• Abstract:
  Tight budgets and dwindling state and federal revenue hinder efforts of transportation agencies to resurrect pavements in poor ; condition. As a “stop-gap” measure, some agencies simply allow roads to deteriorate to gravel. However, this approach can be ; costly over the long-term and often results in dissatisfied users. ; This research project will identify construction treatments and/or materials that can be used to extend the service life of pavements ; in poor condition. These treatments are intended to be economical and practical “stop-gap” measures until permanent and ; affordable solutions are available. They are not an “alternative” to reconstruction. ; New emerging pavement rehabilitation strategies are being developed and tested at the Recycled Materials Resource Center ; (RMRC) at University of Wisconsin-Madison using superior properties of recycled materials (e.g., fly ash stabilized reclaimed ; asphalt pavement and recycled concrete aggregate) to extend service lives of roadways. Efforts are underway to evaluate their ; performance by comparative economic and environmental life cycle analyses. These methods show great promise as cost-effective ; measures to treat poor pavements to achieve stop-gap or longer life cycle results. ; The research will create tools for selecting and analyzing strategies for pavements in poor condition. The tools, created for ; Minnesota, will support future decision-making based on cost effectiveness by providing a synthesized method of life cycle cost ; analysis (LCCA) and life cycle assessment (LCA). This research will illustrate design strategies that offer Minnesota greater ; economic and environmental sustainability in resurrecting dead roads, resulting in maintaining a healthy road system.
