Haunted by the Past
Given the legacy of the construction of the Missouri Valley Water Tunnel in the 1920s�eight deaths and numerous injuries�it's no wonder that safety was foremost in the minds...
Use of Self-Cementing Fly Ashes as a Soil Stabilization Agent
Fly ash produced in the combustion of subbituminouns coals exhibits self-cementing characteristics that can be adapted to a wide range of stabilization applications. Ash treatment can...
Flyash Stabilization of Tropical Hawaiian Soils
A preliminary study of soil improvement/stabilization of several tropical Hawaiian soils with locally generated high quality flyash admixtures has shown tremendous potential as an economical...
A Study of Engineering Properties of a Clay Modified by Ash and Slag
Fly ash from power plants and slag from steel mills are two industrial solid wastes. These wastes can be utilized as soil stabilizers. In this study, a clay with low plasticity is mixed...
Treatment of Calcareous Expansive Clays
The geology, climatic condition and the environment of extreme disintegration, strong hydration and restrained leaching have a large influence on the formation of expansive clays in the...
Behavior of Suction Piles in Sand
In the marine environment, use of suction pressure for the installation of sealed top piles (suction piles) is a promising alternative to driven pile foundations, particularly in deep...
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...
Hong Kong's Wastewater Underground
Standard Hong Kong methods for siting the new $18 million Stanley Wastewater Treatment Plant in Hong Kong Island's South District were running into trouble. The rocky coastal...
Exchanging Wastes
For several years, thousands of cubic yards of dried sludge have been stockpiled at the Greater Peoria Sanitary District's wastewater-treatment plant in Peoria, Ill., because...
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.,...
