Size Distribution of Coarse-Grained Soil by Sedimaging
An image-based method has been developed for determination of particle-size distributions of coarse-grained soils in the 0.075–2.0 mm range. The percentage of fines is also determined. The test is referred to as sedimaging because it analyzes an image of a soil that has been rapidly sedimented through water to sort the particles by size. The sorting facilitates image analysis based on wavelet transformation. This paper details the sedimaging hardware, image analysis method, and test procedures. Parallel sedimaging and sieving tests on nine soils of different colors, gradations, and particle shapes showed nearly identical results. Sedimaging holds several advantages over sieving, including decreased testing time, lower energy consumption, less equipment maintenance, and improvement of the work environment.
