The extending screed for all dash 3 pavers of the 2.5-m class

The AB 500 can be combined with all dash 3 pavers of the 2.5 m class. With its infinitely adjustable single-tube telescoping system, this screed covers a virtually unlimited spectrum of applications with paving widths ranging from 8 ft 4 in to 16 ft 5 in and even to 27 ft 10 in with bolt-on extensions. The AB 500 is available with tamper and vibrators as well as in two versions for high compaction (with tamper and one or two pressure bars) or, alternatively, in the TP2 Plus version for particularly high compaction.

Compaction technology

VÖGELE sets standards in compaction values during paving: cutting-edge technology and the most advanced materials guarantee the outstanding performance and reliability of VÖGELE compaction technology. This applies to all VÖGELE compacting systems, from vibrators all the way to the VÖGELE high compaction system with tamper and pressure bars.

High compaction technology

The pressure bar(s) 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 over 98% can be achieved with VÖGELE’s unique high compaction technology – without rolling.

Telescoping system Extending Screeds

The operating principle of all VÖGELE Extending Screeds is the single-tube telescoping system. Even at maximum extension, half of the three-part, generously-sized telescoping tube is clamped, ensuring optimum stabilization. As the guiding system is arranged at a high level, this prevents any contact with paving mix.

Manufacturing technology Screeds

VÖGELE screeds feature leading-edge technology made possible by state-of-the-art production processes. The first of these processes, the precision cutting to shape of extremely wear-resistant sheet steel, takes place on laser cutting stations. Robots which operate continuously to a consistently high standard ensure long-lasting, stable welds.
