In a Marshall sample, the bulk specific gravity of mix and aggregates are 2.324 and 2.546 respectively. The sample includes $5 \%$ of bitumen (by total weight of mix) of specific gravity 1.10 The theoretical maximum specific gravity of mix is 2.441 . The void filled with bitumen (VFB) in the Marshall sample (in \%) is
