  • Evaluation of the environmental conditioning system as a water sensitivity test for asphalt concrete mixtures

    Creator:
    Allen, Wendy L.
    Abstract:
    The Environmental Conditioning System (ECS) was designed to evaluate the water sensitivity of asphalt concrete mixtures. The ECS subjects asphalt concrete specimens to a series of conditioning cycles including water flow, elevated and/or lowered temperature, and repeated axial loading. The purpose of this research was to: (1) evaluate the ECS...

  • Overland flow treatment of swine lagoon effluent

    Creator:
    Boda, Joseph Owen
    Abstract:
    Effluent from an anaerobic swine manure lagoon was applied at the upper end of six, 100 feet (30.5 m) long by 3 feet (0.9m) wide, grass-covered plots which sloped about 3 percent. The objectives were to measure concentration attenuation and mass reduction of potential pollutants in the wastewater as the...

  • Influence of expansive soils on structures in the Eugene area

    Creator:
    Bonell, John Alexander
    Abstract:
    Expansive soils in Eugene, Oregon present a problem to residents, consultants, contractors, and the city government. During the years 1977 to 1979, the nature and extent of the problem was identified, including an outline of the local occurrence of expansive soils and possible engineering solutions to the most often encountered...

  • Disposal of sandy pipeline dredge spoils by end dumping

    Creator:
    Pyles, Marvin Russell
    Abstract:
    Channel maintenance operations in the rivers and harbors of the United States annually require the disposal of over 320 million cubic meters of dredge spoils. As the availability of suitable land sites diminishes, open water disposal presents an attractive yet controversial alternative method. For open water disposal to be acceptable,...

  • Experiments on cable strumming and flow induced drag

    Creator:
    Barnes, Bert Lee
    Abstract:
    Short non-flexible elements of cable were driven harmonically in water while constrained by springs. The cable elements were observed to oscillate at approximately the Strouhal vortex shedding frequency. Damped resonance occurred near the point where the natural frequency and the Strouhal vertex shedding frequency were equal. Transverse oscillation amplitudes greater...

  • Demonstration of a permeable barrier technology for the in-situ bioremediation of pentachlorophenol contaminated groundwater

    Creator:
    Cole, Jason David
    Abstract:
    A pilot scale demonstration of a biological permeable barrier was conducted in a pentachlorophenol-contaminated aquifer at a wood preserving facility. A permeable reactor was constructed to fit within a large diameter well. Arranged in series, a cylindrical reactor 24" x 36" (0.61 x 0.91m) (diameter x height) was partitioned to...

  • Penetration resistance predictions for driven piling

    Creator:
    Hansen, Lawrence A.
    Abstract:
    This paper presents a method of predicting penetration resistance for driven piles, using known driving records for driving the same type piling in similar subsurface conditions. As known driving records are not always available to the analyst, a method was also investigated using soil data only. The analytical tools employed...

  • Bioremediation of low-permeability, pentachlorophenol-contaminated soil by laboratory and full-scale processes

    Creator:
    Havighorst, Mark B.
    Abstract:
    Ex-situ bioremediation of saturated soil contaminated with pentachlorophenol and 2,3,5,6-TeCP is commonly accomplished by landfarming or by treatment in a bioreactor. Treating saturated, low-permeability soils in bioreactors, without pre-treatment requires a reactor capable of promoting anaerobic and/or aerobic removal of chlorophenols without transferring these contaminants to the aqueous phase. A...

  • Behavior of cellular bulkheads in deep sands

    Creator:
    Maitland, James Keith
    Abstract:
    Large-scale experiments on circular model cell bulkheads were conducted to define the distribution of hoop stresses, deflections of the cells, distortion of the cell fill, ultimate overturning resistance, and the critical mode of failure. The embedment depth of the model cells was varied to investigate the effect of embedment on...

  • Properties of marginal aggregates treated with asphalt emulsion

    Creator:
    Evans, Gary L.
    Abstract:
    The purpose of this report is to address the problem of supplying construction aggregates to Oregon's coastal areas that are currently, or will in the near future, be deficient of good quality materials. This is done primarily by studying methods of utilizing marginal aggregates that are abundantly available in the...
