$12$: The maximum increase in temperature is expected to be $26C$ after the construction of a $CC$ pavement

If the expansion joint gap is $2\mathrm{.}2m,$ design the spacing between the expansion and contraction joints.

Assume coefficient of thermal expansion as $10{10}^{-6}$per$C,$ unit wt of concrete $=2400k\frac{g}{m^3},$

allowable stress in tension during curing $=0\mathrm{.}8k\frac{g}{c}{m}^2$ and coefficient of friction of the interface $=1\mathrm{.}4.$

i give downvote if your procedure is wrong
