- 요약The state of Georgia has been managing transportation assets following costeffective operation, maintenance, and inspection protocols to achieve the goals and objectives defined in Georgia's Transportation Asset Management Plan (TAMP), which aligns state practices with federal objectives to enhance and preserve U.S. infrastructure. Georgia transportation corridors consist of various asset classes, such as pavements, bridges, culverts, retaining walls, and slopes, to name a few. The Georgia Department of Transportation (GDOT) manages bridges and pavements through its respective divisions, which, under recent TAMP policies, periodically assess the state of the assets and establish long-term life cycle strategies based on factors such as criticality, deterioration, and financial constraints. However, geotechnical assets (e.g., retaining walls, slopes, embankments, etc.) have been overlooked, rarely tracked, and not subjected to similar standards, although their potential failure may lead to significant traveler delay, property damage, and safety concerns for surrounding communities. Because of this interdependence, the need to manage geotechnical assets under similar or improved strategies is necessary to maintain federally required statewide levels of safety and service in transportation corridors.This research seeks to enable a new geotechnical asset management (GAM) program in Georgia by developing a structured framework and a GIS-based computational system for implementing it in sequential phases. The proposed framework and system are developed based on the guidance in the National Cooperative Highway Research Program (NCHRP, 2019a) "Geotechnical Asset Management for Transportation Agencies - Research Report 903" but also considers inventory, inspection, and risk-based managementpractices successfully implemented in U.S. transportation agencies when required. The developed GIS-based computational system fosters the proposed GAM framework for Georgia and enables inventory, risk-based inspections, and decision-making processes to efficiently allocate funding depending on asset deterioration and safety and mobility risks. Furthermore, consistent with the recommended approach in the NCHRP (2019a) and FHWA (2017) reports, the value of a lean start, which can be continuously refined, is emphasized. The geotechnical assets to be considered were defined in consultation with the Geotechnical Bureau of the Office of Materials and Testing (OMAT) at GDOT, including retaining walls, slopes, embankments, and bridge foundations. They have been selected as they are critical pieces of the infrastructure that provide mobility, safety, costeffectiveness, and economic viability of the overall transportation system in Georgia.The proposed GAM framework comprises a six-step methodological sequence: Definition and Acceptance Criteria, Inventory, Inspection, Risk Analysis, Results, and Evaluation and Refinement. In the Definition step, relevant geotechnical features for different geotechnical assets are considered, separating them into mandatory and optional based on the ease of collecting them and their relative importance for the state. In the Inventory step, this work facilitates (1) inventory during design, which includes the inventory of geotechnical assets in upcoming construction projects; (2) as-built inventory, considering the inventory of assets right after construction; and (3) inventory of existing assets. The Inspection step focuses on assessing the asset condition, identifying vulnerable surrounding assets, and assigning maintenance inspections and the periodicity based on the qualitative evaluation of failure consequences and deterioration. Subsequently, in the Risk Analysis step, the Level of Risk (LOR) is calculated as a result of the inherent risksassociated with safety and mobility failure consequences on the portion of the analyzed corridor. Lastly, in the Results and Evaluation steps, GAM metrics should be presented to facilitate decision-making processes for selecting optimal operation and maintenance strategies, allocating funds, and refining strategies to enhance the GAM program and improve ongoing workflow steps.
