Coloured asphalt, clean processing
Although paving coloured asphalt is a conventional process, it requires painstaking preparations. The paver’s material hopper, material handling systems and screed must be thoroughly cleaned, as must the feed lorries, to ensure that no residual black bitumen can contaminate the mix.
Needless to say, avoiding interruptions to the paving process is more important than ever. “With coloured asphalt, the crew has only one chance to get it right; the whole process has to run smoothly,” says Oliver Weiss. On confined job sites like the one in Baden-Baden, it is particularly important that the paving team can totally rely on the technology used.
A 10t material hopper ensures continuous paving.
On this job site, even the Compact Class VÖGELE paver needed every centimetre of available space to manoeuvre and the mix lorries faced even greater problems. It was not possible to transfer the coloured asphalt to the material hopper of the SUPER 1303-3i at every location due to the trees lining the route. The 10t hopper capacity therefore played a key role, ensuring that sufficient material was always available for continuous paving.
The VÖGELE paver’s professional material management system also helped the paving team deliver high quality results. The oscillating push-rollers ensured shock-free docking. The large conveyor tunnel, proportional control of conveyors and the powerful augers ensured an optimum flow of mix and even spreading in front of the screed.
