- 2. Penetration test Ductility test Viscosity test Softening point test Flash and fire point test Float test Solubility test Specific gravity test Spot test Water content Loss on heating test 2
- 3. PENETRATION TEST The penetration test determines the hardness or softness of bitumen. The instrument for measuring the hardness of bitumen. 3
- 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. 4
- 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. 5
- 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 6
- 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. 7
