we know commonly Bitumen Penetration as penetration grade bitumen. Firstly, It is a standard form of bitumen that we graded based on its hardness level.
Secondly, we determine this grading through a penetration test. And Which we measures the depth a standard needle penetrates the bitumen under specific conditions. In conclusion The penetration value of bitumen is crucial as it indicates its suitability for various road construction applications, for instance.
