摘要

Performance-based planning is an important tool for allocating treatment resources across a pavement network from a set of candidate treatments with a budget constraint. Existing research focuses on improving allocation decisions through changes in the optimization algorithm without considering the consequences of how optimization analyses are framed. In this paper, both environmental and economic performance is evaluated for different problem framing in the form of different treatment strategies that consist of treatment materials, treatment types, and evaluation period. Results show that the proposed strategy that uses both concrete and asphalt, different treatment types, and a long evaluation period could reduce GHG emissions and improve pavement network performance based on the Iowa U.S. route network. Compared to a conventional 5-year asphalt-only strategy, proposed strategy can accomplish this with an annual budget that is 32% smaller and reduce associated GHG emissions by 21%. These results contribute to achieving a sustainable pavement network.
