Following in-depth development work, Joseph Vögele AG launched the “hot-on-hot” paving method in 2007, registering the name “InLine Pave” as a trademark. An InLine Pave train from Vögele comprises three machines. First comes the feeder MT 1000-1 IP, which is supplied with paving mix from a delivery truck.
The feeder delivers paving mix for the binder course and surface course layers alternately via an extra long, heated charging conveyor. Perfect site logistics organized to the minutest detail is the key factor to make sure that the right material reaches the right paving site.
The binder course paver, a Super 2100-2 IP from Vögele, is the heart of the InLine Pave train. The modified standard paver is fitted with a special feeder module and charging conveyor to pass the paving mix for the surface course layer on to the surface course paver following immediately behind.
Yet another prerequisite is the high-compaction technology developed by Vögele, which is based on the concept of pulsed-flow hydraulics in the AB 600 IP screed with two pressure bars. The 10 cm thick binder course is pre-compacted to high density, enabling the surface course paver following right behind the Super 2100-2 to travel on the binder course without sinking into the freshly paved layer.
The third machine in the InLine Pave train, a Super 1600-2 or Super 1800-2 from Vögele, lays the 2 cm thick surface course on top of the still hot binder course layer.
Final compaction is effected by heavy rollers right behind the surface course paver. Gradual compaction of the binder and surface course layers by the successive use of light and heavy compaction equipment is not required, which considerably reduces the risk of jeopardizing the surface evenness achieved by the surface course paver.
