Specific gravity of water is 1.0.

• Specific gravity is the ratio of the density of a substance to the density of a reference substance.

• Water is often used as the reference substance for specific gravity calculations.

• The specific gravity of water is always 1.0 at standard temperature and pressure (STP).

Specific gravity of water, reporting officer, FDD method, and required compaction of GSB by MORTH are discussed.

• Specific gravity of water is 1

• Reporting officer is usually the immediate supervisor or manager

• FDD (Falling Weight Deflectometer) method is used to measure pavement deflection

• MORTH (Ministry of Road Transport and Highways) requires a minimum of 98% compaction for GSB (Granular Sub-Base)
