HINCOL HINTAC Emulsion
Trackless Tack Coat | Polymer Modified | PremiumHINCOL HINTAC is a high-performance Polymer Modified Cationic Bitumen Emulsion engineered specifically for Trackless Tack Coat applications on high-traffic roads, national highways, expressways, urban corridors, and airport infrastructure. Unlike conventional tack coats, HINTAC does not get picked up (tracked) by vehicle tyres or construction equipment after application — ensuring the tack coat layer remains intact and delivers maximum interlayer bond strength at all times.
As part of HINCOL’s premium range of bitumen emulsions, HINTAC is backed by the global polymer modified emulsion technology of parent organization COLAS SA, France — pioneers of bitumen emulsion technology since 1929. The polymer modification gives HINTAC significantly higher cohesive strength after breaking, preventing displacement under construction traffic loads while maintaining full adhesion to the existing pavement surface.

Where HINCOL HINTAC is Used
HINTAC is the preferred tack coat for projects where construction traffic passes over the emulsion before overlay, and where maximum interlayer bond strength is required.
National Highways
High-traffic NH overlay and resurfacing projects with tight traffic windows
Expressways
High-speed expressway pavement works where bond strength is critical
Urban Roads
City flyovers, underpasses, and urban corridors with constant traffic
Airport Runways
Airfield pavement resurfacing where zero contamination is essential
Bridges & Flyovers
Bridge deck overlays and flyover resurfacing with heavy construction traffic
Mill & Fill Projects
After milling operations, before new asphalt overlay on milled surfaces
How HINTAC Trackless Tack Coat Works — Step by Step
1
Surface Preparation
Existing pavement surface is swept and air-blown clean — free from dust, loose material, milling debris, and standing water before HINTAC application.
2
Uniform Spraying
HINTAC is sprayed uniformly using a calibrated bitumen distributor at the rate specified for the surface condition and project specification.
3
Rapid Breaking
The polymer modified emulsion breaks rapidly on contact with the surface, forming a thin, cohesive bitumen film that sets firmly — remaining in place even under construction traffic.
4
Trackless State
Unlike conventional RS1 tack coats, HINTAC’s polymer-enhanced film does not get picked up by paver tyres or roller wheels — the tack coat layer remains fully intact.
5
Overlay Placement
New asphalt layer (DBM, SDBC, or BC) is placed over the fully set HINTAC tack coat — achieving maximum interlayer bond strength and long-term pavement durability.
Key Advantages of HINCOL HINTAC
✅ Trackless — No Tyre Pick-Up
Construction equipment and paving trains pass over without picking up the emulsion — full tack coat coverage is preserved until overlay.
✅ Superior Bond Strength
Polymer modification provides significantly stronger interlayer adhesion than conventional RS1, resisting layer slippage under heavy traffic loads.
✅ Prevents Surface Contamination
Since HINTAC doesn’t track, there is no bitumen contamination of the overlay material from tyre pick-up — maintaining mix quality.
✅ Faster Construction
Rapid setting nature allows paving operations to proceed quickly after tack coat application — minimising road closure time.
✅ No Heating Required
Cold application at ambient temperature — eliminates heating equipment, improves site safety, and reduces project cost.
✅ Reduces Pavement Failure Risk
Strong interlayer bond prevents delamination, rutting, and structural failure — extending pavement service life significantly.
✅ COLAS Technology
Formulated using polymer emulsion expertise from COLAS SA, France — global leaders in road construction technology since 1929.
✅ ISO 9001:2015 Quality
Manufactured under certified quality management processes at HINCOL’s plants across India, with NABL-accredited lab testing.

Success Story: HINTAC on High-Traffic Urban Highway Overlay
Urban Highway Resurfacing — High Construction Traffic Corridor
Zero Tracking ObservedChallenge: An 8-lane urban highway resurfacing project where paving equipment, dump trucks, and rollers were required to cross the tack coat repeatedly before overlay placement. Conventional RS1 tack coat was being picked up by tyres — compromising bond between layers and causing rework.
Solution: HINCOL HINTAC provided complete trackless performance. Despite repeated passes by heavy construction equipment, the tack coat remained fully intact — delivering maximum interlayer bond with zero contamination of the overlay mix.

