Stabilization of unpaved shoulders over weak sub grade using geosynthetics


Shoulders are constructed next to rigid and flexible pavements to provide space for vehicles during an emergency, provide structural support for the roadway itself, thus increasing road safety. Shoulders can be paved or unpaved. Rutting and pavement edge drop-offs are common performance problems associated with granular shoulders, primarily caused by bearing capacity failure of the sub grade, vehicle-induced wind erosion, or vehicle off-tracking.

Edge drop-offs develop by surface runoff erosion, being hazardous to drivers and difficult to maintain such problems require more attention. These situations are typically repaired and mitigated by placing more material, grading and compacting it however, such a solution is considered temporary and does not address the factors causing the problem; therefore, the problem often recurs.

To accommodate heavy truck loads, eco grids can be used as reinforcement to stabilize. One of such technologies is also our Ecoraster grid, the original flexible porous plastic paving, designed and manufactured in Germany and also known as a geogrid or geocell. Our product is proudly produced by Purus Plastics GmbH and considering over 20 years of manufacture, we can guarantee 20 years of quality shoulder stabilization in most of environmental conditions.
