Design specification for highway bridges (limit state design method) does not provide loads for calculating the amount of movement of expansion joints and movable supports. In this study, in order to evaluate the relationship between air temperature and expansion joint deformation, the temperature difference and strain of the clearance of expansion joints were calculated at the maximum temperature in summer and minimum temperature in winter. The expansion temperature ratio (R) values of the probabilities that do not exceed the design values are around 0.993, 1.019, and 1.067 times, respectively, calculated with a 90 %, 95 %, and 99 % normal distribution probability. These methods make it possible to design the amount of clearance change in reliable expansion joints based on probabilistic theory. Expansion temperature ratio was mostly distributed between 0.8 and 1.0. And It was noted that design of movement of expansion joints and movable supports with reliability based on theory of probability could be accomplished.
