VÖGELE screeds are unique

VÖGELE’s High Compaction Technology (HCT) enables outstanding compaction performance directly behind the screed - achieving densities of up to 98%, eliminating the need for additional rolling in many applications.

At the core of this system are the pressure bars driven by pulsed-flow hydraulics, 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.

The single-tube telescoping system enhances flexibility on site, allowing millimetre-accurate screed width adjustment - ideal for projects with varying pave widths or complex geometries.

VÖGELE’s approach integrates mechanical precision with hydraulic performance to optimise density, stability, and surface finish right from the paver.

High compaction technology

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 ErgPlus5 screed consoles. This allows high compaction screeds to be used for standard tasks as well.

Hydraulic tamper stroke adjustment at the touch of a button on the Dash 5 Screed

A correctly set tamper stroke is a key factor in both compaction result and the floating behaviour of screeds.

It is very time-consuming to adjust the tamper stroke mechanically because the eccentric bolts on every bearing have to be adjusted manually. VÖGELE developed the hydraulic tamper stroke adjustment system for all compaction variants to stop this happening. The Dual Power Shift Tamper enables paver operators to set the ideal tamper stroke for the paving task in question quite simply at the touch of a button.

Simple and time-saving

The technology behind hydraulic tamper stroke adjustment is perfectly simple: altering the direction of rotation of the eccentric tamper shaft adjusts tamper stroke. Depending on configuration, this is either 2 and 4 mm or 4 and 8 mm. High-quality paving results can consequently be achieved much more conveniently, and an enormous amount of time saved compared to mechanical adjustment.

As an example: for a pave width of 12 m, 16 eccentric bolts need to be adjusted. Assuming 8 to 10 minutes per bearing, this means the whole process takes over 2 hours. The consequence is that the tamper stroke is often not adjusted at all if mechanical adjustment is required.
