From page 29...
... 27 Combining a literature review with a survey and interviews, this synthesis project has attempted to determine: • The current state of practice in assessing the performance of mechanically stabilized earth (MSE) walls, particularly in the long term; • The direction of the state of practice; • What the current and effective practices are; and • What areas need improvement and/or research.
From page 30...
... 28 In summary, current effective practices for inventorying and assessing the performance of MSE walls include: • Use of inventory and assessment systems with features that are as simple to use and as objective as reasonably possible • Use of rating criteria that are specific to particular wall elements and/or conditions • Use of numeric rating scales that correspond to other scales already in use for other asset classes such as bridges • Incorporation of MSE wall inventory and assessment systems together with systems for other asset classes. Current effective practices for improving the performance of MSE walls include: • Use of pre-approval process for wall design and/or wall supplier • Provision of adequate internal and external drainage.
