Softening point test Softening point denotes the temperature at which the bitumen attains a particular degree of softening under the specifications of test. 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 glycerin at a given temperature.

Penetration value test on bitumen is a measure of hardness or consistency of bituminous material. A 80/100 grade bitumen indicates that its penetration value lies between 80 & 100. Penetration value is the vertical distance traversed or penetrated by the point of a standard needle into the bituminous material under specific conditions of load, time and temperature.

The softening point of bitumen or tar is the temperature at which the substance attains particular degree of softening. As per IS: 334-1982, ASTM E28-67 or ASTM D36 or ASTM D6493 – 11, it is the temperature in ºC at which a standard ball passes through a sample of bitumen in a mould and falls through a height of 2.5 cm, when heated under water or glycerin at specified conditions of test.

The softening point is defined as the temperature at which the resin flows under a given load on heating. Several standard methods have been proposed to determine the softening point of resins. (1) Ring and Ball method (R&B) — ASTM D 3461-76, DIN ISO 4625. This method is the most frequently used to determine the softening point of resins.

The Softening Point Test the Softening Point Test° involves preparing discs of bitumen and determining the temperature at which these discs are unable to support a standard metal ball (Fig. 2.8). At the softening point, all unmodified bitumens have approximately equal penetration (800 dmm) and viscosity (1200 Pas).

11-07-2019· Softening point denotes the temperature at which the bitumen soften.In this video,we will discuss how to determine the test as per IS 1205.

(e) Calculate the PI and comment on the value obtained. (Make sure the penetration and softening point values are obtained from the same batch of bitumen). (f) Compile and compare results with other groups. REFERENCES 1. ASTM (1998). ASTM D5-97 Standard test method for penetration of bituminous materials. 1998 Annual Book of ASTM Standards, Volume

Penetration value test on bitumen is a measure of hardness or consistency of bituminous material. Penetration value is the vertical distance traversed or penetrated by the point of a standard needle into the bituminous material under specific conditions of load, time and temperature.

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), USP glycerin (above 80 to 157°C), or ethylene glycol (30 to 110°C). 1.2 The values stated in SI units are to be regarded as the standard.

Standard Test Method for Softening Point of Bitumen (Ring-and-Ball Apparatus)1 This standard is issued under the fixed designation D 36; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.

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.

05-04-2020· Infiltration Value of Bitumen -Determination for Roadway Construction A Student may be granted an Honours classification on a parchment if semester and also advancing quality point standard of 3.7 is achieved on the initial effort of courses needed towards college graduation of major.

Softening Point of Bitumen. 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).

The softening point of bitumen or tar is the temperature at which the substance attains particular degree of softening. As per IS: 334-1982, ASTM E28-67 or ASTM D36 or ASTM D6493 - 11, it is the temperature in ºC at which a standard ball passes through a sample of bitumen …

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.

So the softening point test is conducted to ensure that the bitumen can withstand the hot weather conditions. According to the requirement of the usage, the bitumen can be classified and used for pavement construction. Objective. To determine the softening point of the bitumen specimen as per the IS code 1205. Apparatus Required
