The project was based on the influence to the asphalt mixture volumectric property by the different compaction method (Marshall Compaction, Roller Compaction, Gyratory Compaction, Vibratory Compaction), a great deal of the experiments has been done with the consideration of the pratical construction. A lot of studies were carried out, such as the study of asphalt mixture image inquiring technique--"Colour Method", the feasibility study of the application of the 2D digital image processing technique on the asphalt mixture and the utiliztion of this technique on the compacting properties analysis of asphalt mixtures. A good beginning and foundation was made for the application of the digital image processing method on the study of the 3D asphalt mixture voluemetric components constitute.
