Mechanically stabilized earth (MSE) walls are widely used in transportation projects due to their cost-saving, time-efficient, and resilient nature. However, most of the walls constructed so far have been built too recently to allow assessment of whether or not they would meet the desired design life. Additionally, design guidelines, construction materials, and protocols have evolved greatly since the technology was first adopted.
NCHRP Synthesis 644: Asset Management Practices for Mechanically Stabilized Earth Walls, from TRB's National Cooperative Highway Research Program, documents state departments of transportation asset management practices for MSE walls in their inventories. Relevant practices include those related to maintenance and rehabilitation of deteriorated walls, inventory and assessment, and development of risk and life-cycle costs.
