Asphalt paving without joints and with crown
The asphalt runway at Jade-Weser Airport consists of two asphalt base courses and one surface course. The lower courses were paved by a SUPER 1900-3i. This tracked paver was equipped with WITOS Paving Plus. The primary paver was supported by a SUPER 1600-3i and a SUPER 1800-3i for the final paving stage, the surface course. The machines worked “hot to hot” with an overlap of around 20cm – and thus without joints.
The paving strips were selected so as not to create a centre joint: the SUPER 1900-3i worked a width of 7.5 m in the centre of the runway and paved a crown. Beside it, the two other VÖGELE pavers paved two strips with a transverse slope, creating a width of 15 m.
The primary paver finally paved the outer strips, making a total width of 30m. The fact that it was possible to work practically continuously throughout was due not least to the use of WITOS Paving Paving Plus.
Valuable support, simple to operate
”The system impressed us a lot right back at the planning stage, because it simply calculated a lot of the values itself - for example, the quantity of asphalt required. If the capacity of the planned mixing plant is too low, the system issues a warning,” said Tim Gassmann. This was also the case with a number of the planned strips in Wilhelmshaven. It was demonstrated by the calculation completed by the WITOS Paving Control Paving Control planning and control module – and was why the senior site manager arranged a second mixing plant in good time to cover peak demand.
Ease of operation is at least as important as accurate function. “WITOS Paving is extremely practical. It can simply be used, whatever the weather. The software functions are easy to understand. As a result I was quickly able to see what key added value the system offers. I wouldn’t want to be without it now,” insisted works supervisor Theo Hülsmayer, who operated the WITOS Paving Paving Plus JobSite module on an outdoor PC on the job site itself. This visualized all the key paving parameters for him on a tablet or outdoor PC.
