Job site interrupted by construction of new bridges
However, of all the technologies employed, AutoSet Plus was the most important on the job site: after all, the section is being widened to 18.5m in each direction, which is why the bridges along the route also need to be replaced. As a result, the job site is split into many different sections of relatively short length, over which the entire asphalt package has to be laid. The asphalt package consists of a mortar base on which the asphalt layers, comprising a base, binder and surface course, are placed. For noise abatement purposes, they are mainly made of porous asphalt.
AutoSet Plus does away with manual input
“Normally we have to reset all the paving parameters every time we reposition the paver,” explains Henry Moser, Paving Foreman at Johann Bunte Bauunternehmung GmbH & Co. KG. “The same applies to every new layer if a different mix is to be paved at a different thickness and pave speed.” In a construction project such as the widening of the A10, the settings for the VÖGELE SUPER 1900-3i and SUPER 2100-3i paver would have to be re-entered repeatedly several times a day. “And when there’s time pressure as well, it goes without saying that mistakes can arise,” Moser adds. “That’s why we were glad of the assistance AutoSet Plus provided on the job site.”
High precision at the push of a button
On the A 10, each mix for the various asphalt layers had to be paved with identical parameters. To ensure that they were, the two paver operators saved the settings after each layer as a paving program whenever this layer was laid for the first time. This was quick and easy to do, because most of the settings can be taken over automatically by AutoSet Plus.
After completing one of the sections, Bunte transported the 2 VÖGELE Highway Class pavers to the next one – and the operators were able to continue working with identical settings at the press of a button. “That enables us to ensure that every asphalt layer is laid and precompacted in the same way on each section,” adds Jürgen Schimang, Asphalt Coordinator at Bunte. “So AutoSet Plus gives a high degree of security: to the paving team, because there is one less potential cause of errors; to us, because we have more process reliability; and to the client, because they can be sure that every metre of every layer is paved identically.”
