Abstract
In recent years significantly increased the volume of work associated with the bridge replacement canvas on wooden bar in. Besides ending the life of ballastless bridge deck, which have begun to use more than 40 years ago. Also bridge deck on stoves BMP has its drawbacks. So the problem laying layer and currently relevant. To develop new laying layer with high durability, strength, adaptability is important to consider its complex elastic-deformation condition. The article analyzed elastically deformed state and performing the necessary calculations. Given the large number of different types and sizes of stoves ballastless bridge deck and how to load different from them laying layer stoves were selected the most unfavorable transmission of load. Based on the results specified requirements for the necessary strength of laying layer at the time of installation and operation: - rapid entry required strength of 1 MPa at 1 day; - 5 MPa at 28 days.
