Question
a) The following data are available in a density-void analysis for Marshall method of
mix design.
Specific gravity:
Coarse aggregate = 2.759
Fine aggregate = 2.905
Mineral filler = 2.699
Asphalt = 1.010
% by weight of total mix:
Coarse aggregate = 51.45
Fine aggregate = 34.24
Mineral filler = 7.35
Asphalt = 6.96
Maximum specific gravity of paving mixture = 2.438
Bulk specific gravity of compacted mixture = 2.344
Calculate: Bulk specific gravity of the total aggregate, Effective specific gravity
of the aggregate, Asphalt absorption of the aggregate, Voids in the mineral
aggregate, Voids filled with asphalt, and Air voids in the compacted mixture.
