Calculating saturated bulk specific gravity (BSGssd):

BSGssd = (Wd + Wabs)/[Vi – Vw]

Where:
Wabs = Water absorbed into the sample, (Vi – Vf), ml
Wf = Weight of the flask, g
Vw = Volume of water [WT – (Wd + Wf)], ml
WT = Total weight of the flask, water and sample, g

Calculating dry bulk specific gravity (BSGd)

BSGd = Wd/(Vi – Vw)

Calculating conventional absorption

Use the Correlation Equation shown below to calculate the

Conventional Absorption as follows:

Conventional absorption, percent =

[(Absorption x 1.8243) + 0.0038] x 100
