The following observations are made while testing aggregate for its suitability in pavement construction:
i. Mass of oven-dry aggregate in air = 1000 g
ii. Mass of saturated surface-dry aggregate in air = 1025 g
iii. Mass of saturated surface-dry aggregate under water = 625 g
Based on the above observations, the correct statement is
A
bulk specific gravity of aggregate = 2.5 and water absorption = 2.5%
B
bulk specific gravity of aggregate = 2.5 and water absorption = 2.4%
C
apparent specific gravity of aggregate = 2.5 and water absorption = 2.5%
D
apparent specific gravity of aggregate = 2.5 and water absorption = 2.4%

Correct : a
