• Abstract:
  This study investigated project management level solutions to optimizing resources, minimizing costs
  
  (including user costs) and time for PCC pavement rehabilitation projects. This study extensively
  
  evaluated the applicability of the Construction Analysis for Pavement Rehabilitation Strategies
  
  (CA4PRS) software program as a potential solution to achieve the goal. The usability of the CA4PRS
  
  was assessed by conducting knowledge inventory surveys at GDOT and ODOT as well as conducting
  
  four case studies. The pre and post knowledge inventory surveys indicated that there was a general
  
  understanding that the CA4PRS could be used as an excellent tool to help decision makers effectively
  
  plan PCC pavement rehabilitation projects. The four case studies indicated that, in addition to using the
  
  CA4PRS, there should be further efforts in order to develop an effective construction plan for a PCC
  
  pavement rehabilitation project. Some major recommendations are a) ODOT/GDOT must put efforts to
  
  collect CA4PRS input data and develop a database for reliable analysis using the CA4PRS, b)
  
  ODOT/GOT also need to use the CPM scheduling method and the CA4PRS together because the
  
  current CA4PRS considers only six major activities in project scheduling, c) A simulation program such
  
  as the Cyclone program can be used to determine the optimal number of resources of major activities.
  
  Based on the findings of this study, this project has designed an improved planning procedure to find
  
  the most efficient project phasing and closure scenario for PCC pavement rehabilitation projects. The
  
  procedure involves a quantitative analysis on every potential project execution scenario using the
  
  CA4PRS, the CPM method and a simulation tool.
