Veier og arbeidsplattformer uten faste dekke
Unpaved roads are a feature of construction sites around the world. But while they have to cope with extremely heavy loads, these working platforms often have to be sited on weak or variable ground. That’s where Tensar’s geogrids, incorporating clever working platform design – and in particular the innovative TriAx® – can help reduce costs by mechanically stabilising granular materials very efficiently. When compacted over the geogrid, the granular particles project through the triangular apertures and are mechanically confined. This interlock, combined with the grid’s near-uniform 360 degrees stiffness creates an efficient stiff composite layer for a working platform or unpaved road.
Geogrids can be used in working platform design to mechanically stabilise unbound granular layers and so either reduce their required thickness or increase their bearing capacity prolonging their life.
Structural improvement – unpaved roads, including short-term site haul roads to much longer- term unsurfaced access roads (such as for onshore windfarm sites) can be effectively stabilised using geogrids to prolong their life, increase their bearing capacity and reduce the amount of granular material used.
Piling platforms and storage areas – Working platforms for safe operation of heavy tracked plant such as piling rigs and cranes.
