Engineering Aspects of Wetland Design
Successful wetland enhancement, restoration, or creation projects require integration of desired wetland functions, local hydrologic and soil conditions, and biological requirements into...
Highway Construction and a Trout Stream Relocation
In 1970, a ten-mile section of Traffic Route 15 in the northern portion of Lycoming County extending into Tioga County was under design as a two-lane limited access highway on four lane...
Development of a Phase I Prescriptive Reservoir Model
The U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC) has recently developed a Phase I generalized prescriptive reservoir model referred to as HEC-PRM. The purpose of the...
Proposed Development of South Central Florida Hydrologic Ecosystem Model
The Corps of Engineers has been authorized to develop and operate a simulation model of the hydrologic ecosystem of central and south Florida. This ecosystem is fragile and complex, and...

Site Impact Traffic Assessment
Problems and Solutions
Transportation needs have traditionally derived from land use decisions. Site impact traffic analysis is a formalized process that attempts to quantify the need for transportation improvements...
Steering Clear of Tort Claims
Tort liability has become a major issue for today's highway engineer. Claims against state highway departments charging that deficient roadways caused or contributed to traffic...
Investigation of a Concrete Blistering Failure
During construction of a concrete pavement at a military airfield, numerous small blisters formed on the concrete surface behind the slipform paver and were filled by the contractor using...
Standard Methodologies for the Forensic Investigation of Pavements
The high costs of new construction have made the preservation and restoration of existing pavements an attractive alternative to replacement structures. Existing pavements that are to...
An Airfield Pavement Forensic Analysis: Cairo East Air Base
The US Army Engineer Waterways Experiment Station (WES) was requested by the Middle East/Africa Projects Office in April 1989 to provide technical assistance in analyzing an unstable asphalt...
Forensic Analysis of a Two-Component Joint Sealant Using FTIR-ATR
Fourier-Transform Infrared Spectroscopy using Attenuated Total Internal Reflectance (FTIR-ATR) was used to chemically identify joint sealants obtained from an airfield pavement joint which...
The Diagnosis of Pavement Ills
The paper defines the 'health' of a road pavement in terms of parameters of serviceability, safety and structural integrity and defines 'illness' as any departure from 'healthy' values...
Successful High Traffic Chip Seal Construction
Chip seal coats are used to extend pavement service life by reducing water and air infiltration and improving skid resistance. Application of chip seals is usually limited to low-traffic...
Procedures for Evaluating Aggregate Gradation Specifications
The construction and rehabilitation of transportation facilities annually consumes huge quantities of aggregates. And, the variability in supply and demand for these materials as well...
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....
Forensic Analysis Techniques for Joint Sealants
Growing concerns involving the field performance of pavement joint sealant materials has illustrated the need for forensic capabilities in determining the cause of sealant failures. Methods...
Implementation of Material Requirements in Specifications
This paper focuses on where to find information on materials, their compatibility, minimum standards and specifying of materials and their use. The paper also presents case histories on...
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...
