The distribution and orientation of steel fiber are taken into account on the basis of the law of composite material mixture. The formulas of heat transfer coefficient, heat capacity coefficient and thermal deformation coefficient of steel fiber reinforced concrete are given. The finite element method is used to establish the structure of steel fiber concrete pavement structure Finite element equations, the temperature stress of steel fiber reinforced concrete pavement structure was solved. The results show that the temperature stress of steel fiber reinforced concrete pavement structure is non-linear along the thickness direction
