Determination of ductility of bitumen

WebRecommended Penetration Value of Bitumen. Penetration test is a commonly adopted test on bitumen to grade the material in terms of its hardness. A 80/100 grade bitumen indicates that its penetration value … WebFor the determination of ductility and brittleness tension tests and bending tests are used. The ductility and brittleness depend on the special cohesive characteristics of the sample. The behavior depends on the temperature. For example, bitumen shows a brittle fracture at low temperatures.
