  • Determination of structural layer properties of aggregate and asphalt surfaced roads

    Creator:
    Rwebangira, T.
    Abstract:
    This study involved the determination of the structural layer properties of aggregate and asphalt surfaced pavements for use in the evaluation of pavement load carrying capacity and the seasonal effects of moisture. This was achieved by the use of Nondestructive Testing Methods (NDT) and backcalculation techniques. Pavement surface deflection measurements...

  • Ocean wave-soil-caisson interaction

    Creator:
    Tsai, Yau-tang
    Abstract:
    Caissons on permeable seabeds have been designed and constructed for a variety of needs in coastal and offshore engineering. An evaluation of the adequacy of the foundation beneath the structure is required for an economic and safe design. To address this requirement, a two-dimensional analytical model of the foundation response...

  • The control and fate of enteric bacteria in the environment with particular emphasis on the factors influencing fecal indicator survival in waste storage facilities

    Creator:
    Crane, Stuart R.
    Abstract:
    The indiscriminate release of fecal bacteria to the environment can present a public health hazard when pathogenic species gain access to drinking and recreational water sources. The extent of bacterial contamination of surface and ground waters associated with animal production units and waste application areas seems largely dependent on the...

  • Evaluation of mix ingredients on the performance of rubber-modified asphalt mixtures

    Creator:
    Takallou, Hossein B.
    Abstract:
    Rubber-modified asphalt pavements have been used in Sweden and the United States since the 1970's. In these applications ground recycled tire particles (0.25 inch minus) are added to a gap-graded aggregate and then mixed with hot asphalt cement. The benefits of adding rubber to the mix include increased skid resistance...

  • Behavior of a compliant wave-current barrier

    Creator:
    Kerper, Dale R.
    Abstract:
    This study includes an analytical solution to the wave-current barrier interaction problem and large scale experiments to validate the theory. The boundary value problem is solved mathematically by characterizing the flow field and barrier motion separately, then coupling the relationships with the appropriate kinematic and dynamic boundary conditions. The flow...

  • Chemical characterization of asphalt cements using chromatographic techniques : relation to rheological properties and field performance

    Creator:
    Thenoux, Guillermo
    Abstract:
    This dissertation presents the findings of a literature review and information regarding selection, implementation and development of a chemical composition procedure for asphalt cements. The chemical composition analysis selected was the Corbett-Swarbrick procedure standarized as ASTM D4124. The procedure is a selective adsorption / desorption (solid / liquid) chromatography which...

  • Irregular points in wavemaker boundary value problem

    Creator:
    Tanaka, Yoshihiro
    Abstract:
    A global solution is presented that accurately accounts for the singular behavior at all irregular points. The linearized boundary value problem in a semi-infinite strip in the physical plane is transformed into a smooth unit disk by two successive conformal mappings. The global solution results from a Fredholm integral equation...

  • Modeling solute transport by centrifugation

    Creator:
    Celorie, Jay A.
    Abstract:
    Measurement of physical and chemical solute transport properties of a soil/waste system is necessary to predict pollutant migration in soils. The adsorption component of solute transport is most often determined in the laboratory by performing column studies and batch equilibrium tests. Both of these methods suffer from disadvantages. Batch equilibrium...

  • The development of a gas-permeable-membrane-supported (GPMS) biofilm reactor for the combined anaerobic/aerobic treatment of polychlorinated biphenyls

    Creator:
    Polonsky, Jon D.
    Abstract:
    A continuous flow, gas-permeable-membrane-supported (GPMS) biofilm reactor was developed to facilitate the treatment of polychlorinated biphenyls (PCBs). The GPMS biofilm reactor consisted of a cylindrical glass vessel made up of three compartments: the gas, liquid and headspace compartments. A gas-permeable membrane separated the bottom gas compartment from the liquid compartment....
