ENERGY-SAVING THERMAL STABILIZATION SYSTEM AND ASSESSMENT OF TEMPERATURE LOADINGS OF A BRIDGE DECK PAVEMENT

Abstract

To improve the general traffic safety in conditions of winter ice at traffic interchanges and to extend the overall service life of the roadway, it is proposed to use energy-saving thermal stabilization of a bridge deck pavement by transferring the low-temperature geothermal energy by heat pumps. The practical and computational parts of the pilot plant work are demonstrated and discussed. In order to analyze the need to use additional thermal joints, computer simulation was performed in the LIRA-CAD-2018 software package with subsequent extrapolation to a real bridge span.
