Stansteel Hotmix Parts & Service, Louisville, Kentucky, offers the Automatic AC Calibration System, which keeps plant personnel from having to pump hot liquid asphalt cement (AC) into a tanker and take it to a truck scale for weighing to determine calibration.
With this system, using the proper piping and valving, the liquid AC can be diverted from the run line on the plant directly to the AC calibration tank. The tank is loaded with a specific amount of material and then stopped with a weight registered on the electronic digitizer located in the control house. After the material is weighed, the process can be reversed and pumped back to the AC storage tank so that no waste occurs. The manufacturer states that the benefits of using the system include cost-effective tank management, a high return on investment when grade bumping, increased storage times and more.
