• Abstract:
  Recent changes in pavement materials costs have impacted the competitive environment relative to the
  
  determination of the most cost effective pavement structure for a specific highway project. In response, State
  
  highway agencies have renewed their interest in using alternate pavement type bidding procedures to determine
  
  the appropriate pavement type. This research project developed an alternative bidding procedure for pavement
  
  projects. Not all highway projects are candidates for alternate bidding. A step by step procedure can help identify
  
  candidate highway projects for alternate bidding. In addition to developing a deterministic life cycle cost (LCC)
  
  analysis model using I40 interstate pavement data, the research team also developed a novel approach, namely,
  
  realistic LCCA model. This approach uses the association rule mining technique to find and probabilistically
  
  organize various treatment patterns applied to pavements in the past. A case study conducted in this project
  
  revealed that this realistic LCCA model is more reliable and is expected to provide better predictions on LCC.
  
  Moreover, since this approach is based upon the historical performance of pavements, it is expected to be easier to
  
  draw consensus between the asphalt and concrete industries in calculating life cycle costs. A spread sheet based
  
  program is developed for ODOT to calculate LCC for flexible and rigid pavement alternatives. This program
  
  enables ODOT to enter project information such as project scope, analysis period, estimated unit prices,
  
  miscellaneous items, mobilization, and construction added costs for asphalt and concrete pavement projects and
  
  obtain deterministic and realistic LCCs of both pavement types as well as LCC factor which should be used during
  
  the alternate bidding process.
