EVALUATION OF EXPANSIVENESS OF PLIOCENE CLAYS FROM DOBRE AREA

Abstract. In this paper the evaluation of expansiveness of Pliocene clays from Dobre area was presented. It has been stated that these clays are in semi-solid state and are characterized by a high content of clay fraction with Ca-beidellit as a dominant clay mineral. Although the tested clays are characterized by high and very high potential expansiveness PE, in natural conditions they shall not constitute a threat because of the high degree of saturation and low values of swelling pressure.
