    means for conducting the asphalt paving material from the receiving means to the trench as the primary structure moves;

    the conducting means comprising a pair of side walls extending rearwardly along the paved surface and converging toward remote ends thereof to urge the paving material laterally toward the trench, and a rearwardly sloping upper surface portion spanning the two side walls to define an open bottomed flow chamber which terminates in a rear opening above the level of the paved surface, such that paving material is forced through the opening as the primary structure moves; and

    means for vibrating the primary structure as the paving material is conducted to the trench.
