A 3-D Specimen and Multiple Functional Digital Tester for Performance Evaluation of Asphalt Mixes

Recent developments in x-ray computerized tomography (XCT) imaging and computational simulation have made it possible to characterize the properties of asphalt concrete through reconstructing its three-dimensional (3D) microstructure and computational simulation based on the 3D microstructure. The digital representation of the real 3D microstructure (not a simulated 3D or two dimensional (2D) microstructure) of a physical specimen is named Digital Specimen. It is the digital counterpart of the physical specimen in every required detail. A digital specimen is usually represented as a 3D digital image and naturally includes scientific visualization of the initial/evolved microstructures and behavior related to rutting, fatigue cracking, and thermal cracking.
