A system for metering reinforcing aramid fibers into an asphalt mixer includes a vertical feed chute with straight walls that spans substantially a full diameter and a full length of a horizontal feed auger to feed bulk fibrous material by gravity from the feed chute in a radial direction along the length of the feed auger. The feed auger is rotated at a controlled rate proportionally to the rate of production of an asphalt and mineral aggregate mixture. A pneumatic conveying line conveys the reinforcing fibers from an outlet end of the feed auger to an asphalt mixer for mixing with the asphalt and mineral aggregate to produce a fiber reinforced asphalt concrete with an accurately proportioned amount of fiber dispersed therein.
