Fiber Dosing Units are systems used to add fiber into the asphalt mix. These fully automatic dosing systems meet the cellulose fiber requirements needed for the wearing course and SMA (Stone Mastic Asphalt). They can be integrated into any asphalt plant and customized. With cellulose fiber additives, the physical properties of asphalt are improved—enhancing durability, flexibility, and longevity—resulting in stronger and more resilient road surfaces with reduced cracking risk.
