REVIEW OF IMAGING TECHNIQUES FOR CHARACTERIZING THE SHAPE OF AGGREGATES USED IN ASPHALT MIXES

Image processing and analysis techniques are versatile tools for rapidly characterizing the shape properties of engineering materials. This paper provides a review of efforts directed at developing image analysis techniques for characterizing aggregate shape properties with focus on aggregates used in asphalt mixes. It discusses the different aspects of aggregate shape, and the imaging indices developed for the purpose of quantifying these aspects. It also summarizes the different experimental procedures used to measure these indices. The correlation between the imaging indices and other conventional methods for measuring aggregate shape, and asphalt mix performance are also discussed.
