Microstructure and Mechanical Properties of Expansive Clay under Drying–Wetting Cycle

open access: yesApplied Sciences, 2023
Expansive clay is one of the most widely distributed soils in the world. Due to its rich content of strongly hydrophilic minerals—such as montmorillonite—expansive clay exhibits substantial swelling and shrinkage properties, and overconsolidation.

Dynamic strength of fly ash-modified loess subgrade under influences of drying-wetting cycle

open access: yesYantu gongcheng xuebao, 2020
The traffic load and the drying-wetting cycle have an important influence on the strength characteristics and stability of fly ash-modified loess subgrade. To illustrate the influences of drying-wetting cycle on the strength of the fly ash-modified loess,
