Ammann vibratory plates at work

APH 6530 at work during a development project

The two mounds known as the Pirmin Hills situated in the Ortenau district in the heart of the town of Sasbach needed to be levelled to create space for a new supermarket. Four multi-family dwellings and an underground garage will be constructed in parallel in the direct vicinity of the supermarket. All in all, around 50,000 m3 of material had to be moved as the site had a significant incline and needed to be levelled for construction work.

One of the challenges facing general contractor Thorsten Lebfromm was to ensure that trucks could continuously enter and exit the site safely and easily – despite a substrate composed of clay-based topsoil. The job was assigned to an Ammann APH 6530 Hydrostatic Compactor with its unique, market-leading triple-shaft exciter system.

Once the topsoil had been removed, the substrate needed to be continuously compacted to provide a load-bearing surface for the trucks. Thorsten Lebfromm’s workforce then installed and compacted a 30 cm layer of recycled material. This work was followed by the installation and compaction of an asphalt layer. The vibratory plate was able to use its full potential due to the ever-changing substrate and proved that even different surface types are by no means a challenge for the APH 6530.

Matthias Pfaff of the Reichert Servicecenter in Sinzheim, who had previously collaborated in the riding arena project, was once again the contact partner for the general contractor. “Our customer Mr. Lebfromm was once again delighted with the performance of the APH 6530. The vibratory plate’s flexibility in view of different substrate types and its compaction performance are simply one of a kind. They enabled us to complete the project successfully in three weeks.”
