Aspects of the Behavior of Clays on Drying
The drying behavior of compacted London Clay mixed with varying proportions of fine sand is examined, measuring the changes of sample volume, water content and suction. Particular attention...
The Transistor Psychrometer: A New Instrument for Measuring Soil Suction
The transistor psychrometer is the latest instrument available for the measurement of soil moisture suction. It has been developed over a number of years and is very similar in operation...
Modelling the Behaviour of Compacted Soils
Predictions based on a recently developed model for unsaturated soil behaviour have been compared with some results of two experimental programs on compacted soils recently published in...
Elasto-Plastic Volume Change of Unsaturated Compacted Clay
Isotropic compression tests were performed on samples of unsaturated compacted kaolin in a modified triaxial cell that allowed separate control of pore water pressure and pore air pressure....
Flow Properties of Unsaturated Soils Under Controlled Suction
Laboratory tests were performed for the hydraulic characterization of three compacted soils under high suction. Moisture changes were studied considering some factors affecting the time...
Performance of Horizontal and Vertical Barriers
Horizontal and vertical barriers have been used on transportation facilities to control expansive soils and minimize their damages. The effort is to minimize moisture change in the soil...

Vietnam: Worth Looking Into
If it is to enter the world economy, let alone play catch-up with the booming economies of some of its neighbors, Vietnam requires massive numbers of infrastructure projects: roads, bridges,...
The Financing Fray
Interview with two executives of the U.S. firm Morrison-Knudsen: Donn Smith, senior vice president of project finance at M-K's International Group, and Richard White, vice...
Dutch Globetrotting Pays Off
The Dutch have been doing business overseas for centuries, and Dutch consultants today continue the tradition. Several Dutch consulting firms are profiled. At Fugro-McClelland, N.V., Chief...
Runoff As A Resource
Recent studies have shown that storm-water flows from urban and industrial areas typically contain significant quantities of the same pollutants found in wastewater and industrial discharges....
Reclaiming Clear-Cut Land
The Savannah (Ga.) Airport Commission needed to expand the city's international airport to meet projected needs through 2007. The expansion was designed with Greiner, Inc.,...
Infratechnologies: Tools For Innovation
Infratechnologies support the practices of construction over the whole life cycle of constructed facilities. They include technologies for developing and applying information, standards,...
The Big No-Dig
As part of the Boston Harbor cleanup project, engineers will have the opportunity to make a rare, side-by-side comparison of open-cut construction and no-dig technology during the Wellesley...
Egypt's Real-Time Water Management
The challenge and complexity of efficiently managing the distribution of the 55 billion m that Egypt draws from the Nile every year has prompted the country's Ministry of...
Dispute Avoidance
Dispute avoidance is not something that begins at ground breaking. Dispute avoidance is not a technique that helps you resolve the inevitable problems that arise during construction. Dispute...
In-Service Durability Evaluation of Armourstone
A summary flow diagram for rock evaluation, general to all rock types and engineering applications of rock is introduced. It is then applied to armourstone. Increasing detail within this...
Laboratory Testing of Stone for Rubble Mound Breakwaters: An Evaluation
The quality of the final stone product hinges on the combination of two factors - rock properties and environmental conditions. The environmental conditions associated with production...
U.S. Experience With Armor-Stone Quality and Performance
In the past 30 years problems with deterioration and cracking of armor stone in the United States have been concentrated in northern regions, particularly around the Great Lakes. The explanation...
Problems With Armor-Stone Quality on Lakes Michigan, Huron, and Erie
The instances of deterioration of armor stone at coastal structures on the Great Lakes result from numerous distinct causes, both intrinsic and extrinsic. However, the proof of specific...
