Stability prediction for asphalt mixture based on evolutional characterization of aggregate skeleton
نویسندگان
چکیده
The aggregate skeleton significantly influences the deformation resistance of asphalt mixtures. A stable has good interlocking effects and load transfer ability to resist mixtures during loading. Therefore, methodology accurately evaluate morphology based on mechanism inside is great value predict mixture stability. objective this study validate stability from perspective evolutional morphologies skeleton. three main steps, which are as follows: (1) initial characterized evaluated; (2) topological non-topological evolutions external loading characterized; (3) strain energy stress distribution contact regions in used analyze prediction mixture's Simulations uniaxial displacement-controlled tests cylindrical specimens drilled a field-compacted test track were conducted, 7.5, 15, 22.5, 30 s selected time points simulation Results indicate that better load-bearing capacity when its contains more chains with higher evaluation indices, proves reliability using proposed method.

More than 90% of Malaysian roads are constructed using asphaltic concrete. However, previous investigations of asphaltic concrete have mainly concentrated on the macroscopic properties of the composite materials based on the assumption that the mixtures are homogeneous and isotropic. This paper applies a digital image processing technique to compare the orientations of coarse aggregate particle...

Asphalt mixture is heterogeneous in nature; therefore, macroscopic parameters alone cannot describe the mechanical behavior of the mixture. In recent years, the arrangement of the aggregate particles in terms of spatial and directional distributions, and contact points are considered as the internal structure of asphalt. The main purpose of this paper is to investigate the microstructural chara...
