HINCOL Emulsion SS2-Stab (Bulk)

HINCOL Emulsion SS2-Stab is a Slow Setting Cationic Bitumen Emulsion specifically designed for Emulsion Treated Base (ETB) construction, soil stabilization, in-situ pavement recycling, and Full Depth Reclamation (FDR). It significantly increases the cohesive strength and moisture resistance of treated granular base materials — for both new road construction and pavement rehabilitation projects.

An Emulsion Treated Base (ETB) is a pavement base layer where granular material is treated with SS2-Stab bitumen emulsion. The bitumen disperses only among the finer particles of the mix — creating a bitumen-rich mortar between coarse particles that significantly increases cohesion and reduces moisture sensitivity. ETBs remain granular in character (unlike asphalt) and are designed per IRC 37: 2012/2018.

• SS2: For road surface maintenance — Fog Seal, Slurry Seal, Premix Seal Coat on existing bituminous pavements.
• SS2-Stab: For structural base improvement — ETB construction, soil stabilization, in-situ recycling, and FDR. Has additional residue properties (Penetration 60–120, Ductility min 50) suited for base layer structural work.

Full Depth Reclamation (FDR) is a rehabilitation technique where the entire existing pavement structure — asphalt surface, base, and subbase — is pulverized and mixed with HINCOL SS2-Stab in place. The treated ETB layer eliminates import of new aggregates, reduces project cost by 40–65% vs conventional reconstruction, minimizes traffic disruption, and creates a structurally superior recycled base.

• Crushed stone of all rock types
• Previously untreated natural gravels
• Reclaimed Asphalt (RA) material
• Reclaimed pavement layers (previously stabilized crushed stone/gravel)
• Marginal materials such as sands (with experienced design)
• WMM (Wet Mix Macadam) stabilization — with Portland cement and SS2-Stab

The residual bitumen emulsion added for ETB construction typically does not exceed 3% by mass of dry aggregate. Active filler (cement or hydrated lime) is often added at up to 1% by mass. The ratio of bitumen percentage to cement percentage must always be greater than 1 — if this ratio falls below 1, the material should be considered a cement treated material rather than ETB.

• Increased strength: ETB can replace higher-quality materials in upper pavement layers — significant cost savings.
• Improved durability: Bitumen encapsulates fine particles, improving moisture resistance.
• Lower quality aggregates can be used successfully.
• Not temperature sensitive — unlike hot mix asphalt, reduces temperature-related rutting risk.
• Environmental benefits: Conservation of natural aggregates, reduced haulage, lower emissions.
• Ease of rehabilitation: Primary failure mode is permanent deformation — far easier to fix than cracking.

ETB and cold mix asphalt are fundamentally different. In ETBs, the bitumen only disperses among the finer particles — coarser aggregate particles remain uncoated. This results in a granular material with improved cohesion, not a bitumen-coated mix. ETBs are not black, have no sticky feel, and are not prone to cracking under tensile stress. Cold mix asphalt has continuous bitumen coating on all aggregate sizes and behaves like asphalt.

Yes. HINCOL Emulsion SS2-Stab is manufactured conforming to IS 8887 specification for Slow Setting Cationic Bitumen Emulsion. Quality testing is conducted for every batch (sieve, viscosity, storage stability) and every 200 MT (particle charge, residue properties including penetration, ductility, and solubility) under ISO 9001:2015 certified processes.

• Short-term (3–5 days): Can be easily stored without special measures.
• Medium-term (up to 2 weeks): Gentle weekly agitation or drum rolling to maintain homogeneity.
• Maximum storage: Up to 3 weeks in cleaned tanks stored at 10°C–50°C.
• Never heat above 85°C, freeze, or over-circulate the emulsion.

• In-Situ Treatment: Using recyclers directly on the road for rehabilitation projects — minimizes haulage and traffic disruption.
• In-Plant Mixing: Material processed in a purpose-built mixing plant — better control of input materials and quality, suited for new construction with virgin aggregates.

ETB construction must be done at temperatures above 5°C. The recycled ETB layer remains granular in character and is processed using the same compaction equipment as unbound granular materials.
