Bitumen Density Formula

Equation for calculate bitumen density is,

Density of Bitumen / Asphalt = (W₂ - W₁) / (W₃ - W₁) - (W₄ -W₂)

Where,
W₂ = Weight of Pycnometer with Bitumen
W₁ = Weight of Empty and Dry Pycnometer
W₄ = Weight of Pycnometer with Distilled Water and Bitumen
W₃ = Weight of Pycnometer with Full of Water at Temperature 25°C
