Survey of Airport Pavement Distress in Cold Regions
The most common pavement problems were associated with non-traffic related phenomena and included pre-existing cracks reflecting through asphalt concrete overlay (in two years or less),...
Wastewater Plant Cold Weather Operational Problems
A questionnaire survey was conducted at biological wastewater treatment facilities in northern New England. Problems associated with various unit processes, due to cold weather operations,...
Selection of Performance Levels for Longitudinal Barriers
There is a demand within the highway community for multi-service level safety features, including traffic barriers. The need has become more acute in recent years as revenues decline and...
Performance of Highway Traffic Barriers
This paper describes an investigation of traffic barrier performance in New York State. A one-year sample of all traffic-barrier accidents in the state was obtained from Department of...
Assessment of Safety Impacts of Highway Projects
In this paper the safety impact of highway improvement and maintenance activities is examined in terms of accident reduction potentials of these activities. There are three causes of accident:...
Innovations in the Design of Electrical Transmission Structures
New concepts are being advanced for the design of electrical transmission structures. The papers in this book cover the following: weather-element loading conditions, structural options,...
Boundary Conditions for Multiple Bifurcations
Co-ordinated Microcomputer-Based Rain Data Network and Modeling Environment
A co-ordinated microcomputer controlled rainfall collection network has been designed which includes drop counting precipitation sensors, tipping bucket raingauges, Z80-A microprocessor...
Winter Highway Construction
The purpose of this paper is to describe a study of the feasibility of constructing highways in the wintertime in cold regions. The study, sponsored by the Alaska Department of Transportation...
Diffraction Forces on Axisymmetric Bodies
Use of a Green function satisfying the governing differential equation and all boundary conditions except those on the boundary of the structure yields an integral equation, when these...
National Urban Transportation Planning Trends and Implications
This paper explores urban transportation planning, program, and policy trends of the 1980s. Legislative and regulatory changes are also addressed. Among the planning trends discussed are...
Pavement Management Systems for Urban Areas
Pavements represent the largest public investment for most urban-area governmental jurisdictions. The magnitude of this investment requires that the expenditure of funds to maintain pavements...
Evaluation of Runoff Prediction Using Synthetic Rainfall and CREAMS
Of all the climatological data, rainfall is the variable to which a watershed responds most significantly. The amount and sequence of occurrence of rainfall are most important in the prediction...
Innovative Strategies to Improve Urban Transportation Performance
The field of urban transportation is facing some severe challenges. Roadways continue to deteriorate, the financial condition of public transit systems is abysmal, and general productivity...
Characterization of Indoor Carbon Monoxide Levels Produced by the Automobile
Integrated air samples were obtained at seven small and six large service stations and two dealerships. These establishments were sampled during cold and warm weather operations for eight...
Rainfall Results of the Florida Area Cumulus Experiment and Their Implications for Drought Problems in the South
Evidence is presented for treatment effects during the Florida Area Cumulus Experiment (FACE). The sizes of the apparent effects are a function of scale, largest for the cell scale and...
Microcomputer Program for Daily Weather Simulation
Extensive climatic data have been collected by the National Weather Service and other agencies, and are available in printed form or on magnetic tapes. The published data are expensive...
Transmission Tower Foundations in Weathered Rock
A case history is presented which discusses the siting, design and construction of the tower foundations for a transmission line in southwest Alaska. The project, completed in 1983, consists...
Concrete Face Rockfill Dams of the Winneke Project
Two of the three dams forming the Winneke Reservoir, near Melbourne, Australia, are concrete face rockfill dams. A minor dam forming the sludge storage pond for the project's...
Recent Developments in Resonant Column Testing
