Effective Communications in Highway Safety Programs
The problem of creating a safe environment for the users of our highway system has been with us almost since the invention of the motor vehicle. Generally accepted throughout the field...
Highway Work Zone Safety
The objective of this presentation is to provide discussion on how to improve the interdisciplinary information exchange to enhance safety on roads and streets from the viewpoint of the...
Communication?A Common Vision
It is imperative that lines of communication remain open between those who represent the 'state of the art' in safety. The common goal of these interrelated disciplines...
Human Factors: The Problem with the Problem
Human behavior in the highway transportation system is prone to error and has basic limitations. It is modifiable within those basic limits. Most often we focus attention on the behavior...
Interdisciplinary Communication and Traffic Safety: An Information Systems View
The purpose of this Highway Safety Forum is to find ways to improve communications among professionals in eight disciplines which are involved in the effort to reduce the number and severity...
Highway Safety Design Communications
This paper gives an examination of problems and prospects of incorporating more current highway safety knowledge into the design process through promising communication linkages between...
Vehicle Design Exchange With Other Disciplines
Vehicle Design as one of the eight designated areas of interest or 'disciplines' includes a wide range of interests within itself. It can range from overall vehicle...
Tampa Does It with Mirrors
As one of the nation's fastest growing cities, Tampa needed far more public works dollars. But the traditional source, the real estate tax, can no longer be relied on so heavily,...
Slurry Walls Protect Harvard Square
Harvard Square Station, Cambridge, Mass., had to be rebuilt when Boston's Red Line Subway was extended further out to the suburbs. For the first time, tied back slurry walls...
Pipe Laying Comes Out of the Trenches
Recent developments have shown that trenchless construction offers an effective and economically attractive alternative to conventional excavation. These findings are especially important...
Engineering with Fabric
Geotextiles are lending their strength to construction projects where conventional methods won't work. At Washington National Airport, an embankment was built into the Potomac...
Beam Analogy for Vertical Curves
The vertical curve is analyzed as a moment diagram for a uniformly loaded single beam with a concentrated moment at one end. This contributes some flexibility in approach, and enhances...
San Francisco Outfall: The Champ?
The Southwest Ocean Outfall, with an overall length of 23,400 ft and capacity of 450 mgd, will be major element of the Clean Water Program of the City and County of San Francisco. Offshore,...

Steel fiber reinforced shotcrete (SFRS) costs less, has a lower rate of rebound and allows modern excavating equipment to advance with fewer interruptions than conventional shotcrete....
Ethics in the Field
Just as a child matures through various stages of moral development, the engineer too undergoes professional moral development described by psychiatrists. Development comes in six stages...
Unearthing Mt. Baker Tunnel
A new tunnel under Mt. Baker in Seattle is part of major improvements to I-90 between Bellevue and Seattle's business district. Feasibility studies began in 1963, but it was...
Current Corps of Engineers Concepts for Roller Compacted Concrete in Dams
Since construction of Willow Creek Dam in 1982, Elk Creek Dam in southwest Oregon is the only Corps of Engineers dam to be constructed using RCC that has passed beyond the planning stage...
Watertightness and Seepage Control in Roller Compacted Concrete Dams
An unjointed mass of roller compacted concrete (RCC) can easily be proportioned and compacted so that it is essentially impermeable and 'watertight. ' Permeability tests of various field-placed...
Roller Compacted Concrete Pavements in British Columbia, Canada
Roller Compacted Concrete (RCC) pavement is an outgrowth of the traditional cement-treated aggregate base (soil-cement) method of street and highway construction. The major use in British...
Simplified Design and Construction Control for Roller Compacted Concrete
This paper presents a simplified approach to the design and construction quality control of roller compacted concrete (RCC) based on research of previous projects, discussions with experienced...
