2 Page 1/8 Tips & Tricks from Practical Applications 19 Reduction Systems for the Tightest Pave Widths VÖGELE offer cut-off shoes for pave widths narrower than the basic width of the AB 200, AB 340, AB 500 and AB 600 Extending Screeds. These are fitted to the side plates. In this issue of Tips & Tricks, we tell you what to look out for when using pave width reduction systems. What to do when the pave width is narrower than the screed width? When backfilling tight trenches or channels for gas, water or tele-communication infrastructures, the required pave width is often narrower than the screed s basic width. So if you choose to pave manually, you risk a loss of quality often associated with a much rougher surface. The smarter option: using pave width reduction systems for the AB 200, AB 340, AB 500 and AB 600 Extending Screeds. These guarantee a consistently high pavement quality, while significantly reducing the time required for the paving work.

3 Page 2/8 Function and Installation of Systems for Pave Width Reduction VÖGELE s system for pave width reduction reduces the space for the mix in front of the basic screed. Please take note of the following before beginning with the installation: 1 Secure the paver against rolling away. Set the ignition switch to the 0 position. Then shut down the machine. 2 Remove the ignition key. 3 For safety reasons, lower the screed onto wooden blocks.

The pave width is infinitely variable. The cut-off shoes form a kind of funnel that narrows the space in front of the basic screed.

An appropriate flat iron (3) is attached to the cut-off shoe depending on the desired layer thickness and the degree of subsequent compaction by rolling. This allows the pave width to be varied infinitely. The cut-off shoe has a defined width by which the pave width is reduced.

6 Page 5/8 Paving with Systems for Pave Width Reduction A certain amount of experience is needed when paving with systems for pave width reduction. Our tips will enable you to easily achieve a very high level of pavement quality. Tip 1 The right flat iron for the right layer thickness When using the systems for pave width reduction for AB 500 and AB 600 screeds, you can choose between flat irons of 5mm or 10mm. This depends on the degree of subsequent compaction by rolling and the material being paved. A 10mm flat iron is available for the cut-off shoe of the AB 340 screed. Pave width reduction system for AB 500 screed with 10mm flat iron.

7 Tip 2 Page 6/8 Automated grade and slope control possible with systems for pave width reduction The VÖGELE systems for automated grade and slope control can be combined with noncontacting acoustic sensors (in this case the multi-cell sonic sensor), or with mechanical grade sensors. When using the VÖGELE system for pave width reduction, the screed floats in precisely the same way as when paving without cut-off shoes. This means the thickness of the layer concerned is variable via the screed tow point rams and controlled via the system for automated grade and slope control, i.e. NIVELTRONIC Plus in the case of the AB 340, AB 500 and AB 600 Extending Screeds, and NIVELTRONIC or NIVELTRONIC SC (Single Channel) in the case of the AB 200 Extending Screed. This guarantees accurate paving results and superb compaction when working with the system for pave width reduction.
