Investigation of changes in the physical properties of the sandy soil in geotechnical control of the road embankment

Abstract

The aim of this work is to determine the effect of “temperature-precipitation” climate parameters on the physical properties of sandy soil of an embankment during the construction period. The object of this study is sand from a quarry and the upper layer of the road embankment before and after the climatic effect during the “autumn-winter-spring” period. The results of this study revealed changes in sand gradation, coefficient of permeability and void ratio of a sandy soil after the influence of “temperature-precipitation” climate parameters during a short time period. The results of this study can be used for geotechnical control of construction process.
