Swell pressure, matric suction, and matric suction equivalent for undisturbed expansive clays

Canadian Geotechnical Journal, 2015
Methods of computation for soil heave based on an “equivalent” net normal stress path approach often have built-in assumptions regarding the relationship between in situ matric suction, overburden stress, and swell pressure. The term “matric suction equivalent” has been previously defined as the difference between in situ state of stress projected on ...

Matric suction measurements of compacted subgrade soils

Road Materials and Pavement Design, 2015
The mechanical response of compacted subgrade soils is highly influenced by matric suction. This paper proposes a detailed procedure for matric suction determination, using the filter paper technique, in samples compacted in the laboratory using the standard Proctor procedure (ASTM D698-12).

Mini suction probe for matric suction measurements

Canadian Geotechnical Journal, 2002
A modified triaxial apparatus with mini suction probes was fabricated to study the matric suction along the specimen height during unsaturated triaxial testing. Three mini suction probes were placed at 3/4, 1/2, and 1/4 height of the specimen, each at 120° apart in the lateral direction. This paper presents the development of the mini probe for matric
