An apparatus is disclosed for the cold, in-place recycling of asphalt paving of an asphalt roadway. The apparatus is self-propelled, and it includes a cylindrical milling drum mounted at a medial location along its longitudinal length and which serves to remove a thickness of the asphalt paving and break the same into particles as the apparatus moves forwardly along the roadway. The particles are lifted to a separating screen which is positioned forwardly of the drum, and the particles are thereby separated into a first portion of relatively small particles suitable for recycling and a second portion of oversized particles. The first portion is delivered to the rear end of the apparatus where it is mixed with a suitable liquid additive, and then discharged onto the roadway. A following paver then forms the discharged material into new paving. The second portion of oversized particles is discharged onto the roadway at a location in front of the milling drum. Thus the milling durm again contacts the second portion upon forward mavement of the apparatus, and the durm acts to further crush the particles and cause them to be recycled through the apparatus.
