...T.-K. Li; R. K. Rowe The self-healing of five geosynthetic clay liners (GCLs) with laboratory simulated down-slope erosion defects (quasi-circular holes and linear slits where there is little or no bentonite) upon hydration from Godfrey silty sand subgrade with w_fdn = 16% under...

...T.-K. Li; R. K. Rowe The self-healing of fully penetrating artificial defects (circular holes and rectangular slits) in geosynthetic clay liners (GCLs) on full hydration in deionized water and 10 mM calcium chloride (CaCl₂) solution under 2 kPa overburden stress are compared. Circular...

... to simulate tearing with bentonite loss, or the GCL was punctured with a metal object to simulate damage without bentonite loss. In general, positive results were obtained for the case of damage with bentonite loss: holes up to 3 cm in diameter self-healed with only a slight increase in hydraulic conductivity...
