How do you measure viscosity of bitumen?
Saybolt Furol viscosity test is used to determine viscosity of liquid bitumens. In this test, time in seconds is noted for 60 ml of the liquid bitumen at specified temperature to flow through an orifice of a specific size. The higher the viscosity of the bitumen more time will be required for a quantity to flow out.
How many bitumen tests are there?
List of IS Codes Related to Bitumen Testing
| Tests for Bitumen with IS codes | |
|---|---|
| Name of Test | IS code Number |
| Ductility test | IS: 1208-1978 |
| Softening Point test | IS: 1205-1978 |
| Specific gravity test | IS: 1202-1978 |
What is viscosity ratio of bitumen?
Bitumen is graded by viscosity at 60°C. For the purpose of this standard, the definitions given in IS 334 and the following shall apply. 3.1 Viscosity Ratio — It is the ratio of viscosity of residue from rolling thin film oven test to unaged bitumen, both measured at 60°C.
What is ductility test of bitumen?
property of bitumen which allows it to undergo deformation or elongation is called ductility of bitumen. The ductility of bitumen is measured by the distance in Cm (centimeter), to which the bitumen sample will elongate before breaking when it is pulled by standard specimen at specified speed and temperature.
What is the temperature of bitumen?
The bitumen temperature should be well within the limits specified. The viscosity of heated bitumen shall be between 150 to 300 conti stokes for which the normal temperature range for paving bitumen is between 150 to 177°C.
What does VG 40 mean?
VG-30 BITUMEN: VG-30 is primarily used to construct extra heavy duty Bitumen pavements that need to endure substantial traffic loads. VG-40 BITUMEN: VG-40 is used in highly stressed areas such as intersections, near toll booths and truck parking lots in lieu of old 30/40 Penetration grade.
Is code for test on bitumen?
List Of Codes Required For Laboratory
| Description | Designation |
|---|---|
| Methods of test for strength of concrete | IS: 516-1959 |
| Industrial bitumen | IS: 702-1988 |
| Procedure for testing hardness number of bitumen mastic | IS: 1195-1968 |
| Methods of sampling and analysis of concrete | IS: 1199-1959 |
What is softening point test?
The softening point shows the temperature at which the bitumen gains a certain degree of softening under the specifications of the test. This test is carried out by using the Ring and Ball apparatus.
What is the objective of lab testing for bitumen?
ASPHALT TESTING LABORATORY PENETRATION OF BITUMINOUS MATERIALS OBJECTIVES: To examine the consistency of a sample of bitumen by determining the distance in tenths of a millimeter that a standard needle vertically penetrates the bitumen specimen under known conditions of loading, time and temperature.
What is the maximum temperature of the bitumen?
Heat the bitumen to become fluid. The temperature of oven should not exceed the 90°C above the softening point (35 – 45°C). So, the maximum heating shouldn’t exceed 135°C. 2.
How do you test bitumen in asphalt?
ASPHALT TESTING LABORATORY 3. Pour the bitumen in the mold and take care not to disarrange the pieces of the mold. Pour the material in a thin stream back and forth from end to end of the mold until the mold is more than level full.
What is the penetration of bitumen?
Penetration Group # Readings Mean 90 1 92 93 93 2 95 96 (Table 8.5) Result: Penetration values are 92 and 95. Grade of Bitumen is 100 Pen. AC Grade is AC – 10. 8.6.
