Investigation of a Concrete Blistering Failure
During construction of a concrete pavement at a military airfield, numerous small blisters formed on the concrete surface behind the slipform paver and were filled by the contractor using...

Performance of Epoxy-Coated Steel in Continuously Reinforced Concrete Pavement
Two sections of interstate highway in central Oklahoma were recently reconstructed. On both projects, northbound lanes were reinforced with epoxy-coated steel and southbound lanes were...

Transportation Planning and Air Quality
This proceedings, Transportation Planning and Air Quality, consists of papers presented at the National Conference sponsored by the Urban Transportation...

Environmental Engineering
Saving a Threatened Resource?In Search of Solutions
This proceedings, Environmental Engineering: Saving a Threatened Resource?In Search of Solutions, contains papers presented at the 1992 National...

Electrokinetic Cleanups
Electrokinetic remediation of contaminated soils is a relatively new research area. Electrokinetic phenomena can be used to create barriers, and move particles, including pollutants such...

Settling Down Easy
In order to more fully participate in the international and Asian Pacific aviation network, it was decided to establish a highly efficient 24-hour a day operation at the New Kansai International...

Ice Jam Configuration: Second Generation Model
An early model of ice jam configuration in wide, prismatic channels is generalized for applications to natural streams. Test runs are carried out to illustrate model performance and study...

A Conceptual Model for Vertical Frazil Distribution in Turbulent Flows
A conceptual model is presented for the evolution of frazil over depth in a turbulent flow. The net upward migration due to buoyancy of the frazil is opposed by intermittent mixing induced...

Heat Exchange at the Ice/Water Interface on Flowing Water
Any time the water flowing under an ice cover has a temperature above freezing, there is an exchange of heat between the water and the ice. Earlier work by Ashton and others provided adequate...

Small-Scale Meteorology of Freezing Precipitation
Freezing rain and glazing are extremely disruptive to transportation, communication and power transmission. Local variations in the occurrence of freezing rain may be difficult to forecast....

Multiphase Flows and the Modeling of Drifting Snow
Three categories of multiphase flow theories are commonly specialized for modeling drifting snow; the 'two-fluid' model, particle tracking schemes and kinetic...

Spray and Ice Measurement Instrumentation for Ships
Bow slamming is the primary water delivery mechanism for ship superstructure icing. Spray flux is largely dependent upon hull dynamics, and cannot be computed numerically with current...

The USACRREL Underwater Frazil Ice Detector
A modified underwater frazil ice detector has been developed at USACRREL. This detector, which operates remotely, can automatically start deicing procedures and alert operators to the...

Valuing Residual Emissions in Electricity Planning
Incorporating the valuation of residual emissions into calculations of social cost permits comparisons among alternative sources of electricity generation inclusive of environmental impacts....

Condition Assessment Experience with Silos and Bunkers
This paper presents a methodology for condition assessment of coal silos and bunkers for retrofitting projects. Some typical problems such as corrosion, erosion, vibrations and buckling...

The Future of Non-Utility Generation
The business of designing, constructing and operating non-utility owned electric power plants continues to evolve into the 1990s. The industry is consolidating as smaller market participants...

Will The Market in Emission Allowances Work?
The Clean Air Act Amendments of 1990 introduce a major new control program to mitigate the impacts of acid rain. The control program, which has been under debate for approximately a decade,...

Projections for Reduction in Lake Acidification From SO2 Emission Reductions
The Acid Deposition Assessment Model (ADAM) is used to assess the possible range of effects of a national acid rain emission reduction plan on lake chemistry and fish populations in the...

Optimization Models for Acid Rain Control
A series of related optimization formulations are presented for developing and analyzing acid rain control strategies. These models span a wide array of approaches and reflect a similarly...

Screening Emissions Control Measures
Under the new Clean Air Act, electric utilities will be able to choose from a wider range of sulfur dioxide emissions control options than in the past. Among the newly available measures...
