Pavervia tunnels consist of precast segments made in ?declared series? pursuant to M.D. 14/01/2008 "TECHNICAL STANDARDS FOR BUILDINGS" and ART. 9 OF LAW No. 1086/1971.
Thanks to the Paver solution, the dimensions and overall dimensions of classic box tunnels can be complied with.
The structure is made from shoulder type precast sections able to adapt to any foundation solution required by the particular characteristics of the site (isolated foundation, strip foundation, on piles).
Numerous jobs have been done directly by the Pavervia division using own personnel and means.
Generally speaking, an assembly team in standard conditions is able to assemble about 25 linear m of shoulder sections a day.
The installation sequence can only be defined according to the specific nature of the worksite because the segments are independent the one from the other and do not require shoring up at all.
Stringent inspections during production ensure the durability of the materials.
