Uranium in Spring Water North of Grand Canyon Likely Not Related to Nearby Mining Activity
Pigeon Spring had elevated uranium levels in recent samples from 2012-2014 (73-92 micrograms per liter), compared to other perched springs in the same drainage area (2.7–18 micrograms per liter), and was proportionally elevated in samples collected prior to mining operations at the nearby Pigeon Mine. The Grand Canyon National Park in Arizona is a United Nations World Heritage Site, an ...

JPT: Online Digital Rock Portal Launches
Since the 1990s, X-ray computed tomography (CT) has become increasingly popular for its ability to yield big insights from tiny rock samples. But the volume of data produced from CT scanners is anything but tiny, and that makes sharing and storing the files a challenge. In an effort to address this issue and foster collaboration in an area where there is currently very little, researchers at the ...

ASTM D3999 - 11 Standard Test Methods for the Determination of the Modulus and Damping Properties of Soils Using the Cyclic Triaxial Apparatus
The cyclic triaxial modulus and damping test provides parameters that may be considered for use in dynamic, linear and non-linear analytical methods. These test methods are used for the performance evaluation of both natural and engineered structures under dynamic of cyclic loads such as caused by earthquakes, ocean ...

ASTM D4511 - 11 Standard Test Method for Hydraulic Conductivity of Essentially Saturated Peat
Values of hydraulic conductivity determined by this test method may be useful in making rough preliminary estimates of the initial rates of drainage and compression of peat deposits when the only effective stress increase on the deposit is that resulting from a moderate, gradual lowering of the water table. ...

ASTM D806 - 11 Standard Test Method for Cement Content of Hardened Soil-Cement Mixtures
This test method determines cement content in mixtures of cement with soil or aggregate by chemical analysis. It was developed primarily for testing samples for which a significant degree of cement hydration or hardening has taken place. Test Methods D 2901 or D 5982 may be used for determining cement content of freshly mixed soil-cement ...
-
ASTM D5311 - 11 Standard Test Method for Load Controlled Cyclic Triaxial Strength of Soil
Cyclic triaxial strength test results are used for evaluating the ability of a soil to resist the shear stresses induced in a soil mass due to earthquake or other cyclic loading. Cyclic triaxial strength tests may be performed at different values of effective confining pressure on isotropically consolidated ...

ASTM D2726 - 11 Standard Test Method for Bulk Specific Gravity and Density of Non-Absorptive Compacted Bituminous Mixtures
The results obtained from this test method can be used to determine the unit weight of compacted dense bituminous mixtures and in conjunction with Test Method D3203, to obtain percent air voids. These values in turn may be used in determining the relative degree of compaction. Since specific gravity has no units, it must be converted to density in order to do ...

ASTM D3744 / D3744M - 11a Standard Test Method for Aggregate Durability Index
This test method assigns an empirical value to the relative amount, fineness, and character of clay-like material that may be generated in an aggregate when subjected to mechanical degradation. The procedure has been used in limited geographical areas of the United States and the results have been correlated with aggregate performance in various ...

ASTM D4829 - 11 standard test method for expansion index of soils
The expansion index, EI, provides an indication of swelling potential of a compacted soil. The EI test is not used to duplicate any particular field conditions such as soil density, water content, loading, in-place soil structure, or soil water chemistry. However, consistent test conditions are used in preparation of ...
