- 요약The work performed in this dissertation focused on the sustainability of transportation roadside infrastructure, particularly the geotechnical assets including mechanically stabilized earth (MSE) retaining walls and stormwater best management practices (BMPs). To provide a framework for sustainable geotechnical infrastructure development, it is important to understand the life cycle of assets, which typically consists of five phases: planning and design, material extraction and manufacturing, construction, operation and maintenance, and decommissioning.In this work, life cycle assessment (LCA) and life cycle cost analysis (LCCA) were conducted in two phases (planning and design, and construction) to evaluate environmental and cost impacts based on design and construction inventory parameters. The main components contributing to the structural stability and long term performance of MSE retaining walls include backfill material, reinforcement material and wall height; consequently, those components were compared to identify sustainable wall design options to support decision-making in wall design. In the construction of MSE walls, the selection of backfill materials resulted in the most significant environmental impacts, including pronounced smog formation and fossil fuel depletion. When comparing backfill materials, crushed stone was the least sustainable option when compared to gravel and sand. The selection of reinforcement material was also environmentally significant, as steel strips can cause substantial impacts depending on the density of reinforcement spacing specified in the design process.Highway roadside infrastructure stormwater BMPs were studied in terms of their environmental impacts as a function of contaminant treatment, designs, and construction materials to identify the most effective green infrastructure choices. In some stormwater BMPs, the specification of large volumes of mulch or concrete for drainage structures requires caution in the planning and design phase, as they can result in relatively significant environmental impacts. Additionally, contaminant treatment is significant in the design, and emphasis on improving heavy metal removal and preventing nutrient export in stormwater treatment systems were the important factors for optimizing performance as green infrastructure.Finally, the environmental and cost impacts, and performance of assets during the operation and maintenance (O&M) phase of the infrastructure lifetime was evaluated. Because the Georgia Department of Transportation (DOT) currently lacks a management system for MSE walls during operation, guidelines for wall management were developed, and management strategies were compared from a sustainability perspective. A wellorganized management system and tools can extend the life expectancy of MSE walls and minimize significant environmental, economic, and social impacts with low expected expenses. For stormwater BMPs, the performance of an enhanced swale operated by the Georgia DOT was evaluated and the estimated contaminant removal efficiencies were compared with previous studies. The BMP (enhanced swale, sand filter, and check dam) effectively removed contaminants with no clogging, drainage problems, or metal accumulation during the period of study.
