Comparative simulation analysis of pavement technology for a decision support system in the U.S. road renewal industry

摘要: In the United States, State Departments of Transportation (DOTs) and other public sector owners highway infrastructure have been facing poor road conditions, significant funding shortfalls, increasing traffic congestion over past decade. response to challenge, U.S. renewal industry is developing partnerships explore ways improve roadway performance while taking into consideration overall lifecycle costs rehabilitating countless miles existing roads. To identify those pavement strategies that will likely most cost-effective highest in industry, researchers developed a technology analysis framework consisted two analyses: economic non-economic analyses. Furthermore, four experts believe dominate during next ten years were analyzed, including: Dense-Grade Hot Mix Asphalt (HMA), Stone Matrix (SMA), Open Graded Friction Course (OGFC), Warm (WMA). study, our demonstrated extent which impact quality associated with construction maintenance life each strategy. The analyses resulted rankordering pavements based on their performance. research ultimately combined benefits achieve an rank-ordering efficient as follows: (a) (b) (c) (WMA), (d) Open-Graded (OGFC).
