Asphalt Tack Coat and Bond Coat Bitumen Emulsifiers
What are Tack Coat and Bond Coat Emulsions?
A tack coat, also known as a bond coat, is an asphalt emulsion sprayed between existing and new pavement layers to create a strong adhesive bond. When pavement layers are properly bonded, they act as a single structural system that distributes traffic loads more effectively, improving pavement durability and reducing the risk of premature failure.
Without adequate bonding, pavement layers move independently, leading to cracking, rutting, slippage, moisture infiltration, and other distresses that shorten pavement life.
How Tack Coat Emulsifiers Improve Pavement Performance
Stronger Pavement Bonding
High-performance tack coat emulsifiers improve adhesion between pavement layers, increasing structural integrity and helping pavements better withstand repeated traffic loading.
Reduced Tack Coat Tracking
Traditional tack coats can be picked up by construction equipment before they fully cure, reducing bond strength and creating safety concerns. Arkema's emulsifier technologies are designed to minimize tack coat tracking while maintaining excellent adhesion.
Faster Construction and Traffic Return
By providing controlled curing and excellent emulsion stability, these technologies help contractors pave more efficiently while reducing project delays and allowing roads to reopen sooner.
Benefits of Tack Coat and Bond Coat Emulsifiers
- Faster paving with reduced tack coat drying time
- Superior bonding between pavement layers
- Reduced tack coat tracking by construction vehicles
- Improved pavement strength and durability
- Increased resistance to cracking and slippage
- Stable emulsion production and storage
- Lower roadway maintenance costs
- Reduced safety risks associated with tracked tack
Arkema's Tack Coat Emulsifier Solutions
The Road Science® emulsifiers, ArrMuls®, Stabiram®, and Dinoram® are specifically engineered to produce high-performance tack coat and bond coat emulsions for modern pavement construction.
Unlike many conventional non-tracking tack coats that rely on hard, brittle asphalt, Arkema's emulsifier technologies are designed to work with softer paving-grade asphalt binders, providing greater flexibility, improved strain tolerance, and enhanced resistance to cracking.
These emulsifiers can be formulated to meet industry specifications, including AASHTO M140 and ASTM D977 for slow-setting (SS-1h) emulsions. They also produce dilute and non-dilute emulsions that remain stable during extended storage and repeated pumping cycles, improving manufacturing efficiency and field performance.
Backed by Arkema's laboratory capabilities and field technical expertise, these technologies help customers produce stable emulsions that improve constructability, increase pavement durability, and reduce lifecycle costs.
