The document discusses various tests conducted on bitumen, including penetration tests to determine hardness, ductility tests to measure adhesion and ability to stretch, viscosity tests to measure resistance to flow, softening point tests using a ring and ball to determine temperature susceptibility, and flash and fire point tests to identify ignition temperatures. In total, nine different tests are outlined that examine key properties of bitumen like hardness, adhesion, flow resistance, temperature performance, and ignition points.

3. PENETRATION TEST
 The penetration test determines
the hardness or softness of
bitumen.
 The instrument for measuring
the hardness of bitumen.

4. DUCTILITY TEST
 This test measure the adhesive
properly of bitu-men and it’s
ability to stretch.
 The test is conducted at 27*c and
at a rate of pull of 50mm per
minute.
 The distance up to the point of
breaking of thread is reported in
centimeters as ductility value.

5. VISCOSITY TEST
 Viscosity is defined as inverse of
fluidity.
 Viscosity is the general terms for
consistency of bitumen and it’s
measure of resistance to flow.
 High or low viscosity during
mixing or compaction has been
observed to result in lower
stability values.

6. SOFTENING POINT TEST
 The softening point of bitumen is
usually determined by ring and
ball test.
 Generally higher softening point
indicates lower temperature
suscepti-bility and is preferred in
warm cli-mates.
 The softening point of various
bitumen grades used in paving
jobs from 35* to 70* c

7. FLASH AND FIRE POINT
 Flash point:-The flash point of a
material is the lowest temperature
at which the vapour of a substance
momentarily takes fire in the from
of a flash under specified
condition of test.
 Fire point:-The fire point is the
lowest temperature at which the
material gets ignited and burns
under specified test conditions.
