Creator:: Barrero-Quiroga, Franklin
Abstract:: This paper presents an application of the wave equation to the problem of selecting a driving hammer for prestressed concrete piles. The potentially damaging effects of these types of hammers on various prestressed concrete piles were analyzed by means of parametric studies carried out on a hypothetical group of problems...

Creator:: Chang, Chen
Abstract:: Coastal Oregon is deficient in quality construction aggregate. There is, however, an abundance of lower quality, or marginal aggregate available for construction purposes. The purpose of this report is to develop techniques for upgrading marginal aggregates with portland cement and methods for evaluating the relative performance of these stabilized materials...

Creator:: Patrier, Lionel
Abstract:: A Langmuir sorption model incorporating a second step of irreversible absorption was applied to a model soil system. The column was packed with cellulose triacetate; pulse and step input tests with 3,4-dichlorophenol were performed; the effluent concentration was measured by electron capture detector gas chromatography and sorption rate constants were...

Creator:: Kim, Young
Abstract:: Batch microcosm studies were carried out to screen for microorganisms from the subsurface of Hanford DOE site that could cometabolically transform chloroform (CF) under aerobic conditions. The potential need for CF bioremediation at the Hanford site has resulted from the large release of carbon tetrachloride (CT) to the subsurface, of...

Creator:: Nichols, Kevin Scott
Abstract:: Evaluation of the safety hazards along a highway is usually performed at specific locations and on known hazards. But, it is also important to find any unrecognized hazards and their locations. Many factors contribute to accident potential, and the combined effect of several of them could produce a hazard that...

Creator:: Sujjavanich, Suvimol
Abstract:: Environmental factors and physical properties of latex modified concrete (LMC) are hypothesized to contribute to early age cracking in bridge deck overlays. Cracking permits the ingress of moisture and aggressive solutions into the substrate and may contribute to other subsequent distresses. Understanding the material properties and mechanisms involved is necessary...

Creator:: Ab-Wahab, Yunus Bin
Abstract:: Testing of asphalt binders and asphalt-aggregate mixtures using dynamic mechanical analysis is becoming popular with improvements in high-speed computers, precision equipment, and computer software. Researchers are trying to describe the behavior of asphalt binders and asphalt-aggregate mixtures in terms of their time- and temperature-dependent linear viscoelastic behavior. The objectives of...

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...
