Abstract
The aim of the work is to present the results of the inspection of the foundations of the overpass and to determine the causes of the defects. This is a particularly relevant task for countries with a large and extensive territory, such as Kazakhstan. This area is located in the centre of Eurasia, where many international routes between Europe and Asian countries have crossed since ancient times until the present day. One of the main international highways is Yekaterinburg - Almaty (2336 km), which is one of the main transport routes between Russia and Kazakhstan. This road was intensively reconstructed in 2013. An overpass was built on the 1114-1137 km section of the Yekaterinburg - Almaty Road. Unfortunately, there was downtime in the construction process. It is therefore proposed to inspect the foundations of the structures, the subgrade soil before continuing the construction. The overpass is located in the village of Zhaltyr, Akmola region.
