Penetration Grades

Penetration grade bitumen is classified based on its hardness or consistency, which is determined by a standardized test. In this test, a needle is allowed to penetrate the bitumen under specified conditions of temperature, time, and load. The depth of penetration, measured in tenths of a millimeter, determines the bitumen's grade. Lower penetration values indicate harder bitumen, while higher penetration values indicate softer bitumen. This classification is critical for ensuring that the bitumen used in a project is suited to the local climate and traffic conditions.
