An improved device for simultaneously unrolling geotextile fabric and dispensing an aggregate layer for road construction comprises a hanger bar coupled to a vehicle frame. The hanger bar supports a roller bar adapted to carry a fabric roll. A dragger couples the hanger bar and arranges to present a dead-weight member on top of the fabric. An improved method using the improved device drags the chain on top of the fabric as it unrolls, thus holding the fabric in place. At the same time, a conveyered aggregate delivery system dispenses gravel on top of the fabric.
