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...

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 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...

A kinetic approach for the determination of sorption rate constants using a column-type reactor

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...

Startup and performance of a gas-permeable-membrane-supported (GPMS) biofilm system using a mixed culture of methylotrophs to degrade methylene chloride, chloroform, and carbon tetrachloride

Creator:: Ely, Roger L.
Abstract:: The methane monooxygenase (MMO) enzyme, used by methylotrophs to oxidize methane, has been shown to possess quite broad substrate specificity, being able to oxidize many organic compounds including n-alkanes, n-alkenes, ethers, and aromatic, alicyclic, and heterocyclic compounds. In this research, it was sought to determine whether a gas-permeable-membrane-supported (GPMS) biofilm...

A stochastic precipitation event model for use in erosion simulations

Creator:: Istok, J. D.
Abstract:: Mathematical models of the precipitation process are needed to effectively use historical precipitation data in the design and planning of engineering projects and for analysis of watershed runoff behavior. Existing simple models based on the assumptions of independent, identically-distributed random variables are insufficient to describe several features of the historical...

The application of centrifugal modeling to determine ice forces on isolated circular structures

Creator:: Clough, Herbert F.
Abstract:: A test system was developed and used to investigate ice/structure interaction with centrifugal modeling. The test system was designed to perform two main functions: (1) create a uniform ice sheet, and (2) drive a model structure through the ice sheet at a constant speed. Both of these functions were required...

The effect of organic sorbent concentration on sorption kinetics

Creator:: Dolan, Mark E.
Abstract:: Batch sorption tests were conducted using 3,4-DCP and cellulose triacetate as the sorbate/sorbent pair. Sorbate concentrations in the liquid were sampled with time and analyzed by electron capture detector gas chromatography. Sorption was found to be a two stage process characterized by a rapid initial uptake followed by a extended...

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...
