.... The results reveal strain softening behavior in the interfaces that contain at least one geosynthetic material. For normal stress of 100 kPa, the reduction in shear strength after reaching peak ranged from 11% to 23% for soil-GMB and 24% to 34% for GTX-GMB as temperature varied from 25°C to 80°C. In contrast...

... pattern and transverse-rib thickness have an impact on the interface shear characteristics. The peak and residual interface shear strength of the modified geogrid mesh pattern exceeded that of biaxial geogrids. The average coordination numbers of the modified geogrid mesh pattern were greater than those...

...K. Fan; Q. Pei; L. Liu; Z. Han; W. Zou An experimental program was undertaken to investigate the effects of lignin fibers and freeze-thaw (FT) actions on the shear strength behavior of an expansive soil. Soil specimens were prepared at five lignin fiber contents. Consolidated undrained triaxial...

A series of consolidated undrained (CU) triaxial compression tests were carried out to study the shear strength of reinforced clays with 1% to 5% carpet waste fibres. The results indicated that carpet...
