A device for dispersing and metering fibers which includes a frame, and a hopper mounted on the frame and having an inlet opening for receiving fibers therein. A screen is provided through which the fibers from the inlet opening must pass for separating any existing fiber clumps into a size not exceeding a size predetermined by the screen. A primary fluffing device is provided for creating a uniform dispersion of fibers within the hopper. An outlet opening is provided for allowing the fibers to exit the hopper. A controllable metering device is provided in the outlet opening for transporting a metered quantity of fibers out of the hopper through the outlet opening. A housing structure is connected to an outlet end of the metering device, the housing structure including an air inlet opening into the housing and a secondary fluffing device inside of the housing for further reducing in size any fiber clumps to separated discreet fibers. An air impeller device is provided for moving a large volume of air into the air inlet opening and through the housing to effectively entrain the discreet fibers in a moving air stream and moving the air with the fibers entrained therein to an outlet connected to an asphalt cement and fiber mixer.
