Watch Queue Queue Bitumen Content 2. Loss on heating and a rolling thin-film oven are used for testing bitumen, flash and fire point are measured with the Cleveland Flash Cup Apparatus, and the Ring and Ball test enables the measurement of the softening point. CONCLUSION From the laboratory test we did on the bitumen in Flash and Fire Point, the result we obtained is, Flash temperature is 256oC, and the Fire Point temperature is 270oC. Softening Point Of Bitumen Soften the material to a pouring consistency at a temperature not more than 60°C for tars and 90°C for bitumen over the rough softening point and blend it completely until it is homogeneous and is free from air pockets and water. 5.Softening point should be higher than the hottest day temperature, which is anticipated in that area otherwise bitumen may sufficiently soften. Softening point is the temperature at which the substance attains a particular degree of softening under specified conditions of test. Some of these are given below :-1. This is the reason why the softening point of bitumen is determined. In this laboratory, the tests were performed with a view to determine the softening point of a sample of bitumen (2) determine the penetration value of three samples of StudentShare Our website is a unique platform where students can share their papers in a matter of giving an example of the work to be done. Softening point is indicative of the tendency of Why it is Necessary? To determine the Softening point of given bituminous material. 1203-1958). Steel balls are placed on top of bitumen specimen disks in test rings in a bath. Penetration of Bitumen 4. Softening Point test of bitumen is done to determine the consistency of bitumen. This is the reason why the softening point of bitumen is determined. Temperature was not maintained in the lab so the value may differ at 25 o C as we performed at the Lab temperature. PREPARATION OF TEST SPECIMEN. Do not heat samples for more than 30 minutes. The softening point is reported as the The ASTM D-113 for 60/70 grade the value of Ductility = 100 min. They gradually become softer and less viscous as the temperature rises. The apparatus is shown in Fig. The softening point is the temperature at which the bitumen attains a particular degree of softening under the specified condition of the test. ... Softening point test for bitumen. (b) Report the bath liquid used in the test and quote the mean softening point of your specimen. 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. 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. Also Read: Softening Test Procedure of Bitumen. QUESTION What is means by softening point of bitumen? Water is used for bitumen with a softening point of 80°C or below and glycerin is used for softening points greater than 80°C. Earlier, we had discussed the penetration test of bitumen to find out the consistency or hardness, grade the bitumen for the construction work. This video is unavailable. ii. The unit simultaneously tests two samples for optimal compliance with standard test procedures. The Ductility test has been performed and the ductility value has been calculated as 116 cm. The softening point test used to determine the melting point in which the bitumen reaches the viscosity (semi-liquid form). The softening point of Bituminous material is the temperature at which the material attains a particular degree of softening. bitumen softens and sags down about 25mm below the weight of steel ball. And comparing to the recommended values is that the minimum value of flash point is 175oC for all grades of bitumen. This test is important because various pavement properties such as durability, compatibility, resistance to various defects and failure such as ravelling, rutting, bleeding etc depend upon the content of bitumen present as the binder for the aggregates. 5 (5) Objective:- 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 … Softening Point Test of Bitumen As Per IS: 1205-1978 Read More » Summary of Test Method 3.1 Two horizontal disks of bitumen, cast in shouldered brass rings, are heated at a controlled rate in a liquid bath while each supports a steel ball. Watch Queue Queue. PRINCIPLE: It is the temperature at which the substance attains a particular degree of softening under specified condition of the test. I hope this article will help you. Softening Point Of Bitumen Lab Report. Fig-3 shows Softening Point test setup. It is that temperature at which a sample of bituminous material loaded by a 9.5mm dia steel ball, drops a specified distance when heated under specified conditions. Many tests are done to ensure the quality of bitumen. State the factors that affect the differences of test result? 4.Bitumen with higher softening point may be preferred in warmer places. One of the most common ways to determine an asphalt’s softening point … This temperature is to be used in conjunction with the penetration value to obtain the Penetration Index (PI). D 3461 Test Method for Softening Point of Asphalt and Pitch (Mettler Cup-and-Ball Method)5 E 1 Specification for ASTM Thermometers6 3. Fig-3 Softening Point Test Setup 4. The bath temperature not maintained for 15minutes. The bitumen is softened to a pouring consistency, stirred well, and poured into the test containers.
