Feasibility of a Management System for Retaining Walls and Sound Barriers

摘要

Management systems for retaining walls and sound barriers are feasible, and can be modeled on existing systems for bridge management. A new management system requires the creation of data and procedures specific to walls and barriers, such as: an inventory record, elements and components, conditions states, inspection practices, maintenance actions, and asset valuation. In this study, proposals for data and procedures in each of these are examined. No impediment is found to full development of standard data and procedures for walls and sound barriers. Moreover, wall/barrier management can be implemented within existing software for bridge management such as AASHTOW are Pontis management system. This final report contains a proposed inventory record for walls and barriers, elements for walls and barriers, the use of components for hidden elements of walls, condition states, and appraisals, together with initial recommendations on inspection practice and intervals.
