Abstract: An aggregate spreader for spreading a layer of loose aggregate onto a road surface includes a first hopper for receiving the loose aggregate, a plurality of gates or other suitable means associated with the first hopper for dispensing the loose aggregate onto the road surface, a plurality of sensors or other suitable means for sensing characteristics of the road surface, and an electronic controller or other means responsive to the sensors or sensing means and operably associated with the gates or dispensing means for controlling the placement of the layer of loose aggregate onto the road surface. In the preferred embodiment, each of the gates is independently controllable by an associated actuator, and the electronic controller is in electronic communication with the sensing means and in electronic communication with the plurality of actuators for controlling the placement of the layer of loose aggregate onto the road surface by independently controlling each gate of the plurality of gates.
