All data available at a glance on the phone
"With WITOS Paving Docu in combination with RoadScan, we were able to continuously monitor the paving temperature while meeting all the quality and documentation requirements, despite the harsh weather conditions," says Trippe. The project included paving a 1.4 in thick and up to 39.4 ft wide surface course on two approximately 1.25 mile long sections before and on the Aftetal valley bridge. The team also utilized machine technology from VÖGELE: a SUPER 1800-3i paver working on two lines in combination with the AB 500 TP1 extending screed. In the high compaction version featuring tamper and pressure bars, the paving screed ensured a high degree of precompaction, so reducing the number of rolling passes needed subsequently. To avoid paver stoppages, and to transfer the material quickly and smoothly, the contractor also deployed the latest-generation MT 3000-3i Offset PowerFeeder. "The machine technology enabled us to streamline our processes, prevent the material from cooling down, and meet all the preconditions for achieving high paving quality," Trippe adds. "In combination with WITOS Paving Docu and Jobsite Temp, we also had all the relevant data constantly to hand on a phone. This meant we could identify the ideal compaction window, take corrective action as and when necessary, and document all the paving-related processes quickly and precisely in paperless form."
Easy to use, reliably monitored
WITOS Paving Docu requires a telematics module installed in the paver, while Jobsite Temp needs the addition of the RoadScan contactless temperature measurement system. The core of that system is the infrared camera, incorporating a GPS receiver, mounted on the paver's roof. On the job site, paving foreman Dennis Voss was then able to launch both applications on his smartphone and connect to the paver using a QR code. The app and the paver are connected over a WLAN network, so information can be exchanged between the RoadScan temperature measurement system and a smartphone even where there is no cell signal. "That's especially useful on remote sites like this one, where there's no network coverage," says Voss. He used WITOS Paving Docu to record all paver and job data, including working widths, pave speeds, and effective paving times. The application also continuously calculated the paved surface areas, material quantities, and surface densities. Voss and his team were able to easily scan and view delivery notes at any time using a QR code. "That obviously saved us a lot of time compared to manual data input, and also meant we had a constant overview of all the delivery notes and tonnages," Voss comments. Voss and his team also monitored paving temperatures in real time using Jobsite Temp. "Because of the wind, we had to continuously monitor the temperatures. The app helped to sharpen awareness among all the staff, including the roller operators, and allowed us to identify the ideal paving and compaction windows." The roller operators could also view their own position and distance from the paver, and define exclusion zones, on the app.
