Abstract
In order to investigate the mico-scale void structure of water-based epoxy emulsified asphalt muxtures under different molding methods,this paper utilized X-ray CT scanning and digital image processing techniques by comparing and analyzing the void ratio,void distribution,and morphological characteristics of the mixtures under three molding processes(vibration,rotational compaction,and Marshall compaction),the mechanism of the molding method on the formation of the internal structure was revealed.The results show that vibration molding and rotational compaction can effectively improve the uniformity of the void distribution within the mixture and significantly reduce the proportion of large-sized voids,thereby constructing a more stable frame-work structure.Compared to the traditional Marshall compaction,these two molding methods demonstrate sig-nificant advantages in enhancing the performance of the mixture and can be selected as the preferred molding methods in the mix proportion design of water-based epoxy emulsified asphalt mixtures.关键词
