Characterization of Aggregates and Asphalt Concrete Using X-Ray Computerized Tomography A State of the Art Report

摘要

X-ray computerized tomography is a viable non-destructive method for material characterization. Its capability of obtaining threedimensional (3D) material structure enables the characterization of aggregates and asphalt mixture on a new horizon promising applications in characterization, modeling and computational simulation to optimize mix design, predict performance and conduct forensic studies. This paper reviews the fundamentals of X-ray Computerized Tomography (XCT), its capability, and recent development in applying this tool to characterize aggregates and asphalt mixtures.
