Abstract: The limitations of the mainstream method for the sieve analysis based on the digital image processing were analyzed and the advantages of industrial X-ray CT technique were pointed out. 5 specimens were produced according to the coarse aggregate size range of asphalt mixture. The volumetric parameters of the coarse aggregate were obtained by industrial CT scanning. The accuracies of the 3 methods for calculating the volumetric parameters were compared. The 3-dimensional surface contours were characterized by the spherical harmonic transformation, thus the L, W dimension positions were got, and the control planes passing the sieve were intercepted. The size of the square sieve that the aggregate particle can pass was determined by a series of digital image processing techniques. The validation results show that by means of the new method based on CT scan images the 3-dimensional virtual sieve analysis of the coarse aggregate could be realized more accurately.

Key words: road engineering, coarse aggregate, digital image processing, X-ray CT, spherical harmonic transformation, virtual sieve analysis
