Delaware Estuary Nonpoint Source Control Program
Preparation of the Delaware Estuary Management Plan, sponsored by the EPA and the three states of New Jersey, Pennsylvania and Delaware, is part of the national estuaries program. As part...
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...
Overview of Permeable Bases
Drainable pavement systems consist of: permeable base, separator lyer, and edgegrain system. This paper focuses on permable bases. A permeable base must provide both permeability and stability....
High Strength, Low Permeability Garage Rehab Concrete
Physical and engineering properties of high strength structural lightweight concrete used to replace deteriorated concrete in garage structure rehabilitation programs are reported. Structurally...

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...
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...
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...
First and Second Order Dynamic Subgrade Models for Soil-Pile Interaction Analysis
The three-dimensional continuum solutions are used to examine the physical insight of a first order dynamic subgrade model, originally applied by Novak for dynamic pile response analysis....
Effects of Liquefaction on Lateral Pile Responses
The potential significance of the impact of liquefaction on the dynamic response of pile foundations has been studied through a numerical study. Results of this study demonstrated that...
