Bitumen Emulsion HFMS-1 is typically using where penetration into aggregates is needed but not too fast, giving better coating and durability. This Type of Emulsion Bitumen is producing in Asia Bitumen factory according to the clients order.
Bitumen Emulsion HFMS-1
Description
Bitumen Emulsion HFMS-1 refers to a High-Float Medium-Setting (HFMS) cationic or anionic bitumen emulsion used commonly in road construction and maintenance.
What is HFMS-1 Means
H = High
F = Float (refers to the “high float” property that allows a thick, durable binder film)
M = Medium Setting (breaks sets at a moderate rate, suitable for controlled mixing)
S = Setting
1 = Lower viscosity grade within the HFMS series (HFMS-1, HFMS-1h, HFMS-2, HFMS-2h)
Characteristics
High float property: forms a thicker, more resilient asphalt film which improves performance in hot climates.
Medium-setting: allows mixing with coarse aggregates without premature breaking.
Water-based emulsion: easier to apply, safer to handle, and environmentally friendly compared to cutback asphalt.
Good coating ability: suitable for open-graded aggregates.
Enhanced durability: resists stripping and deformation.
Main Uses
HFMS-1 is commonly used for:
Penetration macadam (PM) work
Surface dressing chip seals
Road repairs and patching
Seal coats
Prime and tack coats (where medium setting is acceptable)
Cold mix applications
Specifications
Viscosity (Saybolt Furol): ~20–100 seconds
Residue by distillation: Usually ≥ 60%
Float test: long duration, indicating “high float” performance
Penetration of residue: soft-to-medium hardness for flexibility
Standard Technical Properties of HFMS-1
| Property | Minimum (Min) | Maximum (Max) | Test Method & Notes |
|---|---|---|---|
| Viscosity (Saybolt Furol @ 25 °C) | 20 seconds | 100 seconds | ASTM D244 |
| Storage stability (24-h) | — | 1 % (separation/settling) | ASTM D6930 |
| Sieve test (solids content / aggregate size) | — | 0.10 % | ASTM D6933 |
| Particle charge | Negative / “Minus” (Anionic emulsion) | — | ASTM D6936 |
| Residue by distillation (bitumen content) | 55 % | — | ASTM D244 (or D6997) |
| Penetration of residue at 25 °C (100 g, 5 s) | 100 dmm | 200 dmm | ASTM D5 |
| Ductility of residue (at 25 °C, 5 cm/min) | 40 cm | — | ASTM D113 |
| Solubility of residue in trichloroethylene (TCE) | 97.5 % | — | ASTM D2042 |
| Float of residue @ 60 °C | 1200 seconds (or more) | — | ASTM D139 |
Additional Notes And Conditions
HFMS-1 is usually an anionic, medium-setting, high-float emulsion.
The high-float characteristic ensures the bitumen forms a thicker, resilient film on aggregates useful for surface treatments, chip seals, tack coats, cold-mix asphalt, base stabilization, and maintenance.
Storage and handling: typically supplied in steel drums, tankers, and must be kept properly agitated before application to avoid settlement.
