• Abstract:
  Manual surveys of pavement cracking have problems associated with variability, repeatability, processing
  
  speed, and cost. If conducted in the field, safety and related liability of manual survey present challenges
  
  to highway agencies. Therefore automated processes for cracking analysis have been sought after in the
  
  past decades. Processed cracking results need to be compiled based on a standard or a protocol so
  
  pavement engineers can apply the results in design and management. Pavement cracking protocols vary in
  
  details. Cracking definitions in the Highway Performance Monitoring System (HPMS) and the
  
  Mechanistic-Empirical Design Guide (MEPDG) represent two efforts in defining cracking applications
  
  for pavement condition monitoring and prediction modelling of pavement condition in design
  
  respectively. This paper presents the findings of using a fully automated process with the Automated
  
  Distress Analyzer (ADA) to establish a viable method for analyzing cracks based on 2D laser images for
  
  HPMS and MEPDG. It is determined that automated survey is possible for both protocols as long as
  
  careful design and implementation are made and errors are controlled in the process as much as possible.
  
  In addition, an analysis of wheelpath wandering and its effect on cracking analysis is conducted by
  
  varying positions of wheelpaths and their sizes.
