Abstract of the Disclosure Disclosed is a method and apparatus for recycling asphalt concrete roadways by adding little or no new hot mix to the recycled surface. The apparatus includes means for heating the roadway and applying emulsified asphalt thereto prior to scarifying the heated surface. The surface is then scarified so as to loosen the heated asphalt. The scarified material is then treated with asphalt and, if desired, a rejuvenating agent. They are mixed thoroughly to form a hot mix of asphalt concrete from the old road material. The rejuvenated hot mix is leveled by means of screws and then compacted substantially by a vibrating screed. The screed has a continuous bottom plate and a plurality of relatively movable upper sections which are connected by turnbuckles adapted to be adjusted for bending the bottom plate of the screed to conform to the contour of the road crown. Final compaction of the road surface is obtained by rollers.
