Calculate the percent voids between aggregate particles that have been compacted by rodding, if the dry-rodded unit weight is 88.0 lb/cu ft and the bulk dry specific gravity is 2.701.

Answer:47.7%

Explanation:

The void content in the aggregate using the bulk density can be determined by the rodding method, as follows:

%Voids = 100[ (SxW) - M] / (SxW)

Where;

S=Bulk dry specific gravity

W=density of water (62.3 lb/cuft)

M=Bulk density of the aggregate (88 lb/cuft)

℅void=100[ (2.701*62.3) - 88] / (2.701*62.3)

=100[168.2723-88]/168.2723

=8027.23/168.2723

=47.7%
