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%
