基于材料基因组方法的沥青混合料基因特性综述及展望

The data-driven material genomic method has received increasing interest in the research and development of materials for the future. In particular, it has important guiding significance for asphalt mixtures with complex material compositions, significant structural randomness, and uneven material distribution. In order to promote the application of genomic methods to asphalt mixtures, this paper reviews the research progress of the main genetic characteristics that affect the performance of asphalt mixtures. First, the applications of the material genomic method in material engineering are summarized. Then, the basic material genomic characteristics of asphalt mixtures is introduced, including the asphalt component, asphalt microstructure, aggregate mineral composition, and aggregate morphology, and the relationship between the genomic characteristics and material performance is analyzed. Then, this paper introduces research on the microstructure of asphalt mixtures, including the relationship between void distribution, aggregate distribution, and aggregate contact and summarizes the research methods and the relationship between the characteristic genes and the performance of asphalt mixtures. Finally, a representative material genome system for characterizing the performance of asphalt mixture, genomic database, shared platform, and data mining methods are prospected.
