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...

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...

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,...

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...

Economic Considerations in Selection of a Roller Compacted Concrete Dam
Roller compacted concrete (RCC) has recently emerged as an economically attractive material for gravity dam construction, replacing the use of conventional concrete and even challenging...

USBR Design Considerations for Roller Compacted Concrete Dams
Current Bureau design criteria for concrete dams are based on analytical methods developed and improved over the years, evaluation of construction methods and post construction materials...

Infrastructure for Urban Growth
Papers presented dealt with the financial, legal, political, planning, and engineering issues associated with providing public infrastructure necessary to meet the demands of growth in...

Highway Safety Forum
Advancing Road Transportation Safety Through Better Communication and Cooperation Among the Disciplines
Safe travel on our streets and highways has long received ample attention. However, there remains a relatively unexplored area within this subject. This area is communication between the...

Window Glass in Extreme Winds: Design for Flying Debris
Whether or not to change design procedures for window glass in buildings subject to very high winds was debated at the ASCE Convention in Houston. Preventing gravel and other debris from...

Peer Review: A Management Tool for Public Sector Projects
If done correctly, peer review can be an effective tool in managing public sector projects by reducing costs through careful weighing of design alternatives by experts in the field. The...

Civil Engineering Productivity�Can It Be Boosted?
In the past 20 years, construction labor productivity has declined while private business productivity has risen. And construction's percent of U.S. GNP has dropped nearly...

Water Supply Management Enters a New Era
Historical demand can no longer dictate water supply planning. The lessons learned in California are that changes in political and social attitudes require new approaches. Taxpayers are...

Can Management Techniques Solve Pavement Woes?
Cities are increasingly turning to systematic procedures for allocating scare manpower and funds and measuring pavement repair and rehabilitation needs. Many cities have adopted pavement...

Fluid/Structure Interaction During Seismic Excitation
Hydrodynamic loading and other fluid/structure interaction effects need to be considered in the design of structures which contain, surround, or are submerged in fluids when subject to...

Probabilistic Mechanics and Structural Reliability
Computing in civil engineering has gone through serious adjustments in recent years. With the advent of computer-aided design and drafting systems (CAD) and microcomputers, computing capability...

Assessing the Effects of Water Contamination
