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 $L \alpha (T_tT_b)$ $E \alpha (T_tT_b)$ $\dfrac{E \alpha (T_tT_b)}{2}\\$ zero
