Strata’s client wanted to strengthen the internal roads of their manufacturing facility of wind turbine towers. The site consisted of weak clayey soil with a CBR (California Bearing Ratio) of 15%, which needed to be strengthened for traffic movement and to minimize the effects of ruts due to vehicular passes. Strata faced challenges due to the weak subgrade on which the road was to be built; the road needed to cater to very heavy loads, fatigue, and rutting.

Strata’s team of geotechnical experts suggested removing a layer of thickness of the road crust and adding a layer of StrataWeb® geocell. Introducing StrataWeb® in the granular base or sub-base improved the pavement’s longevity and economized the overall crust thickness. The three-dimensional structure helped in confining the soil and distributing the load to a wider area, thereby reducing stresses on the overall crust thickness. The reduction of the layer of thickness of road crust saved 20% of the cost, and the installation of StrataWeb® is faster and has less ongoing maintenance.
