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.

Totally 60 semi-circular bending specimens cored from superpave gyratory compactor with three groups of notch depths are tested at the temperature of-10 and 20℃ The experimental results reveal good repeatability in EAM characterization. The tensile strength ratio of SCB to the indirect tensile test is at a range of 1.4 to 1.7, and the ultimate strength of EAM is exponentially dependent on the notch depths. At the test temperatures, the critical J-integral value of EAM is much higher than that of hot mix asphalt with thermoplastic asphalt binder. The response mode of EAM changes from ductile mode to brittle mode and the fracture energy increases 30% when temperature decreases from 20 to-10℃, while its critical J-integral value decreases only 15%.
