Warm Mix Additives | Arkema Specialty Surfactants

For pavements to last, they must be constructed appropriately. Achieving the required density has often been considered the most critical factor affecting the ultimate performance of any pavement. Even the best asphalt mixes are guaranteed to succeed prematurely with proper asphalt compaction. Mat temperature plays a crucial role in the time allowed to achieve proper mat density.

What are Warm Mix Additives?

Warm mix additives are technologies used to reduce asphalt production and compaction temperatures while maintaining or improving warm mix asphalt performance. By modifying binder properties or improving coating and workability, these additives enable more efficient mixing, hauling, and compaction.

The Benefits of Warm Mix Additives

Warm mix additives provide a range of operational, environmental, and performance advantages for asphalt producers and paving contractors.

Lower Production and Compaction Temperatures

Warm mix additives allow asphalt to be produced and compacted at lower temperatures compared to traditional hot mix asphalt. This reduces thermal stress on materials and improves handling, especially in cooler conditions.

Improved Workability and Compaction

Enhanced coating and reduced binder viscosity improve mix workability, making it easier to achieve target density. This supports better compaction, longer haul distances, and increased flexibility during paving operations.

Reduced Emissions and Energy Consumption

Lower production temperatures reduce fuel consumption and greenhouse gas emissions at the plant. Warm mix technologies also improve jobsite conditions by minimizing smoke and odors.

Applications in Asphalt Production and Paving

Warm mix additives are used across a wide range of paving and asphalt production applications, helping improve performance, efficiency, and sustainability.

Road construction and resurfacing
High RAP and recycled asphalt mixtures
Long haul and extended paving operations
Urban and environmentally sensitive job sites

These technologies are often used alongside asphalt additives, asphalt emulsifiers and advanced pavement technologies to support a complete pavement performance strategy.

Arkema’s Warm Mix Additive Solutions

Arkema’s WarmGrip^®, and Cecabase^® RT warm mix asphalt technologies provide paving contractors with a compaction aid combined with industry-leading adhesion promotion and anti-stripping performance. These Road Science^® solutions are specifically formulated to enable asphalt production and compaction at lower temperatures while maintaining workability and extending pavement life through improved moisture resistance.
