Expansion Joint With Elastic Compensator

Abstract

Purpose. The purpose of given research is the development of the expansion joint for city highway and railway bridges that is both easily manufactured and cheap. Methodology. To reach the set goal available materials and specific design with elastic compensator were used. Findings. Expansion joints with elastic compensator that are applicable for the city bridges with limited span length and for railway bridges with ballasted bridge deck were proposed. Originality. Proposed design of the expansion joint uses the arch effect of the elastic compensator itself. Practical value. Proposed design has a low cost, is easy in the installation and easy in the operation. In the conditions of economic crisis and current state of the large number of defective expansion joints on the bridges of the county, the possibility arises to fix these flaws in quite a low cost.
