For asphalt mixtures,the digital image technology has been used to obtain the internal structure,analyze the volume parameters and complete the computer-assisted design. These aspects have been hot research topics in the asphalt pavement technology area. In this paper,the relevant research results achieved by the author and his team are introduced,focusing on: ( 1) the statistics of the volumetric component of asphalt mixtures,the identification of the different components of asphalt mixtures and the extraction of the morphological characteristics of coarse aggregates,which are all based on the 2D digital image technology; ( 2) the 3D reconstruction of the internal structure of asphalt mixtures; and ( 3) the virtual mechanics test method. Meanwhile,the cases for the industrial applications of these research results are presented.
