An Experimental Study Of Angle Of Repose Of Aggregates And Its Correlation With The Shape Parameters

In the present work aggregates from a single source is used. The angularity levels of the aggregates are changed by crushing or polishing. The angle of repose values of crushed, natural and polished aggregates for different sizes are estimated. Subsequently an improvement in the method of measurement of angle of repose is suggested. Shape parameters of aggregates (Shape factor and Sphericity) are computed using Image processing the method given by MoraandKwan (2000). Finally dependency of angle of repose of aggregate heap on shape of aggregate has been found out.
