Secondary Member Contribution to the Behavior of Damaged Multigirder Highway Bridges
This paper examines the effects of secondary members (cross bracing and diaphragms) on the prediction of the response of damaged simple span steel multigirder bridges. Extensive analytical...

Time-Dependent Analysis of Nonprismatic Curved PC Box Girder Bridges
The purpose of this paper is to present a step-by-step computer method for predicting the deflection and stress distribution duo to creep and shrinkage of concrete in nonprismatic, curved,...

Highway Speed Radar for Pavement and Bridge Deck Evaluation
Radar has been developed as an economical alternative evaluating pavement layer properties and estimating quantities of deterioration in bridge decks. These highway applications are based...

Benefits From Improved Management of Pavement Facilities
Effective management of pavement facilities can provide several benefits both the agency and the travelling public over the long term. The benefits achieved from improved rehabilitation...

Evolution of Pavement Management Systems at the Port of Authority of New York and New Jersey
The Port Authority of New York and New Jersey (the Port Authority) operates the world's largest and busiest airport complex as well as an extensive roadway network. To provide effective...

Bridge Monitoring Through Sensor Data Synthesis and Interpretation
The objective of this paper is to outline efforts at the West Virginia University Constructed Facilities Center (CFC) to develop and implement a system for interpretation and synthesis...

A Graphics-Based System for Urban Roadway Management
This paper describes a graphics-based system for urban roadway management. The main objective of the system is to select the cost effective maintenance and rehabilitation (M&R)...

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...

Highway Investment Analysis: The Next Generation
The Department of Transportation has developed and is now testing a state-of-the-art modeling procedure which simulates highway improvement selection decisions based on the relative benefits/cost...

French Road Works and Public Transport Investments
A detailed analysis of public highways and urban public transport investments over the period 1984-88, in sixteen French cities, has enabled us to conclude that these expenditures are...

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...

Implementation of a District Level Highway Routine Maintenance Needs Assessment Program
A routine highway maintenance needs assessment program allows a transportation agency to establish a maintenance work program consistent with the objectives of a pavement maintenance management...

Economic Paradigms for Infrastructure Management
A key characteristic which has emerged in infrastructure management system is the use of economic models at the network level (as opposed to project level) to help in evaluating program...

Applying PMS Lessons to New Infrastructure Tools
The objective of this paper is to present a historical summary of the factors which have influenced the successful implementation of pavement management system (PMS) for the lessons learned...

Congestion Management?Opportunities for States and MPOs to Ensure the Efficiency of Their Highway Systems
The Clean Air Act Amendments of 1990 (CAAA) and the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) are effecting change in multimodal transportation decision making....

The State of the Art of Bridge Management Systems
The development of Bridge Management Systems, and Pontis in particular, requires states to change many of their traditional inspection and record-keeping procedures. If these are changed,...

Highway Maintenance Data Collection: State of the Art
Existing procedures for recording highway maintenance and field inventory data re laborious and time consuming because the information is entered twice - first on standard paper forms...

Automated Generation of NBI Reporting Fields from Pontis BMS Database
Methods to generate National Bridge Inventory (NBI) condition ratings for deck (Field 58), superstructure(Field 59), substructure (Field 60) and culvert (Field 62) from the bridge database...
