Hot Mix Asphalt Pavement (HMA) and Warm Mix Asphalt Pavement (WMA) with improved stability

Our Modifiers are especially developed for dosage direct into the pug mill of a Hot Mix Asphalt plant. With more flexibility, less cost and a portfolio of high optimized effective modification you can engineer HMA with exact the properties you need.

Hot mix asphalt is a mixture of aggregates like gravel and sand and bitumen that requires heating before installation. Hot mixed asphalt is heated to a temperature of approx. 170-180°C in the production factory before it is loaded and laid on the construction site. Warm mix asphalt is applied at a temperature of around 30 - 40°C lower than an HMA. The warm mixed asphalt is only heated to a temperature of approximately 130-150°C. Both are most useful for large-scale paving applications. The advantages are the durability and the flexibility and malleability, that allow it to shrink and expand during different temperatures without cracking or becoming damaged.
