Burrowing Beneath Bangkok
The $2.9 billion Bangkok subway project faces several daunting obstacles�soft soils, a high water table and Thailand's current economic upheaval. The Blue Line subway system...
Stretching a Landfill
Landfill expansions can pose engineering challenges, and the Tullytown, Pa., landfill gives an example of a horizontal expansion that added 121 acres of future disposal space. The side-by-side...
Jet Grouting: New Directions
This article looks at jet grouting in soft soils, especially applications involving pre-installed structural supports for cut and cover excavations. The author offers a question and answer...
Preparing for Pier A
Earthquakes, oil wells, contamination and unstable soil were among the challenges engineers faced as they prepared a site at California's port of Long Beach for the Pier A...
The Search for HPC (Available in Structural Engineering Special Issue only)
High-performance concrete (HPC) is often overlooked by engineers because its properties are not well documented. Concrete Clinic International conducted a study to learn more about the...
Paper Mill Sludge Landfill Cover Construction
A considerable amount of experience has been acquired from a number of completed paper mill sludge landfill covers within the United States. This paper focuses on practical guidelines...
Geotechnical Performance of a Highway Embankment Constructed Using Waste Foundry Sand
A highway embankment was constructed near Auburn, Indiana, using waste foundry sand (WFS) as a demonstration project for the Indiana Department of Transportation (INDOT). Laboratory testing...
Using Waste Foundry Sand for Hydraulic Barriers
Green sand is a mixture of uniformly graded fine silica sand, bentonite, and organic binders that is used to make molds for castings in gray-iron foundries. Large quantities of waste green...
Recycled Materials for Embankment Construction
Obtaining good quality soils at reasonable costs for use in embankment construction is becoming difficult and hence, attention is directed towards finding alternative materials. On the...
Utilization of Lagoon-Stored Lime in Embankment Construction
The maximum percentage of lime that can be mixed with a predetermined borrow material to build the proposed road embankment without adversely affecting the physical and mechanical properties...
Role of Constituents on the Behavior of Flowable Fly Ash Fill
Flowable fills are increasingly used as backfill materials for pipes and retaining structures because of ease of placement and performance of the solidified material. But the role of its...
The Safe Disposal of Fly Ash in Pavement or Earth Structures Not Requiring High Strength Materials
Highway agencies throughout the country face the challenge of safe disposal of various waste products in pavements and earth structures. Some of these waste products can be hazardous to...
Crushed Hydrated Fly Ash as a Construction Aggregate
Hydrated fly ash (HFA) is being produced in Texas by first adding water to Class C fly ash and allowing it to hydrate in curing pits for several weeks. HFA typically attain unconfined...
Compaction Characteristics of Contaminated Soils-Reuse as a Road Base Material
Contaminated soils generated from leaking underground storage tanks (USTs) sites are classified as solid waste or non-hazardous waste. Since petroleum contaminated soils are solid waste...
Alternative Landfill Covers Pass the Test
Researchers at the Sandia National Laboratories in Albuquerque, N.M., are conducting a large-scale field demonstration comparing final landfill cover designs in arid and semi-arid regions....

Test Wall Promises Big Savings (Available in Geo-Environmental Special Issue Only)
A new kind of retaining wall is being tested in Texas at a National Geotechnical Experiment site. The wall is a variation of soil-mixing that uses fewer columns, which saves time, materials...
The Deep (Available in Geo-Environmental Special Issue only)
Despite a mere 1,500 ft separation, Baltimore's Oriole Park at Camden Yards and Ravens Stadium required vastly different deep foundation solutions. While Oriole Park is founded...
