void ratio of sample 1 at 600 mm depth is about 0.7, which is much higher than the initial pre tsunami void ratio estimated to be less than 0.5 on the compacted surface. Assuming this range of void ratio and an associated saturated unit weight of about 21 kN/m3, the critical hydraulic gradient, icr, can be estimated from: icr= (Ys/Yw) - j

Bulk Density and Void Percentage Test for Aggregates

The bulk density and void percentage of aggregate can be evaluated using standard test methods of applicable codes such as ASTM C 29/C29M-17a, IS: 2386 (Part 3) – 1963, or BS 812-2:1995. The procedure provided in this article is based on the specification of ASTM standard ( ASTM C 29/C29M-17a). The bulk density or unit weight is the weight
