16. Hydraulic Performance of Compacted Clay Liners Under Simulated Daily Thermal Cycles (New Paper)
•The research studies the effect of thermal cycles on CCLs’ permeability and shrinkage.
•The daily thermal cycles induced shrinkage and hence permeability increased.
•The higher the CCL plasticity the larger the shrinkage magnitude.
•Higher CCL plasticity provides better self-healing and hydraulic performance.
•The geomembrane cover reduces the effect of thermal and wet/dry cycles on CCLs.

17. Frictional Behaviour of Three Critical Geosynthetic Interfaces (New Paper)
The shear interaction mechanisms of three critical geosynthetic interfaces (geotextile/geomembrane; drainage geocomposite/geomembrane and soil/geomembrane) typically was studied. For geotextile/geomembrane and drainage geocomposite/geomembrane interfaces, the higher the asperity height, the higher the interface shear strength. Whereas for soil/geomembrane interfaces, the higher the soil shear strength, the higher the interface shear strength. The drainage geocomposite/geomembrane interface showed the lowest friction angles, followed by the geotextile/geomembrane and the soil/geomembrane interfaces.
