The problems of calculation and forecasting of cement-concrete pavement thermostressed state taking into account cement exothermicity at the early stage (165 hours) of cement hardening are considered and solved. Heat-evolution at cement hydration was estimated by means of the method of thermokynetic analysis with the help of differential microcalorimeter. Calculation of thermal fields and tensile stresses arising from the non-uniformity of temperature over the thickness of cement-concrete slab was performed with the help ot package of programs "Mathematica 3".
