All data visible with a smartphone
“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,” says Stefan Trippe. Amongst other things, the contractor paved a 3.5 cm-thick surface course up to 12 m wide on two sections, measuring some 2 km each, ahead of and on the Aftetal Bridge. The team also counted on VÖGELE machines: a paver of the SUPER 1800-3i type worked in two strips in combination with the AB 500 TP1 Extending Screed. In the high compaction variant with tamper and pressure bar, the screed ensured a high level of precompaction which reduced the number of roller passes subsequently required. The contractor furthermore made use of a latest-generation PowerFeeder to prevent paver interruptions and to transfer the mix rapidly and smoothly: the high-performance MT 3000-3i Offset PowerFeeder. “The machine enabled us to facilitate smooth processes, stop the mix cooling down and create conditions for a high standard of paving quality,” says Stefan Trippe. “In combination with WITOS Paving Docu and Jobsite Temp, we were also able to view all the relevant data on a smartphone at all times, determine the ideal compaction window, take counter-measures if necessary and record all the processes associated with paving accurately, quickly and paper-free.”
Simple to use, a reliable check
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 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 QR code. The app and the paver are networked by WiFi, allowing information to be exchanged between the RoadScan temperature measuring system and a smartphone even when there is no mobile phone signal. “This is especially practical on jobsites like this which are remote and without the corresponding network coverage,” says Dennis Voss. He uses WITOS Paving Docu to record all paver and paving data such as pave widths, pave speeds and effective pave times. The application was also able to calculate continuously paving surface areas, quantities and densities. It was perfectly simple for Voss and his team to scan in delivery notes via QR code and view them at any time. “Compared to manual recording, of course, this saved us a great deal of time - and simultaneously, we could keep an eye on all the delivery notes and tonnages at all times,” says Dennis Voss. Voss and his team also used Jobsite Temp to monitor paving temperatures in real time. “The wind meant that we had to monitor temperatures continuously. The app helped raise the necessary awareness amongst all staff, including the roller operators, and determine the ideal paving and compaction window.” Roller operators were likewise able to use the app to view their own position and distance from the paver and to define exclusion zones.
