See the penetration grade and viscosity grade of bitumen articles to get more information about them. Flash point test is one of them which is required in many countries. Viscosity test is also reliable in classifying bitumen based on its temperature susceptibility.Īlso, some tests have been introduced to the industry to enhance the safety of bitumen application. Penetration and viscosity tests are also the main basis for classifying various types of bitumen. Also, with help of them, we can predict the hardness or elasticity of bitumen at various temperatures. These testing methods evaluate one of the most important properties of bitumen: its resistance to flow. Tests that measure the consistency of bitumen are penetration, viscosity and ductility tests. We can reduce the risk of cracking and damage on the asphalt by using bitumen tests and checking the quality of the bitumen binder, then choosing the right bitumen for desired conditions. This reduces the quality and life span of the asphalt. It can also be used to classify bitumen by its physical properties.Ĭracks in asphalt can be caused by factors such as traffic and temperature changes. In order to choose proper bitumen for road construction and other industries, bitumen tests are introduced.īitumen tests help us to determine the properties of bitumen and examine its quality before using it, during the application, and after aging. Bitumen is a material with different properties.
