Paper Number: ISRM-IS-2000-593
.... Geotechnical investigations by Douglas Partners and others meant results from 16 test bores and 10 cone penetration tests were available to characterise the site. Hydraulic conductivities (k) of the various strata were estimated from experience in similar conditions and the results of numerous borehole...

ABSTRACT: The suitability of paper mill and construction sludges as landfill cover materials has been examined in view of the scarcity of natural clay sources and reducing waste disposal cost at landfill sites. The results of consolidation, shear strength and hydraulic conductivity tests have...

..., bentonite (B) and kaolinite (K) mixes were investigated as possible replacements. One-dimensional consolidation tests performed on these mixes revealed that B:K mix of 50:50 was similar to pure bentonite from the point of view of hydraulic conductivity (k). Direct hydraulic conductivity tests were conducted...

Existing data demonstrate that asphalt concrete barriers and fluid-applied asphalt layers can provide extremely low hydraulic conductivities (<1x10–11 cm/s). On-going research results show that asphalt may have the robust...

Tests results showed indicated that if the hydrated GCL is after hydration by pure ethanol, the GCL hydraulic conductivity may be increased significantly but not dramatically. Conversely, in case of unhydrated GCL, the hydraulic performance...

.... The boundary conditions are very hard since the support and confining material have a quite high hydraulic conductivity (about 10-4 m/s). Collection of leakage flows is made with lysimeters. These allow the measurement of flow through the defects versus time (figure 1). 1 URGC géotechnique, INSA-Lyon, FRANCE...

.... It was found that the geotextiles tended to be hydrophobic and did not begin wetting until pore suctions were near zero or positive. It was found that the unsaturated hydraulic conductivity of the geotextiles was high when nearly saturated, but that the conductivity decreases rapidly as saturation fell...
