High Tension Guard Cable Inspection and Life Cycle
The Missouri Department of Transportation (MoDOT) began utilizing guard cable along interstate routes in the early 2000s, and since that time has installed more than 800 miles of guard cable on divided highways. For this project, MoDOT aims to take a deeper dive on the life of these systems, installation and repairs, and material characteristics after impact(s), among other items, to better understand this type of asset as it has been utilized by the Department for almost 20 years. Some of the objectives include analyzing the material properties after multiple impacts, reviewing installation and repair procedures, reviewing installation inspection and maintenance records along with available crash reports, conducting field inspections of a representative sample of locations, and conducting a life cycle assessment.
