Grid Iron: Minnesota Enhances its Geotechnical Asset Performance

When the Moving Ahead for Progress in the 21st Century (MAP-21) federal law called on state departments of transportation to institutionalize asset management and performance standards as they incorporate innovation into their practices and policies, the expectation was that there would be an improvement on past practices, with an enhanced stewardship of the U.S. infrastructure. It was also expected that a sustainable transportation system would be delivered that could support opportunity and prosperity. This article posits that transportation agencies need to look beyond the traditional asset categories of pavement and bridge condition, in order better understand the impact of all transportation system assets in order to manage them cost effectively and responsibly. Along these lines, the Minnesota Department of Transportation (MnDOT) is utilizing geogrid to enhance geotechnical asset performance, as an example of actions recommended by the American Society of Civil Engineers to raise the grade of roadway infrastructure in Minnesota. The project, detailed in this article, includes geotechnical assets such as embankments, slopes, retaining walls and constructed subgrades.
