Barriers for Innovation and Technology Transfer in the Public Works Infrastructure R&D
Utilization of technologies and innovation to revitalize America's public works infrastructure is beset with barriers. Some critical barriers, identified through literature review and...

Modeling the Spatial Structure of Facility Condition
This study develops methods for information extraction that he bridge the gap between the detailed condition data collected by advanced technologies and the information necessary for maintenance...

Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...

Exploration of Ground Penetrating Radar for Railroad Tie Maintenance Scheduling
Assessment of railroad ties for replacement is currently performed by visual inspection. This paper describes a method of automated tie assessment using ground penetrating radar (GPR)...

A Condition Rating System for Rubble Breakwaters and Jetties
This paper describes one aspect of a series of projects which the U.S. Army Corps of Engineering has undertaken in an effort to improve maintenance management of coastal and navigational...

Using Condition Indexes to Evaluate Local Railroad Track Networks
The U.S. Army Construction Engineering Laboratories (USACERL) have developed condition indexes for assessing track condition that apply to local railroads. Indexes were developed for the...

Highway Maintenance and Integrated Management Systems
Maintenance management systems were among the first applications of rational management principles and the (then) the new technology of computers to highway operations. Recent changes...

TRACK(1.0): A Railroad Track Design and Evaluation Computer Program for Work Planning and Budgeting
This paper describes TRACK, a track structural analysis method and computer program developed by the U.S. Army Construction Engineering Research Laboratories. TRACK is a program for evaluating...

User Identified Short-Term and Long-Term Needs for Pavement Management Innovation
A survey involving 300 practicing engineer's from all over the United States and representing 20 other countries was conducted, concerning ideas and opinions of the priority research needed...

An Integrated System for Pavement Management
This paper describes the process of developing an integrated computerized pavement management system (PMS) for the New York State Thruway Authority. The process evolves around the integration...

Infrastructure Condition Forecasting Using Neural Networks
Condition forecasting models are critical components of any infrastructure management system. infrastructure condition assessed through periodic inspections which assign ratings to various...

Infrastructure Planning in Beirut, Lebanon
This paper presents a comprehensive framework for structuring the decision process of planning for transportation infrastructure rehabilitation and development in the city of Beirut, Lebanon....

Identifying a New Role of the Future Planner
It has been amply demonstrated over the last three decades that public planning is subject to great uncertainties, both in dealing with new technologies as well as in dealing with fuzzy...

Fuzzy Sets Model for Evaluation of Bridge Projects
This paper presents the formulation of a computerized decision support system that would aid the bridge engineer in long range planning of bridge funding needs, specially, to select the...

Digital Imaging as a Design Tool
On most engineering projects, schematic drawings offer a technical representation of a structure to clients. For staff or the public who are not technically knowledgeable, though, schematics...

High-Tech Landfill Caps
Just as federal and state regulations detail every aspect of landfill location, construction and operation, they now detail every aspect of its design closure. A typical municipal solid...

High-Speed Surface Transportation Cost Estimating
The cost of building and operating high-speed surface transportation (HSST) systems in the United States is a critical factor in determining their feasibility. Costs are difficult to estimate...

Development of Simulation and Cost Models to Compare HSR and Maglev Systems
Both high-speed rail (HSR) and magnetically levitated systems offer comfortable and safe ground transportation at high speed. The cost structure and performance of these systems and their...

The Megabight Barrier / Maglev Way?Innovative Siting of High Speed Ground Transportation...Offshore
Air and road traffic congestion around cities, e.g., in the BOSWASH corridor, can be reduced by high speed rail systems. But high speed trains on elevated rails/guideways encounter extra...

Concurrent Engineering Planning in HSGT Systems
Why should concurrent engineering concepts and TQM (Total Quality Management) procedures be considered for large scale HSGT (High Speed Ground Transportation) engineering and planning...
