Abstract
A system to prevent accidental discharge of hot-mix asphalt at asphalt plants with multiple silos includes a closed circuit TV camera and a system of flashing lights. The TV camera has a fixed view of the loading area with a monitor at the control panel. When hot-mix asphalt is to be discharged into a truck, a switch is activated which causes a light beneath the bin to flash. This identifies the bin selected to open. The TV monitor is viewed and the position of the truck can now be visually confirmed along with the flashing light on the bin that has been activated. A second button must be pushed in order to complete the discharge of the hot-mix asphalt from the bin. Ideally, the second button is located either on the monitor or as close to it as possible in order to force the viewing of the screen before activating the second switch.
