An improved moveable road repair and surfacing vehicle of the type having a frame, an aggregate material hopper mounted on a frame, a container on the vehicle for binder material such as asphalt, conveyor means associated with the hopper for carrying aggregate material, a discharge chute associated with the conveyor means for receiving aggregate material carried thereon and directing material downwardly, a discharge outlet on the chute for dispensing the aggregate material therefrom for deposit on a roadway surface, and means for spraying binder material on the dispensed aggregate material. The improved apparatus for applying asphalt coated aggregate to the roadway surface includes a hollow tube rotatably mounted within and extending below the outlet of the aggregate discharge chute, at least one projection mounted on the periphery of the hollow tube for premixing the aggregate material moving downwardly in the discharge chute, means attached to the hollow tube adjacent the bottom thereof for causing the aggregate material to swirl as it drops downwardly to the roadway surface for the discharge outlet, and means attached to the vehicle adjacent the discharge outlet for spraying binder material on the swirling aggregate material after it leaves the discharge outlet but before it reaches the roadway surface.
