Bitumen Penetration Grade

 

Penetration of bitumen refers to a test used to determine the consistency or hardness of bitumen. It’s a key quality indicator in material selection, it helps in assessing the hardness or softness of bitumen, which directly impacts its performance under different temperatures and load conditions. The penetration value is crucial in determining how suitable the bitumen is for different types of pavements or road surfaces, depending on climate and traffic.

 

 

 

Higher penetration value: Indicates softer bitumen.

 

 

Lower penetration value: Indicates harder bitumen.
