... be used to estimate the hydraulic conductivity regardless of the shape of the dissipation curve. Examples of results using the new analysis method are compared with results obtained using laboratory odometer testing. © 2007 Association of Engineering Geologists 2007 Cone Penetration Test...

.... Different clays were also used in the study by van Baalen et al. (2001) , but the samples were prepared by odometer tests using different consolidation loads. In this study, only Proctor samples were used. Proctor samples seem to be the more suitable clay preparation with which to measure adhesion...

...-dimensional consolidation test was carried out on samples with HDPE contents of 0, 5, 10, and 15 percent. The samples were compacted to maximum dry density and optimum moisture content. The compression index (Cc) and swelling index (Cs) were determined form one-dimensional consolidation test using an odometer...

... with 21 profiles in each direction. The orthogonal grid was important to test for azimuthal anisotropy in the GPR response related to the preferred orientation of ice crystal formation. Trace spacing of 5 cm was controlled by a studded odometer wheel. No significant wheel slippage occurred. Repeatability...

...-4318), compaction (ASTM D-698 and D-1557), CBR (ASTM D-1883), swell percentage, swell pressure, and direct shear (ASTM D-3080) tests were performed on all mixes. The Loaded-Swell Method was used for measuring the swell percentage using the standard one-dimensional odometer. For performing...

.... The hydraulic conductivity tests continued for approximately 2 to 8 weeks. After completion of the hydraulic conductivity tests, the clay samples were taken out of the compaction mold. These contaminated clay samples were then carefully cut in a diameter of 75 mm, equal to the size of the odometer apparatus...

... when you are having fun. This has certainly been a fun career for me to meet and interact with interesting professionals from around the world. TLE celebrates its 20th anniversary June 2002. Likewise, my career odometer is about to roll into 20. I completed my graduate studies in June 1982; however...

... interpretation ambiguities associated with indistinct and irregular boundary contrasts at the weathered contact between clay and rock. Nevertheless, field tests indicated some success might be possible, aided to some degree by system optimizations such as higher transmitter impulse power, appropriate stacking...

.... The purpose of this study, therefore, was to show how swelling of organo clays under confining stresses affects their permeability to mixed permeant solutions. Ethanol-water mixtures were used as test solutions for safety considerations and due to the ease with which steady-state conditions could be met...

... a north-south and east-west grid, with a line spacing of 0.5 m. Data were collected using a constant sampling rate instead of an odometer wheel, placing a digital mark every 1 m with the GSSI system. GPR profiles were corrected for time zero drift. After background noise removal, the data sets were...

... properties were populated throughout the volume. Petrophysical distributions were analyzed for distinct rock types using thin sections, mercury injection capillary pressure testing, and whole core analyses (porosity-permeability). These distributions allowed for the population of petrophysical data across...

... ( t ) , (4) where α k is a weighted coefficient for the k th frequency band. In this TVSW process, the number of filters and the width of each band can be flexibly adjusted by tests. We use AGC to enhance the time-domain signals of each frequency band, and the weighted coefficients...

... is performed in a time interval which contains the direct airwaves and ground waves, propagating between transmitting and receiving antennas. To perform the measurements we have selected a natural test site characterized by very strong lateral gradient of the soil electrical properties. To evaluate the effect...

... tests were carried out on statically compacted samples of the mixtures. They were compacted at an optimum water content and a one-dimensional odometer was used to measure the swelling potential and swelling pressure. Swell tests were carried out using the ASTM D 4546 standard test procedure ( Anonymous...

... designed test plot to evaluate the effect on GPR drainage pipe detection caused by the antenna-to-pipe orientation. Antenna orientations perpendicular and parallel to drain lines were tested using 250 MHz antennas. The GPR data were collected under moderately dry and very wet soil conditions. Overall study...

... the laboratory tests, a large number of samples were prepared. All specimens were tested in the one-dimensional Odometer apparatus. Each swell test started by applying a pressure on the sample (placed in a consolidation frame) and allowing it to reach equilibrium deformation. The sample was then fully inundated...

Where steep magnetic gradients were encountered, a ½ -mile station interva l was employed . However, in areas of low magnetic relief a one mile interva l « as felt...

... and centimeter-precise positioning of the antennas at all times are required. Commercially available 3D GPR systems have been developed for detection of concrete rebars and utilities under smooth and flat surfaces. The antennas are equipped with an odometer wheel rolling over the surface. For geologic...

.... For these shallow applications, we use it with low “drive amplitudes” (i.e., 20–40% of the vibrator's possible motion). We have equipped it with a high-precision distance-measuring odometer linked to a small readout screen mounted in the cab, allowing the operator to move quickly and accurately to the next...
