PREPARATION OF TEST SPECIMEN. One of the most common ways to determine an asphalt’s softening point … - For a given bitumen specimen, the softening point determined in a water bath will be lower than that determined in a glycerin bath. Bitumen is very important component of many construction sites like roads, highways. The softening point of Bituminous material is the temperature at which the material attains a particular degree of softening. As Per IS 1205 1985, IP 58/63 & ASTM D 36. And comparing to the recommended values is that the minimum value of flash point is 175oC for all grades of bitumen. 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. Bitumen extraction test is conducted to determine the percentage of bitumen present in an asphaltic pavement. Why it is Necessary? 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. The unit simultaneously tests two samples for optimal compliance with standard test procedures. I hope this article will help you. The Ductility test has been performed and the ductility value has been calculated as 116 cm. Watch Queue Queue 1203-1958). ... Softening point test for bitumen. QUESTION What is means by softening point of bitumen? 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. 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. This is the reason why the softening point of bitumen is determined. The depth of bitumen in the container is kept at least 15mm more than the expected penetration. Flash and Fire point test is conducted on bitumen to know the safe mixing and application temperature values of particular bitumen grade. Reference Standards IS : 1205-1978-Indian standard methods for testing tar and bituminious materials (Determination of softening point) Equipment & Apparatus Ring and Ball apparatus, Steel balls Brass rings Ball guide Support Thermometer Bath with stirrer Procedure Sample material is … Softening Point Test, continued Because the softening point is needed to establish the uniformity of shipments or sources of supply, it is frequently used to classifying bitumens. The bath temperature not maintained for 15minutes. Bitumen Content 2. The durability, compatibility and resistance from defects like rutting, bleeding, raveling and ageing of flexible asphaltic roads is highly dependent on the amount of the bitumen used for the coating … In no case should the temperature be raised to more than 90 °C above expected softening point for petroleum asphalt (bitumen). Many tests are done to ensure the quality of bitumen. This video is unavailable. ... Heat the bitumen to above its softening point generally 75 o C to 100 o C and stir this softened bitumen thoroughly to remove air bubbles. ii. To determine the Softening point of given bituminous material. Watch Queue Queue. This is the reason why the softening point of bitumen is determined. Discussion: 1-Report the source and type of bitumen. 3. This apparatus is used to determine Softening point of Bitumen. Softening point is the temperature at which the substance attains a particular degree of softening under specified conditions of test. They gradually become softer and less viscous as the temperature rises. Softening point is indicative of the tendency of The softening point is the temperature at which the bitumen attains a particular degree of softening under the specified condition of the test. 2- Report the bath liquid used in the test and quote the mean softening point of your specimen and Comment on the value obtained. Softening point is not a melting point, bituminous material do not melt but instead gradually change from semi solids to liquids on application to heating. 4.Bitumen with higher softening point may be preferred in warmer places. 5.Softening point should be higher than the hottest day temperature, which is anticipated in that area otherwise bitumen may sufficiently soften. Procedure for Penetration Test of Bitumen . 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. Bitumen Extraction test is used to determine the amount of bitumen that is actually used as binding content in asphaltic pavement or asphaltic concrete recently laid at site. ... Report the test temperature and vacuum level with the viscosity test results such as viscosity in poises @ 60 C and 300 mm mercury vacuum. This temperature is to be used in conjunction with the penetration value to obtain the Penetration Index (PI). LAB REPORT HIGHWAY LABORATORY CC302 HIGHWAY ENGINEERING PROGRAMME : DIPLOMA CIVIL State the factors that affect the differences of test result? PRINCIPLE: It is the temperature at which the substance attains a particular degree of softening under specified condition of the test. Softening Point test of bitumen is done to determine the consistency of bitumen. Softening point is not a melting point, bituminous material do not melt but instead gradually change from semi solids to liquids on application to heating. The ASTM D-113 for 60/70 grade the value of Ductility = 100 min. Comment on the value obtained. Sljedeći članak Eyewitness Media Hub. Keywords: softening point, ring and ball, temperature, bitumen, penetration index 1 INTRODUCTION The ring and ball test is for determining the softening point of bitumen, Softening point can be defined as the temperature at which a substance attains a particular degree of softness under specified condition test . Softening Point Of Bitumen Lab Report. Specific Gravity Test. Do not heat samples for more than 30 minutes. The softening point test used to determine the melting point in which the bitumen reaches the viscosity (semi-liquid form). 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. 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. In this, we are going to test the softening point of bitumen. Bitumen is viscous elastic material without sharply defined melting points. The apparatus is shown in Fig. Fig-3 Softening Point Test Setup 4. 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. the softening point. REPORT Report to the nearest 0.5 0 C the mean of the temperature recorded in duplicate as the softening point. LP-16 Softening Point Ring and Ball Apparatus determine the softening point of asphalt, coal tar pitch and other viscoelastic bitumens in the range of 30°—157°C (86°—315°F). 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. This test gives an idea of the temperature at which the bitumen attain certain viscosity. 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.
