Abstract: Two-dimensional boundary coordinates of 99 irregular aggregates were extracted after digital processing of asphalt concrete CT images. The modified Fast Fourier Transformation method (FFT) was used to obtain the fitting functions of those coordinates and the irregular particle form database was established. With the established database and PFC2D software, a program for two-dimensional virtual mechanical simulation of asphalt concrete with irregular particles was written. Taking three gradations as an example, under the same void, virtual simulations of Double punch test and Split test were carried out. The test results show that the presented method can automatically generate digital specimen and the generated digital specimen can satisfy the requirements of micro mechanical properties numerical analysis of asphalt concrete.

Key words: road engineering, asphalt concrete, fast Fourier transformation (FFT), virtual simulation, finite element method (FEM)
