SPECIFIC GRAVITY OF BITUMEN EPUB

Specific gravity is defined as the ratio of the mass of a given volume of the bituminous material to the mass of an equal volume of water, the. Scope. This test method covers the determination of the specific gravity and density of semi-solid bituminous materials, asphalt cements, and soft tar pitches. The specific gravity of having bitumen as per IS: lies between.

The bottle is then removed and cleaned from outside.

Specific Gravity of Bitumen

The specific gravity of bitumen gravity bottle containing distilled water is now weighed. The bituminous material is heated to a pouring temperature and is poured in the above empty bottle taking all the precautions that it is clean and dry before filling sample materials.

A brass ring containing test sample of bitumen is suspended in liquid like water or glycerin at a given temperature.

A steel ball is placed upon the bitumen sample and the liquid medium is heated at a rate of 5 C per minute. Temperature is noted when the softened bitumen touches the metal plate which is at a specified distance below.

Generally, higher softening point indicates lower temperature susceptibility and specific gravity of bitumen preferred in hot climates.

Softening Point Test Setup Specific gravity test In paving jobs, to classify a binder, density property is of great specific gravity of bitumen. 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 specific gravity of bitumen 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.

Viscosity test Viscosity denotes the fluid property of bituminous material and it is a measure of resistance to flow.

At the application temperature, this characteristic greatly influences the strength of resulting paving mixes.

Pavement materials: Bitumen

Low or specific gravity of bitumen viscosity during compaction or mixing has been observed to result in lower stability values. Various petroleum products with specific gravity different pitch. Materials that have a lower specific gravity are lower boiling point thus one of the first applications of this parameter has been using it for the distillation of crude oil.

The specific gravity of applications including petroleum products are as follows: Assessment of specific gravity of a specified sample of bitumen Apparatus Pycnometer and balance Theory Specific gravity of bitumen gravity of bituminous material is known as the proportion of mass of specified capacity of substance to the equivalent volume of water, temperature of both of them approximating 27 degree Celsius.
