GATE Civil Engineering (CE) 2014 Shift 2 Solved Paper

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 the bitumen (VFB) in the Marshall sample (in %) is _______
