What Are Amine-Based Antistripping Agents?
Amine-based antistripping agents are high-performance chemical additives derived from fatty amines or polyamines. They are widely used in asphalt technology to improve the adhesion between bitumen and mineral aggregates, especially in acidic aggregate environments like granite or basalt.
These agents work by chemically bonding with the polar surfaces of aggregates and the non-polar bitumen, creating a stable interface that resists moisture intrusion. This prevents stripping—a common cause of pavement failures such as potholes and raveling.
Opal Paints Products Pvt. Ltd. manufactures premium amine-based antistripping agents designed for hot mix and warm mix asphalt applications. Our formulations ensure consistent coating, enhanced durability, and long-term moisture resistance even under extreme weather and traffic conditions.
Moisture infiltrates asphalt layers and weakens the bond between bitumen and aggregate. This leads to a phenomenon called 'stripping,' where the asphalt binder loses adhesion—causing potholes, raveling, and structural failure. Without proper adhesion, roads deteriorate faster under traffic and weather stress.
Amine-based antistripping agents chemically bond with both bitumen and aggregate surfaces, creating a strong and water-resistant interface. These additives improve adhesion, prevent stripping, and enhance the overall durability of asphalt mixtures—especially with acidic aggregates like granite. They help extend pavement life and reduce maintenance costs.
Benefits of Amine-Based Antistripping Agents
Explore how amine-based additives improve asphalt performance, resist moisture damage, and extend pavement life — especially in challenging aggregate conditions.
Improved Bitumen-Aggregate Bond
Amine-based antistripping agents form strong chemical bonds between bitumen and aggregates, preventing debonding caused by moisture infiltration.
Moisture Damage Resistance
These agents significantly increase water resistance in asphalt mixes, reducing stripping, potholes, and surface deterioration over time.
Proven Performance on Acidic Aggregates
Highly effective with acidic aggregates like granite and quartzite, where adhesion challenges are common in traditional mixes.
Increased Pavement Durability
By improving adhesion, amine-based agents boost the structural integrity of the asphalt, leading to longer-lasting roads under traffic stress.
Compatible with HMA & WMA
These additives integrate easily into both Hot Mix Asphalt (HMA) and Warm Mix Asphalt (WMA) production processes without changing workflows.
Compliant with IS 14982:2001
Opal Paints’ amine-based antistripping agents are tested and approved by CRRI and meet Indian and international quality standards.
