Comparative study on mechanical performance of silty soil and expansive soil below canal structures in cold regions [PDF]
HeliyonSilty soil was widely used as filling soil materials for the replacement of expansive soil in cold regions. This paper presents a straightforward approach for the effects of wetting-drying-freezing-thawing cycles on mechanical behaviors of silty soil and

Engineering Science and Technology, an International Journal, 2020 Structures constructed on expansive soils are experiencing higher upward pressure due to swelling- shrinkage nature of expansive soil. India has 15–20% expansive soil, which causes severe damage to the existing structure, including pavements, dams, multi-
