In a method of and an apparatus for improving the quality of an asphalt pavement, the asphalt is charged in a supply arrangement (2) adapted to be fitted in an inlet space (11) of a road finishing machine (1). The supply arrangement comprises a rotary vessel (3) in the shape of a truncated cone with a top inlet (30) and a smaller bottom outlet (31). The rotary vessel (3) has internal irregularities (32) for homogenizing the asphalt as to particle size and temperature. Preferably a distributing device (9) including at least one dividing member (93) and a rearrangement device (95) is also used, having the at least one dividing member (93) extending transversely over the belt conveyor (12) under the bottom outlet (31) to divide the flow of asphalt into layers, on top of one another, and the rearrangement device (95) to optimize form and feeding.
