A ductilometer, also known as a ductility tester or ductility testing machine, is a specialized device used to measure the ductility of materials. This ductility machine assesses how well a material, such as bitumen, can deform under stress without breaking. Often referred to as a ductilimeter or ductility test machine, it provides crucial data for evaluating the flexibility and performance of the material. The ductility test apparatus ensures accurate and reliable measurements, which are essential for maintaining quality standards in construction and material engineering.
