Abstract

This paper reports the initial findings of a study to assess the use of close range terrestrial photogrammetry to model the wear of asphalt surface course mixes. Slabs of 10mm asphalt concrete were subjected to accelerated wear under laboratory conditions using the University of Ulster Road Test Machine. Macro-texture profiles were generated from photo stereo pairs. The output data was compared to texture depth change determined using the conventional volumetric sand patch test. The initial findings suggest that this methodology based on digital imagery can be used to model highway surface change and provide improved understanding of the processes at the tyre road surface interface
