An isolated concrete pavement slab of length $L$ is resting on a frictionless base. The temperature of the top and bottom fibre of the slab are $T_t$ and $T_b$, respectively. Given: the coefficient of thermal expansion $=\alpha$ and the elastic modulus $=E$ ... is calculated as $L \alpha (T_t-T_b)$ $E \alpha (T_t-T_b)$ $\dfrac{E \alpha (T_t-T_b)}{2}\\$ zero

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 $3600$ Poise ductility of bitumen at $27^{\circ}C$ is more than $30$ cm elastic recovery of bitumen at $15^{\circ}C$ is more than $30 \%$
