• Abstract:
  Louisiana experimented with various techniques and treatments to control reflective cracking since the
  
  1970s. The objective of this study is to evaluate and compare different reflective cracking control
  
  treatments by evaluating the performance, constructability, and cost-effectiveness of pavements built
  
  with these treatments across the state. To achieve this objective, a survey of current state practices
  
  identified the treatment methods that are used or that had been used to delay and mitigate reflective
  
  cracking in composite pavements. Based on this survey and a thorough review of LADOTD databases,
  
  pavement sections built with reflective crack control treatment methods were identified. Projects with
  
  sufficient years in service and with available untreated segments were selected for detailed
  
  performance and economic evaluation. In total, the performance of 50 different sites that were
  
  constructed with various treatments was evaluated for a period ranging from 4 to 18 years. Among
  
  various treatments that were analyzed, saw and seal, and chip seal as a crack relief interlayer showed
  
  the most promising results in terms of performance and economic worthiness. The cost effectiveness
  
  of fiber-glass grid was not validated as compared to regular HMA overlays. Stress absorbing
  
  membrane interlayer and high strain asphalt crack relief interlayer (STRATA®) showed mixed results
  
  in terms of performance. In addition, there were an insufficient number of projects for paving fabrics
  
  to allow for drawing conclusions on the cost-effectiveness of this treatment method.
