.... Analysis of the particle size distribution showed the presence of high sand size fractions in both RCA and RAP base materials compared with virgin CA base materials. This indicated the recycled materials were crushed/milled to smaller size fractions or degraded under freeze-thaw cycles and traffic loads...

...Andrea Ventola; Roman D. Hryciw Sed360 is a largely automated system for determining image-based particle size distributions (PSDs) of sands. A sedimented soil specimen contained in a 25.4-mm (1-in)-diameter circular acrylic tube sits atop a rotating stage. While the tube rotates, a camera captures...

... enough. In this work, we first define a simple way of finding the particle size distribution without using any special device, only with a commercial camera and a well-known free image-processing software. Once defined, we analyze the error magnitude and dispersion of the method with different samples...

...Jean-Sébastien Dubé; Julie Ternisien; Jean-Philippe Boudreault; François Duhaime; Yannic Éthier Sampling particulate matter for particle size distribution (PSD) analysis is a task routinely performed in geotechnical and geoenvironmental engineering. Pitard (2019) mentions that “for a sample...
