Abstract
The study of road bases located on subsidence soils is a relevant issue because even though these soils demonstrate considerable strength in a dry state when soaked, they can exhibit sudden subsidence, which can lead to irreparable consequences during the operation of the highway. This article presents the results of laboratory studies of physical and mechanical properties of the soil, the results of field tests of the embankment by plate load test, which in combination provide a completer and more accurate picture of the state of the soil for further design of the highway with minimal costs and losses.
