摘要：	Highway networks in the United States have been suffering from poor operational and structural condition states for the past decades. The consequent congestion problems often result in major delays, safety issues, and large amounts of additional fuel consumption and greenhouse gas emissions. With limited funding available, transportation agencies are placing more emphasis on maintenance, repair, and reconstruction (MRR) practices in order to preserve and restore roadway conditions. Innovative MRR techniques have proved effective or shown great potential in addressing problems associated with poor condition levels of aging asphalt roadway infrastructure with reduced economic, social, and environmental impacts. In this project, the research team investigated various innovative MRR techniques (e.g. warm mix asphalt, full depth reclamation, cold in-place recycling, and intelligent compaction) and developed decision support tools to assist transportation agencies in identifying the most appropriate MRR techniques in consideration of several technical, economic, social, and environmental factors. More specifically, a survey of state departments of transportation (DOTs) has been conducted, and the results have been utilized in developing decision support tools featuring a decision flowchart and multi-criteria decision making (MCDM) modeling tools using Fuzzy analytical hierarchy process (FAHP) and analytical network process (ANP). The decision support tools have been validated through feedback from NYSDOT officials and case studies based on actual asphalt roadway MRR projects in the State of New York.
