Hot Mix Asphalt Additives for High-Performance Pavements
What are Hot Mix Asphalt Additives?
Hot mix asphalt additives are chemical solutions used to enhance the performance of asphalt mixtures produced at conventional temperatures. These additives improve adhesion, durability, and resistance to moisture damage, helping extend pavement life and maintain performance under traffic and environmental conditions.
The Role of Additives in Hot Mix Asphalt
Improving Adhesion and Moisture Resistance
Hot mix additives enhance the bond between bitumen and aggregates, helping prevent stripping and moisture-related damage that can reduce pavement durability.
Enhancing Durability and Pavement Performance
By improving mixture stability and resistance to environmental and traffic stresses, these additives support longer-lasting pavements with reduced maintenance needs.
Benefits of Hot Mix Asphalt Additives
Improved Adhesion Between Binder and Aggregates
Enhanced bonding helps ensure pavement integrity and reduces the risk of early failure.
Enhanced Resistance to Moisture Damage
Additives improve the mix’s ability to withstand water infiltration, reducing stripping and extending pavement life.
Increased Pavement Durability and Longevity
Improved performance under traffic and environmental conditions leads to longer service life and fewer repairs.
Applications in Asphalt Production and Paving
Hot mix asphalt additives are used across a wide range of paving applications, including:
- Road construction and resurfacing
- High traffic and heavy load pavements
- Polymer-modified asphalt systems
- High RAP and recycled asphalt mixtures
These technologies are often used alongside asphalt additives and advanced pavement technologies to support a complete pavement performance strategy.
Arkema’s Hot Mix Asphalt Additive Solutions
Arkema has been an industry innovator in hot mix asphalt additives, including adhesion promoters and anti-stripping additives, for several decades. Our solutions are designed to enhance pavement performance by improving adhesion between binder and aggregates and reducing moisture damage.
Arkema’s AD-here® and Cecabase® (EU) adhesion promoters are added in small amounts to hot mix asphalt and offer easy handling and flexible dosing options for both asphalt terminals and producers. These additives help ensure pavements meet design life expectations, reduce the need for repairs, minimize traffic disruptions, and improve overall safety and ride quality.
Arkema supports customers with technical expertise, laboratory testing, and on-site support to ensure optimal additive performance.
