Costs of Truck Related Highway Damage to Alaska
The cost of pavement damage to the State of Alaska for truck traffic continues to be a very controversial topic. There is no simple answer since this cost is dependent upon pavement strength,...
Reinforced Roads Bridging Voids
A mathematical model was developed to design a pavement section reinforced with a geotextile or related product to span a void. A full scale field test was conducted to verify the model....
Economic Analysis of Highway Safety Projects
The most commonly used economic analysis for highway safety projects is the cost-benefit ratio. While this is a valid analytical tool, it must be used correctly to produce valid results....
Evaluation of Safety Alternatives by Benefit/Cost Analysis
There is an increasing awareness of the need to use limited highway safety funds on projects that offer the greatest benefits. This paper describes the development and application of a...
Shoulder Rumble Strips at Narrow Bridges
The highways in the United States have thousands of minimum design narrow bridges. Replacement of these bridges with current state of the art designs is not cost effective nor feasible...
Expert System Tools for Civil Engineering Applications
Expert system software tools have played a major role in expediting program development. Some problems should not and possibly cannot be solved by current expert system technology. For...
Delineation Effectiveness for Alcohol Involved Accidents
The approach to the problem of the alcohol impaired drivers to date has been directed at driver education and increased police enforcement. A complementary and parallel approach is presented...
Efficiency Gains Using Micro Computers in Marina Design Engagements
This paper addresses improved efficiency in marina design engagements using low cost micro computers and low cost software. From the preparation of an offer for service, through design,...
Recent Trends and Advances in Bulk Cargo Unloading
The progress in loading of bulk cargo into ships has matched the advances in ships' size. The same could not be said for getting bulk material out of the hold of a ship, in...
Improving Maintenance Performance
This discussion concerns Maintenance Management concepts that emphasize how the human element among Port personnel can be organized and efforts channeled so as to: increase the actual...
Computer Pricing Practices
Civil engineers have become increasingly involved with the use of computers to help solve engineering problems. Many problems that previously could be solved only approximately, or that...
Treatment Facilities and Costs for the Removal of Radon from Ground Water Supplies
Two methods for removal of Radon from drinking water are considered: activated carbon adsorption and packed tower aeration. Although both granular activated carbon (GAC) and packed tower...
Current Status of Flue GasDesulfurization in the United States
Flue gas desulfurization (FGD) systems have been in existence in the United States for only 17 years but they have made a tremendous impact in the operation of utility plants. At present,...
Sea Level Rise and Coastal Stormwater Drainage
Global sea level rise as a result of the greenhouse effect and the past trend and future projection on the rise are discussed. Potential problems associated with coastal stormwater drainage...
Optimizing Drain Spacing and Depth Using Steady State Equations
A method is developed for minimizing the total cost of establishing relief drains by choosing appropriate depth and spacing of the drains. Solution graphs are presented for a wide range...
Making Water System Rehabilitation Decisions
Making decisions regarding water distribution systems has always involved a great deal of judgment due to the complexity of the decisions involved. This paper presents a framework for...
Water Infrastructure Maintenance Needs?A Case Study
Adoption of measures to prevent loss of water in many cases is cost-effective. In order to illustrate the magnitude of infrastructure problems of large cities, a test case infrastructure...
Transferring Conserved Water
The proposal to transfer water salvaged by water conservation programs from one area to another is a new concept. Imperial Irrigation District (District), located in the southeast portion...
Sediment and Erosion Control Implementation: An Overview
The responsibilities of the federal, state and local governments in sediment and erosion control are reviewed. The effectiveness of cost-shared and non-cost-shared technical assistance...
Hydraulic Reliability of Urban Water Distribution Systems
