1. A geotextile-roll applicator device for coupling to a vehicle frame, the device comprising:
- a support frame;
a roller bar supported by the support frame and adapted to receive a roll of geotextile fabric; and
a dead-weight member supported by the support frame and configured to extend over and weigh-down a portion of the geotextile fabric that is dispensed from the roll; and
wherein the support frame comprises;
a first and second receiver hitch coupled to the vehicle frame;
a first and second stinger member, each stinger member respectively comprisinga stinger arm having a first arm-end adapted to slideably insert into the respective receiver hitch, an oppositely disposed second arm-end including a connecting means, and holder leg disposed intermediate to the first and second arm ends at a holder-leg first end;
a hanger bar coupled to the first and second stinger members;
a dragger bar adapted to couple to the hanger bar, the dragger bar further comprising a plurality of attaching members; and
wherein the hanger bar further comprises;
a first winch means for selectively positioning the roller bar relative to the support frame.

Abstract
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.
