This asphalt plant model was 7 feet tall, made out of sheet metal, with working parts. This model simulated the movements of an asphalt plant. Doors and chutes that operate in a real plant with hydraulic cylinders were mimicked using 12V electric linear actuators. Augers and buckets in a real plant that run on gear motors were simulated using miniature gear motors.
