A modified chip spreader is adapted to be used in a chip sealing train including a chip supply dump truck and an asphalt composition supply truck. The modified chip spreader is a self-propelled vehicle that has a receiving hopper on its front end for receiving stone chips from the chip supply dump truck, a spreader assembly on its rear end and a conveyor assembly for conveying the stone chips from the receiving hopper to the spreader assembly. The modified chip spreader also includes a spray assembly that is in fluid communication with an outlet line from the asphalt composition supply truck, which spray assembly is adapted to dispense an asphalt composition onto the surface of a roadway in front of the spreader assembly. The spreader assembly dispenses the stone chips onto the newly applied asphalt composition on the surface of the roadway.
