The Challenge

Why Anti-stripping Agents Matter

Asphalt pavement is constantly exposed to water infiltration through surface cracks, capillary action, and traffic pumping. Without proper adhesion between bitumen and aggregate, moisture strips the binder from the stone surface, leading to premature pavement failure.

💧

Moisture Damage

Water penetrates the asphalt through voids, capillary action, and vapor condensation. Once inside, it attacks the bitumen-aggregate interface and weakens adhesion, causing stripping from the bottom up.

⚠

Pavement Distress

Stripping leads to aggregate loss, raveling, potholes, and rutting. Road authorities face rising maintenance costs and shortened pavement service life, especially under heavy traffic and freeze-thaw cycles.

🔗

Chemical Bonding

COUNTERBINDER A-585 forms a surface-active molecular bridge: the hydrophilic amine head bonds to the aggregate surface, while the hydrophobic tail integrates into the bitumen phase, creating a durable, moisture-resistant interface.

✅

Certified Performance

Tested by accredited laboratories using KS F 2398 (TSR method). A-585 consistently exceeds the standard threshold, ensuring reliable long-term adhesion even under severe moisture exposure conditions.

Advantages

Why COUNTERBINDER A-585

Engineered as a direct replacement for legacy imported anti-stripping agents. Manufactured in Korea with consistent quality and reliable supply.

🔬

Low Viscosity, Easy Dosing

Liquid form with low viscosity enables accurate dosing and homogeneous mixing into hot bitumen at standard asphalt plant temperatures. No special equipment required.

🌡

High Boiling Point

Maintains thermal stability during hot storage and mixing. The active ingredient remains effective even after extended hot-mix production, unlike volatile alternatives that degrade at elevated temperatures.

💪

Dual Function

Acts as both adhesion promoter and corrosion inhibitor. Protects not only the bitumen-aggregate interface but also metal components in contact with bituminous mixtures.

📍

Domestic Production

Manufactured in Daejeon, Korea with full QC documentation (COA per lot). Eliminates import lead times and ensures stable, year-round supply for large-scale paving projects.

Mechanism

How COUNTERBINDER A-585 Works

The amine-based molecular structure creates a chemical bridge between the non-polar bitumen and the polar aggregate surface.

Dosing

A-585 is added to hot bitumen at 0.2~0.5% dosage before aggregate mixing

Adsorption

Amine head group adsorbs onto the polar aggregate surface, displacing water molecules

Integration

Hydrophobic tail integrates into the bitumen phase, forming a molecular bridge

Protection

Moisture-resistant interface resists water infiltration and prevents stripping over time

Applications

Where COUNTERBINDER A-585 Is Used

🛣

Highway Paving

High-traffic expressways and national roads requiring long-term moisture resistance and structural durability under heavy axle loads.

✈

Airport Runway

Runway and taxiway asphalt where moisture damage must be prevented under extreme loading and jet blast conditions.

🏙

Urban Roads

Municipal roads, bridges, and tunnels where water exposure is frequent and pavement maintenance is costly and disruptive.

🏞

Cold Climate Regions

Areas subject to freeze-thaw cycles where moisture infiltration and ice formation accelerate stripping and pavement deterioration.

🚢

Port & Industrial

Container terminals, logistics parks, and industrial yards with heavy vehicle loading and exposure to salt water or chemicals.

🔨

Asphalt Emulsion

Can also serve as an emulsifier component for asphalt emulsion production, providing additional formulation versatility.
