Quality Control Testing for a Sand-Bentonite Liner
This paper presents the results of the quality control testing performed during the construction of a sand-bentonite liner for a sanitary landfill site in Central Florida. The available...

Design and Performance Monitoring of Clay-Lined Landfills
The use of thick clay liners has been applied to Wisconsin landfills for over a decade. Currently, there are over 35 solid waste disposal facilities in Wisconsin which have been constructed...

Acceptance Sampling for Clay Liner Design
The assurance of the quality of constructed clay liners has been a problem for geotechnical engineers. Compliance with minimum standards is necessary to ensure the liner performance capability....

Influential Factors in Soil Liner Construction for Waste Disposal Facilities
Those factors most influential in the construction of a soil liner to meet a permeability performance standard of 1 multiplied by 10-7 centimeters per second (cm/sec) are identified and...

The Effects of Brine Contamination on the Properties of Fine Grained Soils
Laboratory tests have been performed to investigate the effects of brine contamination on grain size distribution, relative density, liquid and plastic limits, hydraulic conductivity,...

Permeability of Compacted Clay Liners in Laboratory Scale Models
Experiments conducted in flexible wall permeameters have shown that the permeability of a soil sample is dependent on the size of the specimen tested. The permeability was found to decrease...

Geotechnical Properties and Landfill Disposal of FGD Sludge
Extensive test data from more than a decade of research are compiled on the geotechnical engineering properties of flue gas desulfurization (FGD) sludges with emphasis on double alkali...

Quality Assurance Monitoring of a Large Clay Liner
The Keele Valley Landfill at Maple, Ontario, consists of a 99 ha (245 acre) facility to serve the Metropolitan Toronto area. The landfill is located in a former sand and gravel pit, with...

Hydrocarbon Refining Waste Stabilization for Landfills
Mobile pollutants are generated in a landfill as a function of the waste properties and the response of the deposit to the in-situ stress, climate and biochemical conditions. Release of...

The Typical Engineering Properties of Fly Ash
Knowledge of key physical and engineering properties of coal fly ash is needed in the planning, design, and construction of both disposal and utilization projects. While considerable data...

Water Treatment Plant Sludge as Landfill Liner
Chemical sludge is produced in large quantities during the water treatment processes. The present regulations pertaining to the disposal of solid wastes impose many constraints on any...

Environmental Monitoring and Observations Before and During Excavation of a Landfill in Owatonna, Minnesota
A Minnesota landfill inactive since 1962 was excavated in 1985 to prepare the site for construction of a new waste water treatment plant. The excavation refuse was disposed of in nearby...

Modelling of Contaminant Transport in Clays Via Irreversible Thermodynamics
This study develops a model for the analysis and prediction of contaminant transport in soils using principles of irreversible thermodynamics. The developed model includes five parameters...

Soil Improvement
A Ten Year Update
Since the publication of Soil Improvement?History, Capabilities and Outlook after the Annual ASCE convention in Philadelphia in 1976, a dramatic growth in certain soil improvement techniques...

Seismic Analysis of Safety-Related Nuclear Structures and Commentary on Standard for Seismic Analysis of Safety Related Nuclear Structures
This standard provides requirements for performing analyses to obtain design information which will lead to the reliability of structures under a severe earthquake. The goal of this standard...

Use of Vibration Measurements in Structural Evaluation
Over the past decade the capabilities for vibration measurements and analysis have advanced significantly. It is now a routine procedure to be able to measure natural frequencies of structures...

Engineering Aspects of Soil Erosion, Dispersive Clays and Loess
This collection of papers deals with selected engineering aspects of soil erosion, dispersive clays and loess. Two types of erosion are considered?surface and subsurface (piping)?with...

The Mexico Earthquakes?1985
Factors Involved and Lessons Learned
This publication reports initial results of study of the 1985 Mexico earthquake, one year after the event. The findings present sufficient depth of analysis to provide an understanding...

Planning by Database
Denver's Stapleton International Airport cannot handle the growing volume of air traffic and will be replaced by an entirely new $3 billion Denver Metropolitan International...

Hydraulic Structures on Piles
Many hydraulic structures built in the early 1900's were founded on piles. Today, when these structures are analyzed as 'pile-supported', the analyses...
