Waterway is Public Works Landmark
The $2 billion, 234 mile Tennessee-Tombigbee Waterway connects the Tennessee River and the Gulf of Mexico at Mobile. The biggest Corps of Engineers civil-works project ever, it was created...
Construction of Roller-Compacted Concrete Pavement
Roller-compacted concrete pavement (RCCP) is the product of a relatively new concrete paving technology in which a zero-slump portland cement concrete mixture is spread with modified asphalt...
Explicit Integration of Boundary Integral Equations in the Frequency Domain for Wave Scattering Problems
The goals of this article are: (1) to present an efficient method for the integration of the boundary integral equations for wave scattering problems and (2) to apply this method to the...
Vibration Isolation of Structures From Surface Waves in Layered Soil
This work deals with the problem of isolation of structures from ground transmitted surface waves generated by machine foundations. The isolation is accomplished by means of rectangular...
Explosive Loading of Surface Ships
This paper describes the recent development of numerical methods which have accurately predicted the response of surface ships subjected to underwater explosion tests. The technique couples...
Computer Assisted Pavement
In Rancho Palos Verdes, Calif. a 4,300 ft. long test installation of the Contained Rock Asphalt Mat (CRAM) Pavement System is expected to have a 50 year life. It cost a third less than...
Influence of Surface Conditions on Surface Temperature
Geotechnical engineers working in areas of discontinuous permafrost are frequently faced with the necessity of designing facilities with a minimum of thermal disturbance. Construction...
Detention and Retention Controls for Urban Runoff
The operating principle for retention devices is the interception and capture of runoff, preventing its direct release to surface waters. The most common mechanism by which captured runoff...
Truck Weight Enforcement on a WIM
Pavements on interstate highways and other major truck routes are deteriorating faster than predicted. The cause is largely the larger-than-predicted number of the heaviest, 5-axle trucks....
Filling the Cracks
Engineers, highway officials, and manufacturers are working together to develop new products to rehabilitate cracked bridge decks. Polymer concrete overlays are among the many remedies...
New Runways Take Off
The two mile long runway 9-27, now being constructed at Houston Intercontinental Airport, was built for about 30% ($7 million) less than if designed conventionally. Rather than concrete...
Global Water Issues
Five critical global water-related issues are discussed. First is the issue of climatic changes and drought. Unfortunately, the opportunities to construct major irrigation projects are...
Cut-and-Fill Becomes Cut-and-Drain
The U.S. Navy's facility in Subic Bay, Philippines, is in a mountainous area which experiences 182 inches of rain per year. These factors plus weak soil, made necessary an...
Solutions for Pavement Rehabilitation Problems
Preservation of our nation's highways is the goal of highway civil engineers in the decades to come. The public travels on pavements and this important part of the system...
Managing the Highway System
There is a general feeling that increased emphasis on highway management is a promising approach to dealing with a series of apparent issues and trends: The inflating costs of substantial...
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...
Life Cycle Analysis
Of all the infrastructure elements, pavement performance has probably received more research than any. Similarly, there has been more application of pavement research. The concepts that...
Infrastructure Management and Planning for the City of Seattle
This paper summarizes the current planning effort that the City of Seattle's Engineering Department (SED) is undertaking for Transportation Infrastructure Management. The...
The National Infrastructure Act
Today, more than ever before, the United States faces a serious problem related to the condition and adequacy of its basic infrastructure - surface transportation, water supply and distribution,...
Biggest Highway Rebuild
The reconstruction of the Wisconsin Interstate 90 and 94 involved 32 miles of 6-lane pavement. Most of the concrete aggregate for the job was recycled concrete pavement and all pavement...
