• Abstract:
  Louisiana Department of Transportation and Development (DOTD) has spent substantial financial resources on various
  
  rehabilitation and maintenance treatments to minimize pavement distresses and improve pavement life. Such treatments
  
  include, but are not limited to, chipseal, crack seal, micro-surfacing, thin and thick overlays, and structural overlays.
  
  Unfortunately, DOTD has not conducted a full scale performance assessment and cost-effectiveness analysis of all the
  
  aforementioned treatments. A recent study completed by the Louisiana Transportation Research Center (LTRC)
  
  regarding the pavement management system (PMS) and performance modeling emphasized the importance of
  
  developing treatment performance and selection models. In this regards, the LTRC initiated a three-phase research
  
  study that addresses such needs by developing rigorous treatment performance and selection models that are specific to
  
  the mission and management strategies of DOTD. The following are the three phases.
  
   Phase I- Review and Project Selection
  
   Phase II- Performance Modeling and Costs and Benefits of Treatments
  
   Phase III- Model Integration and Training
  
  This final report focuses on the results of Phase I and Phase II of the study. Phase I is related to review of district
  
  pavement treatment practices and project selection for the development of pavement treatment performance models.
  
  Phase II deals with the performance modeling and costs and benefits of treatments. The data obtained from the Phase I
  
  was used to develop cost-effective pavement treatment performance and treatment selection models during Phase II of
  
  this study. Trigger values for optimum timing of pavement treatments and an approach to use the performance models
  
  cost effectively were established. All these findings will be integrated in the software development and training for
  
  DOTD staff to be completed during Phase III of this study.
