Asphalt Warm Mix Additives
Improved compactibility at the lowest cost in use
Anova® non-toxic, liquid warm mix additive is designed to significantly improve the quality and reliability of asphalt pavement compaction at an efficient dosage.
Benefits of Using Cargill Anova® Warm Mix Additive
Made from bio-based chemistries, our warm mix additives provide economic value through lower plant costs due to reduced fuel consumption at lower production temperatures.
With Cargill’s Anova® warm mix additive, crews can reliably achieve density and improve workability at lower temperatures while reducing emissions and odor.

Frequently Asked Questions
How can I implement Anova® warm mix additive in my asphalt mix?
The Anova® warm mix additive can either be pre-blended into the binder at a terminal or other primary source of bitumen, or injected into the bitumen at the asphalt plant. At the plant injection is carried out with additive pumps. For drum plants the point of injection is usually inline into the bitumen pipe prior to reaching the drum. In a batch plant it is recommended the additive is injected into the binder weight pot in a manner that allows some comixing with the bitumen. The needs of every facility may be unique. Please contact your local Cargill representative to access consultation on best implementation practices for your specific needs.
Do I need to change my quality control, laydown, and compaction process when using WMA?
General best practices for handling, storage, laydown and compaction of Hot Mix Asphalt will generally also apply for Warm Mix Asphalt. As with any new mix, it is recommended that the paving crew monitor and adjust rolling patters and frequency as needed to optimally achieve target densities. Local specifications should be consulted, as modification to lab aging and other protocols may be required when production temperatures are reduced.
How do warm mix additives Contribute to reducing Green House Gas emissions?
The Anova® warm mix can help reduce the asphalt plant's energy needs and fuel consumption through reducing production temperatures, this in turn can lead to an overall decrease in GHG contribution.
Does the Anova® warm mix additive change the grade properties of bitumen or Polymer-modified asphalt?
When used at the recommended dosages, the Anova® warm mix additive will typically not result in a change in bitumen standard grade for either unmodified or modified binders.
