... Soil as a corrosive environment is probably of greater complexity than any other environment. The corrosion process of buried metal structures is extremely variable and can range from rapid to negligible. With background knowledge of the principal soil characteristics and their influence...

... When designing building foundations, infrastructure, or operations for natural resource retrieval in cold regions, mechanical properties of frozen soils need to be known in order to avoid sudden bearing capacity failures, excessive creep settlements, and slope failures. Several methods exist...

... is a three-point impact compaction test based on standard impact compaction energy level, and is performed on an adjusted wet density basis thus alleviating the need for water content determinations. Each soil sample from the in-place density test is tested using the Rapid Method to assure accurate...

... This paper describes a comparative study of the three most commonly used field density tests: sand-cone, nuclear, and drive-cylinder. In order to evaluate the range of variability of these tests, a large-scale soil compaction apparatus was constructed so that soil could be compacted to a known...

... The Interim Superfund Method for the Determination of Releasable Asbestos in Soils and Bulk Materials [ 1 ] provides asbestos measurements that can be related directly to risk. Results from a pilot study indicate that target sensitivities of 5 × 10 7 total asb s/g and 3 × 10 6 long asb s/g...

... available. Food-chain analysis has frequently been applied to the analysis of exposure to BCCs identified as chemicals of potential ecological concern (COPECs) in the ecological risk assessment process. Here, designed studies focused on wetland food-chains such as “hydric soil → soil macroinvertebrate...

... Soil-cement slurry used in buried pipe installations has become an increasing popular choice for contractors. Flexible pipe, including PVC and RPM, as well as rigid pipe are being installed using this technique. The ingredients of the soil-cement can vary, but typically is a combination of soil...

... A laminar box has been constructed at Rensselaer Polytechnic Institute to permit accurate dynamic centrifuge testing of geotechnical and soil-structure models subjected to horizontal one-dimensional earthquake excitation at the base of a soil deposit. The container is designed for dry...

... The MetalTrace method, which consists of an anion-exchange separation coupled with a spectrophotometric quantification, was used to determine lead and cadmium in sulfuric acid-hydrogen peroxide digests of soils and sludges and hydrobromic acid extracts of soils. Cadmium only was determined...

... In this work, two areas of application of the GEODUR additive in cement stabilization of waste materials have been investigated: stabilization of radioactive contaminated soil and stabilization of municipal solid waste incinerator ash. Preliminary experimental work on a clayey soil contaminated...

... A recently developed bioassay protocol was used to characterize seven different soil types and Promix BX. The green alga Selenastrum capricornutum was used as the test organism. A ruggedness test which altered seven variables was conducted to identify procedural stipulations that should...

... from four highway reconstruction sites were sampled to determine the maximum weight loss from the most corroded area of each pipe. In-situ and laboratory soil resistivities were determined in or adjacent to each pipe trench, along with soil pH and soluble salts including sulfates. Corrosive weight loss...

... The presence of total organic halides (TOX) in soils and sediments is a good indicator that the soil, and possibly the underlying aquifiers, are contaminated. Since many halogenated organics are highly toxic to human health with some being carcinogenic, and naturally occurring organic halides...

... Galvanic corrosion current measurements carried out on stressed Type 301 stainless steel coupled to zinc at six underground test sites over a period of four years indicate that the galvanic current is controlled by soil resistivity or oxygen availability in the soil. In well aerated soils...
