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...
On the Elasto-Plastic Behavior of an Unsaturated Silt
Due to technical difficulties related to the control and measurement of the suction in unsaturated soils, few experimental data on the mechanical behavior of those soils exits. The paper...
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....
One and Three Dimensional, Three Phase Deformation in Soil
An initially saturated soil exhibits two distinct deformation patterns as it drys. First, it deforms vertically until the soil begins to drain. Secondly , it deforms laterally as well...
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...
Permeability Determination for Unsaturated Soils
A reliable approach for the determination of the soil hydraulic conductivity function relies on the parameter estimation solution approach in which heterogeneous state of saturation within...
Transit Times Through Compacted Clay Liners
Transit time, or time taken by waste liquid to move through the thickness of the liner, is a short-term performance parameter which can be used to determine the necessary liner thickness....
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...
Data Base for the Design of Piers in Expansive Soils
The paper describes the parameters and the structure of the seed of a data base of properties and observed field behavior of expansive soils assembled from an extensive literature review....

Whose Risk Is It, Anyway?
Near the now-closed Smuggler Mine in Aspen, Colo. toxic lead sits beneath the grass of area residents' yards. A major portion of soil in the area has lead above the EPA action...
Harry Seed, Liquefaction & the Gravel Drain
The late Professor Seed of the University of California at Berkeley established criteria for gravel drain design in a 1977 ASCE paper. Without historical proof for its viability in a real...
Two-Time Winner
After more than a century of service as a major U.S.-Canada rail link, the existing St. Clair River Tunnel between Port Huron, Mich. and Sarnia, Ontario is being replaced by a new tunnel...
Beach Nourishment with Aragonite and Tuned Structures
The first full-scale use in the United States of imported aragonite sand for beach restoration was undertaken at Fisher Island, Florida, between December 1990 and April 1991. About 20,000...
Monitoring of the 1988 Boca Raton Beach Nourishment Project
During July and August of 1988, approximately 843,000 cm of sand was placed along a 2.3-km stretch of beach in Boca Raton, Florida. Post-cosntruction monitoring of the beach nourishment...
