen Emulsion?
HFMS-2H (High Float Medium Setting – Grade 2 High Performance) is an anionic bitumen emulsion designed to deliver a thick, highly durable, and flexible bitumen film, optimized for high-load and long-life pavement applications.
Key characteristics:
- High float property → produces a thick, gel-like binder film
- Medium setting behavior → allows proper mixing before curing
- “H” grade (High Performance) → improved viscosity, bonding, and durability
- Negative charge (anionic) → best suited for calcareous aggregates
The “H” designation indicates enhanced performance, including stronger adhesion, deeper penetration, and improved resistance to cracking and deformation
Unlike standard HFMS-2:
- Provides stronger film strength and cohesion
- Offers greater resistance to heavy traffic stress
- Ensures longer service life in extreme conditions
