What is HINCOL Emulsion SS2 FDR?

HINCOL Emulsion SS2 FDR is a high-residue (60%+) slow setting cationic bitumen emulsion formulated specifically for cold in-place recycling of asphalt pavements. When injected into a cold recycler/reclaimer machine along with water (and optionally cement), it binds pulverised Reclaimed Asphalt Pavement (RAP) material into a new, structurally stable base course — all in a single pass, on-site, at ambient temperature.

SS2 FDR’s slow setting characteristic gives the recycler machine ample time to mix, place, shape, and compact the recycled material before the emulsion breaks and cures. The high residue content (60%+) means more bitumen binder per kg of emulsion — translating directly to better RAP coating and stronger recycled base.

Why Choose Full Depth Reclamation Over Mill & Fill?

Conventional pavement rehabilitation requires milling out the old layer, hauling it to a disposal site, trucking in new virgin aggregate and asphalt mix, and laying it hot. FDR eliminates all of that — and saves 25–40% in project cost.

Cold Recycling & FDR with HINCOL Emulsion

Watch how HINCOL’s emulsion-stabilised cold recycling transforms a distressed pavement into a new structural base in a single pass.

SS2 FDR Technical Specifications

SS2 FDR meets the requirements of IS 8887 for SS2 grade cationic emulsions with enhanced residue content for cold recycling applications. Every batch is tested in HINCOL’s NABL-accredited laboratory.

How the FDR Process Works with SS2 FDR

A single self-propelled cold recycler machine performs the entire FDR sequence in one pass — pulverising the old pavement, injecting emulsion and water, mixing, and depositing the recycled mix ready for grading and compaction.

Recommended SS2 FDR Application Rates

Exact emulsion dosage is determined by mix design trials. The values below are typical ranges for planning purposes.

SS2 FDR vs SS2-Stab — What’s the Difference?

Both are slow setting cationic emulsions, but they serve completely different applications. Choosing the right grade is critical to project success.

Advantages of HINCOL Emulsion SS2 FDR

• Single-Pass Construction — Pulverisation, mixing, placement happens in one pass with the cold recycler. No multi-stage logistics, no separate plants.
• 100% RAP Utilisation — Existing bituminous pavement is fully recycled in-place. Zero landfill, zero disposal cost.
• High Residue Content (60%+) — More bitumen binder per kg of emulsion means better RAP coating and stronger recycled base.
• No Heating Required — Applied at ambient temperature. No bitumen heaters, no fuel cost, no thermal safety hazards.
• Eliminates Reflective Cracking — Old pavement cracks are pulverised and homogenised — they cannot propagate to the new overlay.
• Stronger Stabilised Base — Bitumen emulsion creates a flexible, water-resistant stabilised base — superior to unbound granular base.
• Faster Project Completion — Single-pass operation typically achieves 0.8–1.5 km per day per recycler — 2× faster than Mill & Fill.
• Lower Carbon Footprint — No hot bituminous mix, no virgin aggregate hauling, no waste hauling — major CO₂ reduction.
• NHAI / MoRTH Recognised — Cold in-place recycling with bitumen emulsion is covered under MoRTH Specifications and has been used on NHAI projects.
• Full Project Support — HINCOL provides lab mix design, on-site technical support, and emulsion supply logistics tailored to FDR projects.

Storage and Handling Guidelines

• Storage Temperature: Maintain between 10°C and 50°C. Never freeze. Never heat above 85°C — overheating breaks the emulsion permanently.
• Storage Containers: Use clean, sealed bulk tanks or original 200 kg drums (MS or HDPE). Tank materials: mild steel or stainless steel (avoid copper, aluminium, galvanised surfaces).
• Agitation: Gentle weekly circulation or drum rolling is recommended for storage beyond 2 weeks. Avoid high-shear pumps that can destabilise the emulsion.
• Shelf Life: Approximately 3 months in sealed containers under recommended storage conditions.
• On-Site Handling: Connect emulsion tankers directly to the cold recycler’s emulsion supply system. Maintain consistent flow rate during pulverisation.
• Cross-Contamination: Never mix cationic SS2 FDR with anionic emulsions — coagulation will occur instantly. Use dedicated tanks and pipelines.
• Safety: Standard PPE — gloves, goggles, full-sleeve clothing. Wash spills with cold water before the emulsion breaks. Refer to HINCOL MSDS for full safety information.

Typical FDR Projects Using SS2 FDR

• National Highway Rehabilitation — NHAI projects where the existing bituminous pavement has reached structural failure and full-depth treatment is needed.
• State Highway Strengthening — PWD/State highway authority projects upgrading low-volume roads to higher traffic categories.
• Rural Road Reconstruction — PMGSY and rural road upgrade projects with limited budgets and remote locations (FDR’s low logistics footprint is ideal).
• Airport Taxiway Rehabilitation — Where minimising operational disruption is critical and FDR’s single-pass speed delivers project completion faster than Mill & Fill.
• Heavy Industrial Yard / Port Pavements — Where heavy axle loads have caused full-depth failure and a stiffer stabilised base is needed.
• Urban Arterial Roads — Where traffic disruption windows are short and FDR’s single-pass speed enables work within 24–48 hour closures.
