Material Load-Out

After Hot Mix Asphalt (HMA) has been produced it is either stored for sale at a later time or immediately "surged" through bins into waiting trucks. Weight of HMA truck loads is determined by either low profile truck scales or through load cells on the surge bins themselves. Astec’s pioneering efforts in HMA storage silo technology changed the way producers operate. As the first true storage system, these silos brought the economies of long production runs to the HMA industry.
