InLine Pave breaks all records.

Single-lane rehabilitation on Germany’s A61 motorway using InLine Pave

The A61 motorway leads from Hockenheim, which is known for its Formula 1 racing circuit, all the way to the Dutch border. It crosses as many as three German States on the way – namely, Baden-Württemberg, Rhineland-Palatinate, and North Rhine-Westphalia – and is used by correspondingly high amounts of heavy traffic. The tremendous axle loads of heavy trucks had caused deep rutting on the right-hand lane.

As the right-hand lane was to be reconstructed to particularly high standards of quality, the road authority in charge decided in favour of Vögele’s hot-on-hot rehabilitation method using InLine Pave. The time schedule for completion of the rehabilitation measure was to be kept short, and the road was to remain open to traffic all the time, so that paving in hot application using Vögele’s InLine Pave method was found to be exceptionally suitable for the section of motorway between the Mutterstadt and Ludwigshafen junctions.

W 2000 cold milling machines from Wirtgen began by removing the damaged asphalt layers across the full lane width. Pavement rehabilitation on the right-hand traffic lane was carried out immediately afterwards by Vögele’s InLine Pave train, which consisted of a feeder type MT 1000-1 IP, binder course paver Super 2100 IP, and surface course paver Super 1800-1. Final compaction was effected in just a few roller passes by heavy-duty tandem rollers from Hamm.

The entire paving operation on the A61 was completed in record time. Just three days were needed to complete the “hot-on-hot” operation, paving the new binder and surface course layers on the right-hand lane across a width of 4.50 m and over a total length of 3 km. Had conventional methods been used, a minimum of five days would have been necessary for completion of the paving operation.
