In Hungary the existing main road network has asphalt pavements, but dense bitumen macadam pavements made with cut-back bitumen can be found in large quantities on the secondary road network. These macadam pavements are mostly covered with one layer of asphalt or surface dressing. The dense bitumen macadam pavements are characterized by post-compaction caused by traffic during the lifetime of the road. Because of the post-compaction the profile of the macadam pavements is uneven, affecting riding quality and bearing capacity. These pavements are not constructed nowadays in the Hungarian network, but the rehabilitation of these structures remains troublesome. For the rehabilitation of these pavements three different in situ recycling methods can be applied: recycled asphalt with binder spraying; remix technology with mixed recycled asphalt; or deep remix technology in situ. In case of each method, the bituminous binder is bitumen emulsion or foamed bitumen. The first two technologies are used for the rehabilitation of low trafficked roads, the third technology is applied to both low and heavy trafficked roads. The report summarises generally the three possible variations of technology, gives concrete examples of the applications, makes a comparison between the economics of the methods, mentions the Hungarian environmental operative regulations and logistical situations for milled/recycled asphalt.
