    The penetration value is 1/10th of the bitumen sample grade.
    The penetration value of 80 means the needle of the penetration test apparatus penetrates the bitumen sample by 80/10= 8 mm

    °C is the distance in tenths of a millimeter that a standard needle will penetrate the sample under specific conditions. This value is used to classify bitumen into different grades based on its hardness and viscosity. The higher the penetration value, the softer the bitumen, and the lower the penetration value, the harder the bitumen. The standard penetration test is performed according to ASTM D5 or AASHTO T49.
