Flash Point Test The flash point test determines the temperature to which an asphalt can be safely heated in the presence of an open flame. The test is performed by heating an asphalt sample in an open cup at a specified rate and determining the temperah1re at which a small flame passing over the
The penetration test is performed to determine the penetrate value of the bitumen and a softening point test is conducted to determine the viscosity point of the bitumen. The flash and fire point test is performed on a particular bitumen grade to identify the safe temperature of bitumen for reliable work.
This test is done to determine the softening point of asphaltic bitumen and fluxed native asphalt, road tar, coal tar pitch and blown type bitumen as per IS: 1205 – 1978. The principle behind this test is that softening point is the temperature at which the substance attains a particular degree of softening under specified condition of the test.

• Important – Direct tensile test (for low temperature cracking), fracture toughness test (for low temperature cracking), bitumen fatigue test (for fatigue) and relationship with site data (for adhesion). • Desirable – Creep ZSV/repeated creep tests (for deformation resistance), DSR
The test gives an idea of the temperature at which the bituminous materials attain a certain viscosity. Bitumen with higher softening point may be preferred in warmer places. The softening point should be higher than the hottest day temperature, which is anticipated in that. area otherwise bitumen may sufficiently soften and result in bleeding ...

For a bitumen of a given penetration (determined. at 250C), the higher the softening point the lower the temperature sensitivity. This test is done to determine the softening point of asphaltic bitumen and fluxed native asphalt, road tar, coal tar pitch and blown type …
The softening point value is particular significance for material which are to be used as thick films, such as joint and crack filler and roofing materials. Research has shown that, for conventional pacing grade bitumen, the ring and ball softening point temperature is the same as that which would give a penetration of 800 d-mm.
softening point Bitumens are viscoelastic materials without sharply defined melting points; they gradually become softer and less viscous as the temperature rises. The softening point of bitumen can be determined through the use of a ring-and-ball apparatus immersed in distilled water (30 to 80°C) or USP glycerin (above 80 to 157°C).

1.1 This test method covers the determination of the softening point of bitumen in the range from 30 to 157 °C [86 to 315 °F] using the ring-and-ball apparatus immersed in distilled water [30 to 80 °C] or USP glycerin (above 80 to 157 °C).
Hence, The average value of the two temperatures of both balls is the softening point of bitumen. So, in this way Softening point test of bitumen is performed. IS 73 has specified different criteria so, code should be followed before application of bitumen for specified load. Report of test. Temperature for ball (A) = 46 degree centigrade.
Softening Point Ring and Ball is the second oldest test method applied to bitumen, after needle penetration. It is the temperature at which a bitumen sample in a ring has had a deformation of 25 ± 0,4 mm by a ball while heated. Defi nition and Terminology Softening Point Ring and Ball: Temperature at which bitumen and bituminous binders attains

ductilità di bitumen, the amount with which bitumen is determined at a temperature lower than the softening point. Meaning of the test of the ductilità del Bitume: the test of the ductilità of the Bitumen sample is one of the main bitumen tests to be conducted in front of the construction of the road.

EXPERIMENT NO. 12 SOFTENING POINT OF BITUMEN (RING-AND-BALL APPARATUS). [ASTM Designation: D 36-76, AASHTO Designation: T 53-89]SOFTENING POINT: Softening Point of Bitumen. The softening point is defined as the mean of the temperatures at which the bitumen disks soften and sag downwards a distance of 25 mm under the weight of a steel ball.
Earlier, we had discussed the penetration test of bitumen to find out the consistency or hardness, grade the bitumen for the construction work. In this, we are going to test the softening point of bitumen. The softening point test used to determine the melting point in which the bitumen reaches the viscosity (semi-liquid form).
Procedure for Softening Point Test on Bitumen 1. Preparation of test sample Heat the material to a temperature between 75-100° C above its softening point; stir until, it is completely fluid and free from air bubbles and water.

Also, the softening point of viscous bitumen is more. Thus, a bitumen sample with a low penetration value has a high softening point. The road pavement comprises of stone chippings attached together with the help of a binder like bitumen. Bitumen is available in the market in various grades.
