Bitumen is a material with different properties. Tests on bitumen are done to check bitumen quality and choose proper bitumen for road construction and other industries. Bitumen tests help us to determine the properties of bitumen and examine its quality before using it, during the application, and after aging. It can also be used to classify bitumen by its physical properties. Keep reading this article to get more information about bitumen test, their procedure and importance.
Tests that measure the consistency of bitumen are penetration, viscosity and ductility tests. These testing methods evaluate one of the most important properties of bitumen: its resistance to flow. Also, with help of them, we can predict the hardness or elasticity of bitumen at various temperatures.
Penetration and viscosity tests are also the main basis for classifying various types of bitumen. Viscosity test is also reliable in classifying bitumen based on its temperature susceptibility. Also, some tests have been introduced to the industry to enhance the safety of bitumen application. Flash point test is one of them which is required in many countries.
