A bitumen sample has been graded as $\text{VG}30$ as per $\text{IS:}73-2013$. The $'30'$ in the grade means that penetration of bitumen at $25^{\circ}C$ is between $20$ and $40$ viscosity of bitumen at $60^{\circ}C$ is between $2400$ and $3600$ ... of bitumen at $27^{\circ}C$ is more than $30$ cm elastic recovery of bitumen at $15^{\circ}C$ is more than $30 \%$
