Analyses of Asphalt Pavement Distresses Using Formal Concept Analysis (FCA)

The literature has identified several possible causes of asphalt pavement distresses. Load-related distresses are apparent where the pavement has been over-stressed by traffic loads applied to its surface. Climate/durability-related distresses arise due to exposure to the environment. Other-related distresses are caused by actions not related to load or climate such as fuel spills or construction deficiencies. In this paper, information about fourteen asphalt pavement distresses frequently occurred on Taiwan's pavements was surveyed, structured and explored using formal concept analysis (FCA) method. FCA is an important mathematical tool for conceptual data analysis and knowledge acquisition. By using FCA, the concept lattice of the formal context of asphalt pavement distresses was created and studied. Based on the concept lattice and association rules derived from FCA, the causes of asphalt pavement distresses were understood. The findings are consistent with the literature and actual conditions. This study provides alternative solutions to understand the causes of asphalt pavement distresses. This study also clearly shows that FCA is a useful method for further exploring and extending information on pavement distresses.
