Webductility as being unobtainable under the conditions of the test. 7. Precision 7.1 Criteria for judging the acceptability of ductility test results at 25°C obtained by this test method are shown in Fig. 2. NOTE 2—The precision statement for ductility, as presented in Fig. 2, is based on tests performed on asphalt cements. The precision of ... WebThe bitumen is a composition of two factors (Structure of Bitumen) asphaltenes miscelles and maltenes. In bitumen sol, the asphaltenes miscelles are dispersed in maltenes continuum. As the asphaltenes content reduces, the viscosity of bitumen also decreases. Aggregation is the factor that governs the viscosity of gel type bitumen. Gel type ...
WebJan 23, 2024 · This article has used lignin additive to improve the bitumen properties as well as the asphalt mixture performance. Therefore, Lignin added to the bitumen 60/70 in various weight percentage (3, 6, 9 and 12 percent). Then, its effect on various properties of bitumen, including penetration grade, softening point, ductility, viscosity, weight loss … WebDuctility is the property of bitumen that permits it to undergo great deformation or elongation. Ductility is defined as the distance in cm, to which a standard sample or briquette of the material will be elongated without breaking. Dimension of the briquette thus formed is exactly 1 cm square. ... Determination of Loss on heating: IS:1212-1978:
