Many cities are faced with deteriorated street pavement. Often the underlying problem is a weak subgrade soil. In the past these subgrades were undercut and a premium fill or additional aggregate base was imported. Recently cities have turned to geosynthetic or chemical remedies. A Tensarâ geogrid solution is very popular for three key reasons. First, the cost of geogrid and a reduced thickness of aggregate base is very competitive. Second, the polypropylene geogrid will last a lifetime thus allowing it to perform consistently year after year. Third, the time saved by reconstructing a street with Tensarâ geogrid is a benefit that is highly recognized and greatly appreciated by both the city and by the residents who are impacted the most during a recon-struction project. Readily available, Tensarâ geogrid saves time and requires no specialty equipment.
