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.

How do you measure viscosity of bitumen?

To determine the industrial viscosity of bitumen, road tar, and cutback bitumens. The industrial viscosity of bitumen is measured by determining the time taken by 50 cm3 volume of material to flow from a cup through a specified orifice in standard conditions of temperature and a specified temperature.

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.

Why bitumen extraction test is done?

Bitumen Extraction Test is used to determine the percentage of bitumen content present in the asphaltic pavement by cold solvent extraction.

What is Marshall test?

The Marshall Test is a popular and proven method to measure the load and flow rate of asphalt specimens, beginning with compaction into molds using manual or automated Marshall Compactors, and conditioned in a Water Bath at the specified temperature.

What is float test of bitumen?

The float test of Bitumen measures the consistency of the bitumen when it is not possible to determine the consistency by penetration test or viscosity test. Consistency of Highly viscous bitumen is tested by float test. The distillation residues and residues from emulsion are tested by float test.

How is ductility test done?

A bend test helps provide a visual indication of the ductility of the material. The guided bend test method requires the specimen to be loaded at its center point with a mandrel or plunger while being supported at the ends. The specimen is bent to a predetermined angle or until the specimen fractures.

What is Marshall test of bitumen?

The basic Marshall test consists essentially of crushing a cylinder of bituminous material between two semi-circular test heads and recording the maximum load achieved (i.e. the stability) and the deflection at which the maximum load occurs (i.e. the flow).

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.

What type of bitumen testing equipment do we offer?

What is bitumen laboratory mixer?

Bitumen Laboratory Mixer for mixing of Bitumen for making different types of test specimens for mix design in the laboratory. The apparatus comprises of A motor driven mixer which simultaneously imparts two motions to the mixing paddle i.e. revolving and planetary.

What is cut back bitumen distillation equipment?
