Barcelona bypass
26 January 2011
Construction of the B-40 orbital motorway at Barcelona cost € 1,9 billion, and consisted of a near 50 km bypass around the Catalan capital.
To build the new section near Viladecavalls, contractor Pabasa used the Vögele Super 3000-2, a paver designed for large-scale projects.
The width of the job site varied between 12 m and 18 m. The pave width was between 10,5 m and 15,5 m, with the wearing course placed in one pass. The Super 3000-2 features a maximum laydown rate of 1600 tonnes/h and a maximum pave width of 16 m.
A high-performance 6-cylinder Deutz diesel engine developing 300 kW at 1800 rpm is installed in the Super 3000-2. However, Vögele said the paving team was surprised by the efficiency of the machine. For paving wearing course to a thickness of 4 cm and in widths between 10 ,5 m and 15 ,5 m, the engine's ECO Mode was totally sufficient. ECO Mode decreases the engine output to 292 kW at 1500 rpm, thus also reducing both fuel consumption and noise emissions.
In order to ensure that the supply of mix from the feed lorries to the paver went as smoothly as possible, a Vögele MT 1000-1 Mobile Feeder was deployed upstream of the Super 3000-2.
