Title of the article | About definition of temperature field in pavement of steel bridge with orthotropic slab |
Abstract. | This paper represents an analysis of shape and variation of temperature field in selected pavement type of steel bridge with orthotropic slab conducted by using of numerical model. An effort to reveal the relation between pavement temperature variation and circumambient conditions variation and to obtain function describing the temperature curve was made for opportunity of use it in stressed-strain state definition. It was found out that maximum difference between temperatures of asphaltic layer center and free edge is about 5°C when velocity of circumambient temperature changing is about 3-5 °C per 1 hour. Such conditions may lead to occurrence of big temperature stresses and make some contribution to pavement cracks appearance. Whole the temperature curve can be presented as the parabola of the second order. Further if influence of temperature field nonlinearity will not show the great contribution to stresses in asphalt layer then temperature curve may be considered as a straight line. |
