Bitumen SS-1: Reliable Slow Setting Emulsion for Pavement Preservation
What is Bitumen SS-1
Bitumen SS-1 (Slow Setting-1) is a cationic bitumen emulsion designed for applications where longer mixing and curing times are required. The “SS” stands for “Slow Setting,” while “1” denotes its viscosity classification. Because SS-1 emulsions remain stable for longer before breaking, they are ideal for fine aggregate mixes, slurry seal, tack coating, and soil stabilization projects.
Unlike cutback bitumen, which relies on volatile solvents, Bitumen SS-1 is water-based and more environmentally friendly. It is applied cold, making it safer to handle, easier to transport, and more cost-effective for contractors and distributors.
Why Choose Bitumen SS-1
Extended Working Time
SS-1 emulsions give crews more time for placement and mixing, ensuring uniform coating of fines and aggregates.
Cold Application
Eliminates the need for high heating, reducing fuel consumption and workplace risks.
Cationic Bonding
The positive charge in SS-1 allows strong adhesion to aggregates, even when surfaces are slightly damp or dusty.
Versatility
SS-1 is widely used in slurry seal, fog seal, tack coats, and soil stabilization.
Compliance and Availability
Manufactured to ASTM D2397 and AASHTO M140 standards, Bitumen SS-1 is recognized globally and supplied in drums, IBC tanks, or bulk tankers.
Applications of Bitumen SS-1
Slurry Seal and Micro-Surfacing
The slow-setting nature of SS-1 allows fines and mineral fillers to be fully mixed before curing, resulting in durable surface treatments.
Tack Coats
SS-1 is used to bond old and new asphalt layers together, ensuring long-lasting pavement performance.
Fog Seal Treatments
When diluted, SS-1 rejuvenates aged pavements, sealing micro-cracks and improving surface durability.
Soil and Base Stabilization
SS-1 can be mixed with soils and aggregates to strengthen base layers and reduce dust in unpaved areas.
Business Value in the B2B Market
For importers, distributors, and contractors, Bitumen SS-1 is a strategic product because:
It meets global demand for sustainable, cold-applied emulsions.
It is required in many municipal and highway maintenance specifications.
It ships safely in standard packaging, reducing logistical complexity.
It helps suppliers diversify their emulsion product range alongside CRS, CMS, and CSS grades.
This makes SS-1 a reliable and profitable choice in international bitumen trade.
Storage , Handling Recommendations
Store in a cool, shaded, and ventilated place.
Do not allow freezing, as this may break the emulsion.
Mix gently before use to restore uniformity.
Always use protective equipment during handling.
Frequently Asked Questions (FAQ)
Q1: What does SS-1 mean?
A: SS stands for Slow Setting, and “1” refers to its viscosity classification. It indicates that the emulsion remains workable longer before breaking.
Q2: What is the difference between SS-1 and CRS?
A: SS-1 sets slowly, allowing for better mixing with fines, while CRS (Rapid Setting) breaks almost immediately on aggregate contact.
Q3: Can SS-1 be diluted?
A: Yes, SS-1 is often diluted with clean water for fog seal or tack coat applications, as per project specifications.
Q4: Is SS-1 environmentally safe?
A: Yes, it is water-based and safer than cutback bitumen, though it must be stored and handled properly.
Q5: How is Bitumen SS-1 packaged for export?
A: It is supplied in 200 kg steel drums, 1,000 L IBC tanks, or bulk shipments depending on order size.
