Specific Gravity Bottle

Specific Gravity Bottle

---

It may be defined as the binder; density property is of great use. In most cases bitumen is weighed, but when used with aggregates, the bitumen is converted to volume using density values. The density of bitumen is greatly influenced by its chemical composition. Increase in aromatic type mineral impurities cause an increase in specific gravity. The specific gravity of bitumen is defined as the ratio of mass of given volume of bitumen of known content to the mass of equal volume of water at 27 °C. The specific gravity can be measured using either pycnometer or preparing a cube specimen of bitumen in semi solid or solid state. The specific gravity of bitumen varies from 0.97 to 1.02.

Features:-
First and foremost job that is to be done is wash the density bottle and dry it in an oven at 105 °C to 100 °C. Cool it in the desiccators.
