  • Evaluation of alternate surfacing systems for temporary and intermittent use roads

    Creator:
    Takallou, Mojtaba B.
    Abstract:
    The purpose of this study was to provide the USDA-Forest Service, Bureau of Land Management (BLM), and other agencies or industries that may deal with temporary and intermittent use roads with the necessary background information for the identification, economic evaluation, and selection of the alternate surfacing systems and to determine...

  • The performance of drivers with physical limitations at T-intersections

    Creator:
    Hunter-Zaworski, Katharine M.
    Abstract:
    The research examines the effect of restricted head and neck movement on driving performance as measured by decision time at T-intersections. The traffic safety and human factors literature was reviewed, and very little was found concerning drivers with physical limitations. T-intersections were selected for study because most accidents involving drivers...

  • FATE group decision support system in transportation decision making

    Creator:
    Taekratok, Thaweesak
    Abstract:
    Two interesting challenges have been created in the traditional transportation planning process through recent adoption of more interactive roles by Federal, State and local transportation agencies and of those representing the communities being impacted by proposed transportation projects. First, the decision-making groups that formerly included solely transportation and related professionals...

  • Development of a mechanistic overlay design procedure for flexible pavements

    Creator:
    Zhou, Haiping
    Abstract:
    This dissertation describes the development of a mechanistic overlay design procedure. The mechanistic analysis represents a new trend in both new pavement and overlay design. The greatest advantage of the mechanistic pavement analysis is that it considers the fundamental characteristics of materials to be used, is capable of considering changes...

  • 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...

  • Nonlinear finite element analysis of reinforced concrete structures strengthened with FRP laminates

    Creator:
    Chansawat, Kasidit
    Abstract:
    The Horsetail Creek (HC) bridge is an example of an Oregon bridge that was classified as structurally deficient and was not designed to withstand earthquake (EQ) excitations. A fiber-reinforced polymer (FRP) rehabilitation was performed on the HC bridge to increase flexural and shear capacities for traffic loads. However, a seismic...

  • Three Essays on the Economics of Habitat and Landscape Restoration

    Creator:
    Nguyen, Tu
    Abstract:
    Natural landscapes around the world have experienced serious loss and degradation, which negatively impacts ecosystem service provision by these landscapes. As a result, there have been serious investments to restore natural capital. However, restoration faces complex trade-offs, such as that between restoration quality, or how closely the restored landscapes resembles...

  • Life in a Rapidly Changing Environment: The Thermal Biology of the Red-sided Garter Snake (Thamnophis sirtalis parietalis)

    Creator:
    Hubert, David L.
    Abstract:
    At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...

  • 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...
