Foamed bitumen stabilisation
WebFoamed bitumen is produced from normal bitumen at a temperature of approx. 175°C using state-of-the-art technology. Inside WIRTGEN recyclers, microprocessor-controlled … WebFoamed asphalt stabilized base (FASB) combines combinations of reclaimed asphalt pavement (RAP), recycled concrete (RC), and/or graded aggregate base (GAB) with a foamed asphalt binder to produce a partially stabilized base material. The foamed asphalt content is usually too low to fully coat all of the aggregate particles, as is the case in hot
