Abstract: A dual-hopper aggregate spreader for spreading a layer of loose aggregate onto a road surface usually consists of a receiving hopper for the loose aggregate, and two (dual) second dispensing hoppers. In the preferred embodiment the conveyance of the dispensing hoppers is facilitated, in conjunction with other mechanical apparatuses, by a minimum of two conveyance glides, instead of rollers, gears, sprockets, etc., attached to a stationary frame that carries and aids in the conveyance of the dual dispensing hoppers, a minimum of two conveyance glides attached to the dual dispensing hoppers that then come into direct contact with the aforementioned frame glides, and, lastly, a minimum of two —one per side—tracking glides attached to the dual dispensing hopper's sides immediately adjacent and perpendicular to the conveyance glides.
