Maintenance particulars of bridges and pipe culverts on major traffic arteries located in the North climatic zone of the Asia Pacific region

Abstract

The research data of the technical state of bridges that are built and maintained in the North climatic zone of the APR is set forth in the article. The impact of climatic, environmental, and geotechnical aspects, as well as engineering and maintenance procedures on the technical state of artificial structures is analyzed. To ensure health and serviceability of artificial structures, monitoring of their state and temperature survey of permafrost subgrade soils along with predicted heat engineering calculations during maintenance term are to be carried out.
