  • A Modified California Bearing Ratio Test for Granular Materials

    It is known that laboratory and field tests, under saturation conditions, yield different California Bearing Ratio (CBR) test values for granular material. This is due primarily to the higher laboratory strength of the specimen confined in a rigid cylinder. A laboratory procedure is outlined by which specimens are subjected to controlled lateral pressure. A formula is proposed for determining ...

  • Uniaxial Tension Tests on Cement-Stabilized Granular Materials

    This paper presents details of tests to evaluate the suitability of a double scissor friction grip system, initially developed for conventional concrete, for determining uniaxial tensile strength of cement-stabilized granular materials suitable for use in roadbase construction. The system is examined in terms of the variability of the results, the significance of fracture location, and the ...

  • Application of the American Society of Testing and Materials’ (ASTM) New Skimmer Test Protocol

    Abstract The American Society of Testing and Materials (ASTM) subcommittee on skimmers recently adopted a standard methodology for measuring the nameplate capacity for a given skimmer system. Current industry practice allows manufacturers to label skimmers with a nameplate capacity that may bear little relationship to the ability of the skimmer, as a system, to recover oil. Manufacturers ...

  • Indirect Tension Tests on Rock—Analytical/Numerical Correction for Material Bimodularity

    Many rocks have different deformational properties when loaded in tension and in compression. This property is referred to as bimodularity. The influence of bimodularity on four of the most commonly utilized indirect tension testing methods for measuring the tensile strength of rock is investigated analytically and numerically in this paper. These indirect tension methods include the three-point ...

  • Deformability of Rock-Like Materials Using a Sharp Cone Test

    This paper presents a new idea for a field testing technique, the sharp cone test (SCT), for the determination of certain deformability parameters of rock-like materials. The test is described, and the theoretical background required for its interpretation is given. The influence of the interpretation model hypotheses is assessed by a finite element analysis. The results of sharp cone tests in ...

  • Material flow accounting of Spain

    Material throughput is a means of measuring the so-called social metabolism, or physical dimensions of a society's consumption, and can be taken as an indirect and approximate indicator of sustainability. Material flow accounting can be used to test the dematerialisation hypothesis, the idea that technological progress causes a decrease in total material used (strong dematerialisation) or ...

  • When is material ‘spent?

    The definition of solid waste has been frequently tested in the courts. A recent court decision provides new guidance on this meaning, and might have made things tougher for well-meaning enterprises. The definition of a hazardous waste under the Resource Conservation and Recovery Act (RCRA) is nearly impossible to understand. A recent court ruling has not helped eliminate confusion and, some ...
