Abstract
This research analyzed the characteristics of aggregate contact chain networks based on complex network theory. The contact chain network was extracted using Digital Image Processing (DIP) technology and Three-Dimensional (3D) reconstruction technology. The change rule of the contact chain network of asphalt mixture was analyzed using the complex network theory. From the results of the analysis, the filling particles existed during the compaction. The 4.75–9.5 mm and 9.5–13.2 mm aggregates may rotate to increase the stability of the skeleton structure. The clustering coefficient of the aggregate increased as the asphalt mixture was compacted, and the aggregate with a small size had a larger clustering coefficient. The distribution of shortest path length in each compaction stage obeyed the Gaussian distribution. The average shortest path length decreased with the increase of the compactness of the specimen, indicating that there was a good correlation between shortest path length and compactness.
期刊介绍：
Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests:
Formation and synthesis of particles by precipitation and other methods.
Modification of particles by agglomeration, coating, comminution and attrition.
Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces).
Packing, failure, flow and permeability of assemblies of particles.
Particle-particle interactions and suspension rheology.
Handling and processing operations such as slurry flow, fluidization, pneumatic conveying.
Interactions between particles and their environment, including delivery of particulate products to the body.
Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters.
For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
