  • Computer simulation of offtracking of truck and trailer combinations using forest roads

    Creator:
    Erkert, Thomas W.
    Abstract:
    Many of the analytical techniques that are currently available are not capable of analyzing the offtracking of truck and trailer combinations or the path of load overhangs through a set of curves that are commonly found on forest roads. Advances in the processing speed of microcomputers have made it possible...

  • Evaluation of cold in-place recycling of asphalt conrete pavements in Oregon

    Creator:
    Scholz, Todd
    Abstract:
    Significant use of cold in-place recycling (CIR) has occurred in Oregon since 1984 as an alternative to other rehabilitation techniques or to the reconstruction of distressed asphalt concrete (AC) pavements. Due to the initial success of the projects cold recycled during 1984-85, the Oregon Department of Transportation (ODOT) and Oregon...

  • Bus accessibility for persons with sensory disabilities

    Creator:
    Hron, Martha
    Abstract:
    With the passage of the American with Disabilities Act (ADA) it has become a civil rights violation to deny access to persons with disabilities to public transportation. The ADA requires transit agencies to provide accessible buses or equivalent services to persons with mobility, sensory or cognitive impairments. This study examines...

  • A validation of the Oregon State University driving simulator

    Creator:
    Brown, Lacy S.
    Abstract:
    Driving simulation is widely accepted as a safe, effective, and economical alternative for investigating driver behavior in a variety of contexts. However, in order to apply simulator-based research results to real-world settings, the performance measures acquired through simulated driving experiments must first be validated. This research was aimed at validating...

  • The physiological effect of posture on cycling

    Creator:
    al-Haboubi, Muhammad
    Abstract:
    The objective of this research was to investigate the physiological effects of body posture on cycling. The familiar positions of bicycle riding have been the touring posture (hands stretched on top handlebar) and the racing posture (hands bent at the elbow, with the back horizontal). However, a relatively new stance...

  • 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...

  • 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...

  • Bond strength investigations and structural applicability of composite fiber-reinforced polymer (FRP) rebars

    Creator:
    Kachlakev, Damian I.
    Abstract:
    The composite FRP rebars research at Oregon State University was initiated in 1993 principally to develop a non-metallic hollow reinforcement. It was recognized that the tensile properties of such reinforcement are unquestionably superior to steel, but its performance in concrete could be problematic. The bond between FRP rebars and concrete...
