The pressure bars driven by pulsed-flow hydraulics are the core of VÖGELE high-compaction technology. By combining screed versions TP1, TP2 and TP2 Plus with this unique technology, our pavers achieve maximum compaction values. Compaction performances of up to 98% can be achieved with VÖGELE’s unique high-compaction technology – without rolling.
P is for pressure bars: the pulsed-flow hydraulics power pack
VÖGELE high-compaction technology starts with the pulse generator. It generates high-frequency pressure pulses. These keep the pressure bars in permanent contact with the pavement and force down the mix until it cannot be compacted any more. The reason: The pressure bars are located in the rear area of VÖGELE high-compaction screeds. This location enables pavers to achieve the highest possible compaction performance, as the mix is prevented from escaping either to the front or to the sides.
It is possible to switch easily from high compaction to conventional compaction and vice versa from the paver operator’s ErgoPlus 3 consoles. This allows high compaction screeds to be used for standard tasks as well.
