Key Features & Specs

The extending screed for all SUPER pavers of the 8 ft class

The AB 500 Extending Screed combines with all VÖGELE tractor units featuring a basic width of 8 ft. 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.

  • Heating System

    VÖGELE has put its faith in electric screed heating for decades. This extensive experience, in combination with continuous further development, means that VÖGELE screeds are now brought to temperature quickly and evenly.

  • Compaction technology

    VÖGELE sets the benchmark with products that deliver a phenomenal degree of precompaction in the paving process. 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.

  • Manufacturing Technology

    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.

  • High-compaction technology

    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 over 98% can be achieved with VÖGELE’s unique high-compaction technology – without rolling.

  • Telescoping system

    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 telescoping system is arranged at a high level, this prevents any contact with paving mix.
