The generation of virtual aggregate, close to realistic aggregate by numerical tool, is a key step in investigating the mechanical properties of asphalt mixture from the mesoscopic level. To verify the accuracy of assemblage of aggregate, this paper is based on the improved algorithm of random cutting technology previously proposed, using PFC3D editing program to establish a vibrating sieve, and the reliability of the improved algorithm was verified by sieving test. The results show that the improved algorithm of the irregular polyhedron random cutting technique proposed by the author can ensure that the gradation of the aggregate is consistent with the actual, and the sieving test can be used to evaluate the quality of the virtual aggregate based on PFC3D.
