- W642321146 abstract "Aiming to improve decision processes for pavement asset management, this paper describes a tool for quantifying economic benefits of pavement research products. The tool appears suitable for evaluating benefits of research, technology development, and pavement management system implementation. The paper provides background about challenges, approaches, and trade-offs in performing benefits assessments and highlights some previous evaluations. The paper describes a cost-benefit analysis method that was initially developed and successfully used in Australia and later enhanced and applied in South Africa to assess benefits of pavement research. While highlighting case studies in both countries, the paper focuses on an ongoing case study applying the Australian/South African tool to evaluate pavement research in California. This case study evaluates benefits from research using accelerated pavement testing that validated expected performance of innovative mixes and designs before using them in rehabilitating a high-traffic urban interstate freeway in the Los Angeles area. Net present value and benefit-cost ratio are calculated for agency and user cost savings. Results show benefit-cost ratios ranging from about 5 to 30. Sensitivity analysis was performed and is recommended for interpretation and use of cost-benefit analysis results. Although local conditions differ significantly between the three countries, the method was used successfully and consistently showed positive results. The Australian/South African tool may be suitable for prospective analysis and offers potential advantages such as analysis of alternative outcome scenarios, treatment of uncertainty, and validation interviews with implementers of research findings. Recommendations are suggested for further evaluation and use of the method." @default.
