Geogrids are polymer grid structures used in soil reinforcement. This article explains how geogrids work, and the advantages of using geogrids in road construction. Geogrids can provide either uniaxial or biaxial reinforcement. Placed within an aggregate layer, the grid provides a surface against which the aggregate grabs while helping distribute the traffic load above. This interaction greatly reduces migration within the aggregate layer, a chief cause of road failures. Geogrids minimize the amount of aggregate needed and the risk of intermixing. They also improve the strength of the base aggregate layer. Although geogrids are well accepted in road construction, general awareness and user knowledge of them is just now filtering out. For optimal benefit, contractors should seek out educational resources to ensure that they are applying the appropriate design and construction methods when using geogrids.
