ABSTRACT:
A material spreader system includes an elevated bridge for spanning a section of plastic concrete. A spreader including a hopper having an elongated rectangular slot is translated back and forth across the bridge to dispense a widthwise stream of topping material onto the underlying surface. Vibration generating elements are coupled at spaced apart intervals to the spreader hopper to provide for a uniform flow of topping material to the slot. A flow control device spans the length of the slot to dispense a continuous stream of topping material from the slot. A rotating metering device meters the flow of topping material through the slot. A motor translates the spreader back and forth across the bridge and rotates the rotating metering device as the spreader moves such that sequential translations of the spreader across the bridge followed by sequential translations of the bridge along the length of the plastic surface covers the entire surface with a uniform blanket of topping material.
