The leading road research and standards institute in Holland conducted controlled field trials for geosynthetics reinforcement of road bases. Test data was based on deformation and stiffness trials of full-scale structures in controlled sites (enclosed hangars). PRS-Neoweb™ was the only geocell manufacturer among 7 leading geogrid manufacturers. In addition, PRS-Neoweb was also the only geosynthetic reinforcement tested that could accommodate inferior aggregate material as the road base infill. The results showed that PRS-Neoweb had the highest Road Base Thickness Reduction Factor of any tested product (up to 72% average unlimited), and substantially exceeded the known values for geogrids.

The reduction factor for PRS-Neoweb, in a field trial with 7 leading geogrids, was so high that it exceeded the known values for geogrids. The results showed that PRS-Neoweb had the highest Road Base Thickness Reduction Factor of any tested product (0.72) and substantially exceeded the test limits.
