虚拟集料库数据

虚拟集料库数据主要针对当前沥青混合料模拟中集料多以圆球代替、不能准确反映集料表面特性问题而进行的包含集料表面纹理特征的虚拟集料库的构建研究，基于改进的洛杉矶磨耗试验获取不同磨耗次数下的集料，通过三维蓝光扫描仪对磨耗集料三维形貌特征进行扫描，主要记录了4.75mm、9.5mm、13.2mm集料磨耗次数分别为0次、400次、800次、1200次下集料的三维形貌扫描数据，数据文件总大小为574.5MB

The Virtual Aggregate Library Dataset targets the limitation in current asphalt mixture simulation, where aggregates are mostly simplified as spheres and fail to accurately represent the surface properties of real aggregates. This work constructs a virtual aggregate library that incorporates the surface texture features of aggregates. Aggregates under various abrasion cycles were prepared through an improved Los Angeles abrasion test. Then, the 3D morphological characteristics of the abraded aggregates were scanned using a 3D blue-light scanner. The dataset primarily contains 3D morphological scan data of aggregates with nominal sizes of 4.75 mm, 9.5 mm, and 13.2 mm, which underwent abrasion cycles of 0, 400, 800, and 1200 times respectively. The total size of all data files is 574.5 MB.
