Research of simultaneous working of a steel orthotropic plate with road pavement on it at their various parameters

Abstract

Recently, a lot of advanced materials for road pavement has been used on the bridge structures. The stress-strain state of road pavement depends on both stiffness of the orthotropic plate and parameters of the road pavement itself. Using the rational parameters of the orthotropic plates defined at the various spacing of transversal beams on the basis of the strength and stiffness, there was carried out analysis of maximum tensile stresses over the wall of the main beam in the asphaltic concrete pavement due to the car load at the different types of longitudinal ribs. A short service life of the road pavement due to the crack initiation in it is one of the main problems associated with the life duration of bridge structures. Calculation of the superstructure fragment with the road pavement was made in the program complex Zsoil, allowing to simulate the contact between the finite elements.
