Ammann AFT 300-2 Places Mix Between Tram Tracks
When the narrow space between tram tracks needed paving, the Ammann AFT 300-2 Compact Paver went to work.
The paver was utilised in downtown Brno in the Czech Republic by Firesta – Fišer, rekonstrukce, stavby a.s. while working on a project to rebuild a tram.
The crew from Firesta is very experienced, but it was their first time working with the AFT 300-2. The transition was seamless.
“Machine control did not cause any difficulties for the experienced crew,” said Pavel Pawlica of Firesta. “Machine setup is standard and is rather simple compared to competitive machines.”
The paver worked at a width of 143 cm while placing mix between the tracks. “The width of the paver was very important,” Pawlica said. “It fit the rail track gauge perfectly. Otherwise, we would have been forced to pave manually.”
Manual paving can take considerable time and put a great deal of stress on a crew. In addition, mix placed by hand is not as smooth and dense as is asphalt that is leveled and precompacted by a paver.
The quality of the work was good, as proven by an on-site governmental inspector. “The surface and compaction were examined by the inspector several times and there was no problem with the quality,” Pawlica said.
The paver was also able to complete work on the outside of each track, typically working at widths of 180 cm.
The project took about five days – a time frame that was considerably shorter than if the work had the work been done manually. Three lifts were placed for a distance of 4800 metres. In all about 1500 tonnes of asphalt were used.
Mix was loaded directly into the hopper by a skid-steer loader, which could easily clear the front of the hopper. The loader would approach from the front of the paver, unload the material and then return for more mix. This all could be accomplished without stopping the paver. “The paving process was continuous, even for extended distances,” Pawlica said.
It was just another way the AFT 300-2 perfectly matched the jobsite.
“It fit the project very well and helped us a lot,” Pawlica said.
