Reuse Rules
Cities that discharge sewage effluent to surface water are under increasing pressure to reduce concentrations of heavy metals, ammonium and nitrate, and substances such as toxic organic...

Evaluation of Fine Aggregate Particle Shape and Texture
In an effort to minimize or eliminate permanent deformation (rutting) of heavy duty asphalt pavements most governing agencies now limit the amount of natural sand which generally (not...

Realistic Specifications for Manufactured Sand
Data which demonstrate the beneficial effect of using fine aggregate having high fines contents on concrete properties are presented. All data indicate that the use of a high fines content...

Performance of Free Draining Base Course at Fort Campbell, Kentucky
In 1990 a free draining base course layer was constructed in the structural section of a pavement to be used as a military vehicle maintenance yard at Port Campbell, Kentucky. The Corps...

Polyolefin Plastic Water Service Line Performance
Polyolefin (PO) plastic piping made from polyethylene (PE) and polybutylene (PB) materials have been used in diameters of about 1 in. for water service lines for buildings. Both PE and...

Stability and Performance of Slopes and Embankments II
This proceedings, Stability and Performance of Slopes and Embankments II, consists of papers presented at the Specialty Conference sponsored...

Embankment Dams
James L. Sherard Contributions
This volume is dedicated to the memory of Dr. James L. Sherard, who made many contributions to embankment dam engineering. Twenty-one of his papers related to this topic were selected...

Turning on the Waterworks
A new tunnel, two pumping stations, reservoirs and 150 mi of pipe have 23 municipalities in DuPage County, Illinois awash in Lake Michigan water, ahead of schedule and under budget. Bringing...

Seismic Hazards in the Eastern U.S. and the Impact on Transportation Lifelines
In the eastern US seismicity is low, hazard is moderate, and risk is quite high, especially in metropolitan regions with vulnerable transportation systems typically not designed to resist...

Seismic Hazard Along a Central U.S. Oil Pipeline
An integrated approach is used to evaluate seismic hazards at six sites where pipeline 22 crosses the major rivers in West Tennessee. On the basis of historical and instrumental data,...

Seismic Hazard Analysis for Crude Oil Pipelines in the New Madrid Seismic Zone
The seismic vulnerability of three crude oil pipelines in and around the New Madrid Seismic Zone (NMSZ) is evaluated for a repetition of the 1811-12 New Madrid events. The seismic hazard...

Migration of Spilled Oil from Ruptured Underground Crude Oil Pipelines in the Memphis Area
This study evaluated the impact of an oil pipeline rupture in the recharge area of a West Tennessee aquifer. Two potential break locations were chosen in the alluvial valley of a main...

Earthquake Countermeasures for Lifelines in the Central and Eastern United States
Seismic hazards affecting petroleum transmission systems in the Central U.S. and water and gas distribution systems in the Eastern U.S. are discussed. Experience during previous earthquakes...

Response of Model Pile Groups to Strong Shaking
The dynamic responses of small model pile groups to strong shaking obtained primarily from shake table tests are described and analyzed. As a basis for understanding pile group response,...

Seismic Pile-Group?Structure Interaction
A detailed multi-step procedure is outlined for a complete seismic soil-pile-foundation-structure interaction analysis, within the format of kinematic-inertial decomposition. Newly-developed...

Cone Models for a Pile Foundation
A single pile in a soil halfspace is modeled for dynamic excitation with disks and their corresponding double cones. This simple one-dimensional strength-of-materials approach provides...

The Superposition Approach to Pile Group Dynamics
A general three-dimensional boundary integral formulation for pile groups is used to obtain a set of dynamic interaction factors for a number of soil profiles and for a wide range of pile...

An Alternative Analysis of Vibration Tests on Two Pile Group Foundations
Published quick-release horizontal vibration tests on two pile group foundations supporting large transformer banks are analyzed in this paper using the dynamic impedance approach embodied...

Observed and Predicted Response of Piles Under Dynamic Loads
Vibration tests were conducted on a single pile 450 mm diameter and driven to a depth of 17 m. The dynamic soil properties were also determined by conducting in-situ tests. The response...

Forced Vibration Testing of an Expanded Base Concrete Pile
Forced vibration testing of a full-scale cast-in-situ expanded base concrete pile supporting a structural mass was conducted as part of a test pile program for a paper mill expansion at...
