An aggregate-spreading device is disclosed for widening roads, filling trenches, spreading any kind of road construction material, and creating shoulders on the side of roads at a controllable, quick, and steady pace. The aggregate-spreading device may be controlled by electronic motors and electronic actuators. The aggregate-spreading device is equipped with a skeletal frame, either a first and a second adjustable spreader assembly attached on opposing ends of the skeletal frame, or a single spreader assembly for allowing an operator precise control over placement of an aggregate. The aggregate may be supplied to the first or second adjustable spreader assemblies by adjusting the rotation of a reversible conveyor system. The skeletal frame simplifies manufacturing of the aggregate-spreading device and allows for easy repairs and maintenance. The electronic motors and electronic actuators eliminate the need for hydraulics, allowing an operator to control the device from a remote location with a controller. |
