Coarse aggregate is placed in a rigid bucket and rodded with a tamping rod to Volume of bucket= ½ ft3 Weight of empty bucket 20.3 lb Weight of bucket filled with dry rodded coarse aggregate 69.6 Ib determine its unit weight. The following data are obtained: a. Calculate the dry-rodded unit weight If the bulk dry specific gravity of the aggregate is 2.620, calculate the percent voids between aggregate particles.
