traffic load conditions. The geocells allowed efficient installation, with consistent concrete depth throughout— no voids or overfills. The GEOWEB GRC pavements require less concrete depth compared to reinforced concrete slabs, and no other form- work, expansion joints, or reinforcement is necessary. Leading theWay in Geosynthetics for Over Four Decades Engineers have successfully used geosynthetics to create better-performing pavements for civil and environmental projects for over 40 years. Their functions include separation, filtration, reinforcement, strengthening, drainage, bar- rier, and protection. While most published research and road specifications have focused on planar geogrids and geotextiles, geocells offer benefits that planar systems cannot. Geocellular confinement systems (geocells) are three- dimensional, honeycomb-like structures that confine and stabilize soils, preventing movement vertically and laterally. Geocells can reduce a pavement cross-section by 50-70 percent and allow for the use of fill materials of lower quality and lower friction angles, such as onsite-recovered gravel, coarse sand, or waste rock. Geocell technology has evolved over the past four decades, much as it has with geogrids and other planar geosyn- thetics. Presto worked with the US Army Corps of Engineers in the late 1970s to develop a grid confinement system that would maintain strength under heavy vehicle loading. The initial geocell applications were military road applica- tions over sand, using sand as the infill material. The geocell system and its applications have grown since the 1970s to be commercially available and used in civil and environmental projects globally, with the cost-savings ability to use low-quality fill materials often found on the project site.
