Manual Work Banned, SUPER 800 Planned
SUPER 800 allows economical paving
Although the invitation to tender for building a pathway on top of an embankment along the river Rhine specified manual paving, construction company VBS GmbH proposed an interesting alternative. For works on the crest of the embankment in Cologne, Germany, VBS opted for a small VÖGELE SUPER 800 paver to get the job done and was awarded the contract.
When building the two-layer pathway, the VÖGELE paver demonstrated just how economically even small contracts, yet demanding high-quality results, can be handled. With their SUPER 800, a one-man operated machine, Vollmar Baumanagement und Service GmbH (VBS), Königswinter, placed the two layers on the 2.5km stretch within three days. Building the pathway along the river Rhine in Cologne's district of Stammheim was part of a large-scale project executed to protect the City of Cologne from flooding should river levels rise far above normal.
SUPER 800 allows economical paving
Curb stones were laid at the sides of the pathway, 3m wide, before surfacing the area in between. A level regulating layer of crushed stone (0/32) was placed first by the SUPER 800. This base 5 to 10cm thick, a job easily handled by the small paver, was followed by a layer of sand (0/5) in a thickness of 4cm. Due to use of the small SUPER 800 paver for building the combined foot and cycle path, surfacing works could be carried out clearly faster and took fewer manhours. What is more, the paver produced layers uniform in thickness and guaranteed constant precompaction. As a result, a pavement quality was achieved not attainable by the manual method.
Though of compact design, SUPER 800 never compromises. The paver does have been conceived for surfacing paths or smaller areas, but still it can be supplied with mix by large feed lorries as is common practice. The SUPER 800’s material hopper holds some 5 tonnes. When building the pathway on the embankment in Cologne, feed of the paver with mix was by 4-axle lorries which dumped their loads into the machine’s hopper without any problem at all.
Big hit for small contracts: SUPER 800
A pave width of 3m is not a real challenge to the small paver capable of handling surfacing jobs up to a maximum of 3.2m. Its AB 200 Extending Screed in TV version extends hydraulically from a basic width of 1.1m up to 2m. By fitting bolt-on extensions, the screed builds up to its maximum width of 3.2m
SUPER 800 successful in the markets
Since its launch into the markets in early 2005, the small SUPER 800 paver earned itself a remarkable reputation as a versatile piece of equipment. The paver has been designed not only for paving asphalt but also for placing crushed stone or similar materials in an economical manner. Many construction companies have soon recognized the small paver’s potential and use it on most varied surfacing contracts. By the way, SUPER 800 displays its capabilities for jobs booked by landscape contractors, too.
Paves also small areas true to line and level
SUPER 800 comes with NIVELTRONIC® SC, a System for Automated Grade and Slope Control, to ensure paving in absolute conformity with the specified layer thickness and/or specified slope. The grade and slope control system, easy to handle, allows precise control and monitoring of the screed for optimal accuracy of levels even when working on difficult terrain. The VÖGELE NIVELTRONIC® SC system has been specially tailored for use in pavers of the small equipment class and provides options matching the working environments typical of these machines. For tracing references, mechanical sensors, a slope sensor and a sonic sensor are available. When placing crushed stone on the embankment along the river Rhine, referencing was from the curb stones and mechanical grade sensors with skis were fitted on either either side of the machine.
Cologne puts flood defence system in place
After having seen, in 1995, the worst flooding in 100 years, the City of Cologne initiated a number of measures to better and adequately protect both citizens and properties and minimize damage should similar events occur in the future. An essential action taken was building steel armoured concrete walls and reinforcing the embankments along the banks of the river Rhine. In the Cologne district of Stammheim, the crest of an earthfill embankment had been removed over a distance of 2.5km in order to integrate steel piling into the embankment body. The height of the embankment was then raised to the sheet piling’s upper edge. Finally, a combined foot and cycle path of water-bound material has been built on top of the embankment fitting perfectly into the natural environment. The pathway is used not only by people enjoying a walk along the river, by joggers or cyclists, it also serves as a preferred route to work for many people employed at the nearby BAYER plant.
