Composites Enhance Timber Bridges
Two relatively new technologies are available for reinforcing or strengthening timber bridges with fiber-reinforced polymers (FRPs). The first consists in reinforcing the tension side...

Dual Benefits
When the Port of Houston needed to be dredged to accommodate larger commercial vessels, engineers decided to put the dredged material to use to create wetlands and islands that will serve...

The Road to Reuse
Many types of wastes and by-products have potential uses in the highway environment. Applications for recycled materials include asphalt pavement, portland cement concrete pavement, granular...

Megaproject Management
By the dredging and landfill project manager for the Port of Los Angeles and Alan E. Alcorn, P.E., an associate vice president of Moffat and Nichol Engineers in Los Angeles. The Pier 400...

New Navigation Channel
Among the facilities needed to accommodate Pier 400 at the Port of Los Angeles (POLA) was a new navigation channel to handle the increased container and liquid bulk traffic that the port...

Twenty-First Century Terminal
The Port of Los Angeles is already the busiest container facility in the United States, and the eighth busiest in the world. In 2000 it handled some 112 million tons (102 million Mg) of...

International Journal of Geomechanics
The International Journal of Geomechanics (IJOG) focuses on geomechanics with emphasis on theoretical aspects, including computational and analytical methods and related validations. Applications of interdisciplinary...

Closing in on Approval
A lack of qualification criteria and design standards has hindered some engineers from using fiber-reinforced polymers to restore concrete structures. But several organizations—among them,...

Moving Mountains
The earthmoving and rock-crushing operations at the Eastside Reservoir represented one of the largest such projects in the history of the United States. The earth and rock-fill dams required...

Experimental Approach
One of the best kept secrets during World War II, the K-25 facility in the Cumberland Mountains of East Tennessee prepared uranium for use in nuclear weapons. By 1987, the 13 million sq...

Walled In (Available in Geo-Environmental Special Issue only)
For more than 50 years manufacturing plants adjacent to the northeast bank of a midwestern creek produced asbestos-reinforced construction materials. When manufacturing at the plants ceased...

On Martian Soil
Discussions are ongoing about how and when to build human settlements on other worlds. Many scientific discussions have focused on settlements on Mars, and how the initial colonists would...

Road Test
The National Center for Asphalt Technology at Auburn University is building a $7 million, 1.8 mi (2.9 km) oval test track to perform accelerated pavement loading experiments. At least...
