Road construction project uses digital solutions

By Catrin Jones24 January 2022

Vögele machines and smartphone solutions were chosen by Franz Trippe GmbH for help paving the road on the Aftetal bridge, west of Bad Wünnenberg in Westphalia, Germany.

The project, due to be completed in Spring 2022, involves building a bypass to relieve traffic congestion and is part of a large-scale traffic corridor to make the Hochsauerland region more accessible.

Working almost 70m up: the contractor used machines and digital solutions from Vögele to pave the surface course of the Aftetal Bridge.

The height of the bridge and exposed position in the terrain means that, even in good weather, there is always a wind blowing which rapidly cools the paving mix. By implementing the WITOS Paving Docu into the project it allows paving and machine data to be recorded via smartphone and analysed at the end of the day.

In combination with RoadScan, contractors can also record and analyse paving temperatures. During paving, current temperature data can be viewed via the display of the paver operator’s console. The new Jobsite Temp app furthermore enables the foreman and other users to access temperature data and supplementary data via smartphone in real time.

It shows current pave speeds, screed width, the positioning of the paver and the position of the mix transfer point including delivery note information.

Managing director, Stefan Trippe, says, “By combining WITOS Paving Docu with RoadScan, we created the conditions on the one hand for checking paving temperature continuously under the difficult weather conditions and on the other, for meeting the quality and documentation requirements.”

The technical prerequisite for WITOS Paving Docu is a telematics module fitted in the paver; Jobsite Temp requires RoadScan as well.

The core of this system is the infrared camera including a GPS receiver fitted to the paver’s hardtop. Paving supervisor, Dennis Voss, was then able to launch both apps on his smartphone on the job site and link to the paver via a QR code. Both the app and the paver are networked by WiFi, which allows the information to be exchanged between the RoadScan temperature measuring system and a smartphone without mobile signal.
