• 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.
