PRINCIPLE: The ductility of a bituminous…. Ductility is the property of Bitumen that permits it to undergo great deformation or elongation. Humboldt’s ductility testing machines measure the distance of elongation before reaching the breaking point of a sample being pulled apart at a specific speed and temperature. We know that the ductility of a material is the ability of that material to undergo plastic deformation (permanent deformation) before the rupture of that material. Ductility is used as a performance-based specification criterion for bitumen in product specification standards.

The briquette mould should not have a crack at any side, The base plate of the briquette mould on which the sample is to be laid should be completely flat, While filling the mould with the sample, care should be exercised so that the parts of the briquette are not displaced, Care should be taken that no air bubble is entrapped within the sample while preparing the mould, The temperature of the water bath should not exceed 27 °C, The pull rate of the ductility testing machine should not exceed 50 mm/min. The result of this test will show the amount of elasticity and tensile strength of bitumen. The Man Behind CivilJungle. The mold side has been removed, the clamps hooked on the machine and the pointer set to zero or the initial reading noted. The Internal tank is made of stainless steel. Measure the distance between the clips at the time of rupture of the specimen. The consistency of the sample is determined by measuring the distance in one-tenth of a millimeter the distance by which the penetrating needle penetrates in the sample under certain loading 100 g at 25 c for 5 seconds, penetrations less than 2 … This section lists the equipment required for bitumen testing, including machines to study the rheological properties of bitumen as well as the features of bituminous emulsion. Take the bitumen sample in a beaker and heat it to a temperature of 75-100°C- above its approximate softening point.

The practical works on the below principle: When a standard pulling force is applied to a bitumen specimen at a specific speed and specific temperature, the specimen will elongate before breaking. The ductility test has been performed to determine the elongation length of bitumen at a specific temperature. The related standards are EN 13589, EN 13703 and AASHTO T300. The average of the ductility values to the nearest whole value obtained from the three moulds is the ductility value of the given bitumen specimen. bitumen & asphalt test equipments Wholesaler of a wide range of products which include semi automatic ring & ball apparatus, ductility testing machine, benkalman beam test apparatus, pavement core drilling machine, motorized centrifuge bitumen extractor and bitumen cone penetrometer. This distance in cms gives the bitumen ductility value. Design by: Civil Engineer - CementConcrete.org. The clips are now separated horizontally at a rate of 50 mm per minute and the distance to the point where the line breaks are observed. 3. The bitumen sample is heated in a beaker at 75-100 °C- above, the softening point of bitumen till it is completely melted into a fluid, 2. The water depth above and below the specimen should be at least 25 mm. Structural loads in buildings produce various types of action such as deformations, stresses, or displacements. The ductility test on bitumen is  use to measure following: Ductility of bitumen is the distance by which it elongates in cm before it breaks when kept in standard briquettes at standard conditions. For the purpose of flexible pavement design, it is necessary for the binders to form a thin ductile film around the aggregates in order to improve the physical interlocking of the aggregates. 7 Tips to Build a Prime Commercial Building, Explosion-Proof Construction: Materials and Procedures. This method, under European standard EN 1427, serves to test the behaviour of bitumen at elevated service temperatures. The temperature is determined at which a layer of bitumen, in a brass ring, experiences a certain deformation under the weight of a steel ball as the temperature rises. Penetration test. As per I.S. A minimum of 5 cm value is required for a bitumen of grade 45 and above. I started this site to spread knowledge about Civil/Mechanical/Electrical Engineering. Found inside – Page 598The ductility test is then made on the mixture of asphalt and flux so prepared . Different asphalts vary considerably in purity and character of bitumen . In this ductility test of bitumen, the amount by which the bitumen will stretch at a temperature below the softening point is determined. ); (2) thread formation (ductility > 1 cm.). The ductility test of bitumen specimen is dependent on the grade of the bitumen. The ductility is expressed as the distance in centimeters to which a standard briquette of bitumen can be stretched before the thread breaks. The ductility of a bituminous material is measured by the distance in cm that it elongates before breaking when a standard briquette sample of the material is separated at a specified speed and temperature. The ductility test of bitumen is one of the main tests you need to do when building the road. 2.
