ROAD  EMBANKMENT  STABILITY  ENSURING  AT  WATERLOGGING

Considerations on geotechnical monitoring of damages accumulated during the road embankment service are presented in this paper. Experimental and theoretical prerequisites are shown in relation to reduction of clay soil filtration. Numerical modeling of water filtered through the road embankment equipped with an impervious blanket having variablepermeabilityandconfiguration is discussed herein. The stability of embankment is achieved by an impervious blanket using soil alkalization control method.

Keywords: waterlogging; road embankment; geotechnical monitoring; impervious blanket;soil alkalization control.
