[Highway Engineering #2] Classification of Bitumen | Penetration and viscosity Grade and their test

[@thegossiploverz]

What is the correlation between penetration and viscosity?

[@JustLearnCivil]

Honey is more viscous than water. If you let a needle fall in both of them then needle will be inserted to more depth in water than in honey. It means lesser the viscosity, more is the penetration.

@@JustLearnCivil I am looking for more empirical corellations, thansk for explaining though.
