Abstract [en]

Changes and differences in homogeneity of asphalt concrete specimens during Marshall and Rolling-Wheel compaction are investigated by means of standard air-void content determination (AV) and X-ray Computer Tomography (CT). Following an earlier study on Gyratory compaction with the same objective and material, this study, again, focuses on expert. mental aspects serving as a basis for laboratories and producers to optimize compaction procedures and devices. The results demonstrate that X-ray CT is a powerful tool leading to a better understanding of compaction mechanisms, In this way, X-ray CT may be considered very suitable for developing improved laboratory compaction methods and procedures.
