Geogrid is a geosynthetic material that acts as a retrofit layer, slopes, etc., the geogrid has a large tug strength of up to 180 kN, this geosynthetic material is well fitted for roadwork that have a low basecoat under 2%, for example on a highway Are in poor soil structures for example when used on hollow roads, it can be overcome, geogrid can also be used on railroads, and on lands prone to landslides. Geogrid has been commonly used for more than 25 years. For a quality geogrid, you can see at http://www.maccaferri.com/my/products/geogrid-macgrid/.
While people have gained widespread benefits as a solution to problems related to roads built on soft or problematic soils, the use of competent subgrades has been less common. Clearly, established design methodologies are now available that allow design engineers to measure the benefits of using geogrids to extend the life of pavement plans. This approach can be applied to the design of major highways or light sidewalks that are associated with local housing or the development of retail stores.
Geogrid technology has evolved steadily since the product was first introduced in the early 1980s. Geogrids initially quickly gained popularity in the civil engineering industry, mainly because of their ability to provide simple, cost-effective solutions across various roads and classes of separation applications.
A geogrid is a regular grid structure of a polymeric material used to strengthen the soil or other related engineering geotechnical materials. Products are generally classified as uniaxial geogrid or biaxial geogrid, depending on whether their strength is largely in one direction or two. Uniaxial geogrid is mainly used in classroom separation applications such as retaining walls and steep slopes, biaxial geogrid used primarily in road applications.
Use of biaxial geogrids in base strengthening applications. In this situation, the basic soil has been provided as through the use of basic soil improvement techniques. One of the major failure mechanisms of sidewalks under these subsoil conditions is the grooves resulting from the progressive lateral movement of the aggregate base during traffic load
The number of lateral movements can be greatly reduced by inserting the biaxial geogrid in, or at the bottom, the bottom foundation layer, the partial penetration of coarse aggregate particles through the geogrid holes and subsequent compaction results in aggregate particle “interlock mechanics” or “enclosures”.
