ABSTRACT:
Apparatus and method for measuring out liquid asphalt gravimetrically. The apparatus comprises a plurality of tanks for containing liquid asphalt, each tank being suspended from a load cell, a series of pipes, valves and a pump for selectively filling the tanks with asphalt and a series of pipes, a valve and a variable rate pump for selectively removing the liquid asphalt from the tanks. The load cells are connected to a control circuit which converts the signals from the load cells into the corresponding weight of the tanks and the liquid asphalt contained therein. The control circuit is also connected to the variable rate pump to control the rate at which liquid asphalt is removed from the tank in response to the load cells.
