1. Assessment of aggregate structure in porous asphalt using X-ray computed tomography
University essay from KTH/Väg- och banteknikAbstract : X-ray computed tomography is a technique that has been successfully utilized to characterize internal microstructure of asphalt mixtures. The city of Linköping (Sweden) developed an action plan to reduce noise; accordingly KTH and VTI developed a method to determine air void content in porous asphalt using x-ray computed tomography and an image processing software called ImageJ.
