This invention is an aggregate extruder for the deposition of a multi-layered aggregate bed having layers of differing aggregate material. The extruder is divided into three sections transversely disposed over a defined surface, each of the sections contains a different aggregate material. A front grading baffle is mounted behind a front panel extending intermediate side panels forming the front dispensing section. A second grading baffle is mounted between the first and rear grading baffles forming the middle dispensing section, behind the front dispensing section, and a rear dispensing section. The extruder is self-propelled by a hydraulically operated ram mounted to each side panel. A panel is mounted to the rear of each side panel of the hopper and extends rearward thereof to define channel within which aggregate is maintained as the hopper moves along the surface. When the ram is activated it extends rearward for engagement with a form, and pushes the extruder along the defined surface. The aggregate material from each dispensing section is deposited on the ground. Each grading baffle grades the layer of aggregate deposited immediately forward the grading baffle to a preselected level.
