WebIntroduction A test for One of the key tests carried out during the construction of roads is the bitumen's ductility. The ability of a material to undergo plastic deformation (permanent deformation) prior to rupturing (breaking) is referred to as ductility. Bituminous materials used in pavement construction should have sufficient ductility in order to prevent cracks … WebMar 28, 2024 · The bitumen grade is specified in terms of penetration value. Higher penetration implies softer grade. Ductility is the property of bitumen that permits it to undergo great deformation or elongation. Use of ductility test is to measure the adhesive property of bitumen and its ability to stretch.