Frequently Asked Questions
What is HINCOL HINTAC used for?
HINCOL HINTAC is a Polymer Modified Cationic Bitumen Emulsion used as a Trackless Tack Coat on high-traffic highways, expressways, urban roads, flyovers, and airport runways. It bonds new asphalt overlays to existing pavement layers while ensuring that construction vehicles and paving equipment do not pick up the emulsion — preserving full interlayer bond strength.
What is a trackless tack coat and why is it needed?
A trackless tack coat is a polymer modified bitumen emulsion that sets with high cohesive strength, so vehicle tyres and construction equipment do not pick it up (track it) after application. On busy highways and high-traffic construction sites, conventional tack coats like RS1 can be displaced by construction traffic before overlay placement — removing bond from critical areas. HINTAC eliminates this problem entirely, ensuring complete tack coat coverage is maintained until the asphalt overlay is placed.
What is the difference between HINTAC and RS1 tack coat?
- RS1: Standard Rapid Setting Cationic emulsion — cost-effective tack coat for general road work. Can be tracked by tyres if construction traffic crosses before overlay.
- HINTAC: Polymer Modified Rapid Setting emulsion — premium trackless tack coat. Polymer modification gives significantly higher cohesive strength after breaking. Zero tyre pick-up. Preferred for high-traffic highways, expressways, mill & fill operations, and airport pavements.
Where should HINTAC be used instead of RS1?
HINTAC should be specified instead of RS1 when:
- Construction equipment, dump trucks, or paving trains must cross the tack coat before overlay
- The project is on a National Highway, Expressway, or high-traffic urban road
- The surface being overlaid is milled asphalt (higher contamination risk)
- Airport pavement works are involved (zero contamination tolerance)
- High ambient temperatures are expected (which reduce viscosity of conventional tack coats)
Does HINTAC require heating before application?
No. HINTAC is a water-based bitumen emulsion applied at ambient temperature — no heating equipment required. This makes it safe, fast, and significantly more cost-efficient than hot-applied tack coat methods.
What surfaces can HINTAC be applied on?
HINTAC can be applied on bituminous surfaces (existing asphalt pavement), milled asphalt surfaces (after cold planing), aged bituminous surfaces, and concrete pavement — wherever an asphalt overlay is to be placed and maximum interlayer bond strength is required.
How is HINTAC applied?
- Surface must be clean, dry, and free from dust and loose material
- Spray uniformly using a calibrated bitumen distributor
- Allow to break (rapid setting) before overlay placement
- Overlay with asphalt (DBM, SDBC, or BC) once tack coat has set
Is HINCOL HINTAC compliant with IS 8887?
Yes. HINCOL HINTAC is manufactured under IS 8887 specification for polymer modified cationic bitumen emulsion, under ISO 9001:2015 certified quality management processes at HINCOL’s plants across India.
What is the difference between a tack coat and a bond coat?
- Tack Coat (RS1 / HINTAC): Light application between two bituminous layers to create adhesion. Applied between DBM and surface course (SDBC/BC).
- Bond Coat (HINCOL BONDCOAT C50BP): A heavier, more specialized polymer modified application for bridge decks and high-stress locations where extremely high shear resistance is required.
What other HINCOL products are used alongside HINTAC in road construction?
- Prime Coat (WMM to DBM): HINCOL EMULTRA PLUS SS1 IS or HINPRIME SS1 ASTM
- Standard Tack Coat: HINCOL Emulsion RS1 (for lower-traffic roads)
- ETB / Stabilization: HINCOL SS2-Stab
- Surface Dressing: HINCOL Chip Seal Emulsion RS2
