ABSTRACT:
An asphalt finishing screed is disclosed which is adapted to achieve essentially complete compaction of the asphalt mix over a range of finished mat thicknesses. The screed comprises a vertically adjustable strike off bar, a rotary compactor positioned immediately behind the bar, and a screed plate positioned immediately behind the rotary compactor. In one preferred embodiment, the rotary compactor comprises a rotor which includes a plurality of freely rotating rollers about the peripheral surface thereof. In operation, the adjustable strike off bar is set at an elevation so as to meter the material to the rotary compactor and to achieve the desired compaction for the particular thickness of the finished mat being laid. The rotary compactor then impacts the mat in an essentially vertical direction and so as to achieve complete compaction of the mix.
