ABSTRACT:
A truck frame for road repair work includes a tank containing heated asphalt, a repair materials hopper, a front discharge chute and a drive worm conveyor within the hopper for moving repair aggregate from the hopper to the chute for deposit in a pavement pothole or the like. The discharge end of the chute is manually moveable from side to side and front to back and carries an outlet for the heated asphalt to coat the aggregate emerging from the chute with the asphalt, for spreading the asphalt coated aggregate into the pavement defect being repaired. The chute has a first air inlet attached thereto remote from the discharge in and through which air under pressure is applied to the chute to cause a swirling motion of the aggregate as it descends through the chute toward the pavement, and a second air inlet at the opposite end from the outlet for receiving air under pressure to clean a pothole before the repair material is applied thereto.
