The challenge was first and foremost to meet the deadlines
The challenge was first and foremost to meet the deadlines, but also to cope with the different kinds of terrain encountered. For backfilling the construction, rebuilding the carriageway and installing the bottom layer, then the base course (2x12cm thick) and finally the wear course (6cm thick), the workers were able to rely on three machines equipped with the ASPHALT MANAGER 2 smart compaction system for automatic control of the compaction and progressive regulation of the amplitude. With their combination of power and gentleness, according to the types of layers and bases (old carriageways, backfill, the concrete structure over the tunnel), these machines ensured the success of this extremely demanding worksite.
