Image analysis techniques to determine fine aggregate angularity Conference Paper uri icon

abstract

  • The ability of fine aggregate angularity (FAA) test procedure to distinguish aggregates with good and poor performance in HMA and to examine the potential of image analysis methods of quantifying fine aggregates angularity was evaluated. Twenty-three fine aggregates from different parts of the USA were tested using ASTM C 1252, Method A. The FAA test method does not consistently identify angular, cubical aggregates as high quality materials. The image analysis methods exhibited good correlations among themselves. Those crushed cubical fine aggregates with FAA values lower than 45 showed high angularity in all three imaging methods.
