Synthesis of Information Related to Highway Practices. Topic 55-03. Asset Management Practices for Mechanically Stabilized Earth Walls

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 are too young to meet the design life. Additionally, design guidelines, construction materials, and protocols have significantly evolved since the technology was first adopted. Therefore, the early MSE walls constructed using the original design guidelines and construction protocols may be inadequate according to the current state of practice. As a result, some of these early structures have failed unexpectedly due to their deterioration over time. Deterioration processes in MSE walls may involve different types of mechanisms with different onsets and progress at different rates. Collectively, these mechanisms contribute variably to the overall deterioration rate of a wall during the service life of the wall. Currently, there is no standard practice for managing MSE wall assets for state departments of transportation (DOTs). The objective of this synthesis is document state DOT asset management practices for MSE walls in their inventories.
