Which test sample is used for tests for tar and bitumen?
Which test sample is used for tests for tar and bitumen?
The test is conducted by using Ring and Ball apparatus. A brass ring containing test sample of bitumen is suspended in liquid like water or glycerine at a given temperature. A steel ball is placed upon the bitumen sample and the liquid medium is heated at a rate of 5 degree per minute.
What is viscosity of bitumen?
In North India, vg20 is used for road construction in hot mix asphalt. The standard penetration value of bitumen viscosity grade VG-20 is 60 mm at 25 °C. The absolute viscosity of VG-20 bitumen is 1600 to 2400 poise at 60 °C.
Is 73 a bitumen test?
This standard was first published in 1950 as ‘Specification for asphaltic bitumen and fluxed native asphalt for road making purpose’ which was revised in 1961 to change the grades of material and incorporate the methods of test as per 1S1201to IS 1220:1958 ‘Methods for testing tar and bitumen’.
What is the density of bitumen?
1.01-1.05 g/cm 3
The density of bitumen is 1.01-1.05 g/cm 3 in the temperature range of 25°C to 85°C [63] .
How do we measure the 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 do you get bitumen samples from asphalt?
Bitumen samples are mainly obtained from the bitumen testing equipment with the lower portion of heated tanks, using a sampling tube. Sampling may be carried out at the plant where asphalt is being manufactured, or at the site of construction.
What is the ductility of bitumen?
The ductility of bitumen is expressed as the distance in centimeters to which a… Digital Penetrometer: The cone penetrometer consists of: Aluminium base with levelling screws and spirit level. Chromed vertical rod with Digital readout of the penetration values. Readings in mm and inch, with 0,1 mm resolution.
What is cut back bitumen distillation equipment?
Cut Back Bitumen Distillation Equipment: This apparatus is used for the examination of cut-back asphaltic materials by the distillation test. It consists of: Distillation flask Condenser Adapter Shield Shield and flask support Electric heater with ..
What is the difference between bitumen and asphalt?
Bitumen is a petroleum product, obtained from crude oil, is an important binder material having good thermoplastic and load bearing properties. It is easy to melt and use and therefore used in the application of pavement and reads. Asphalt is another name used for Bitumen and bitumen extractor.
