On February 26, 1993, a bomb exploded in an underground parking garage beneath the World Trade Center, killing six, causing hundreds of millions of dollars in damage and leaving a crater...
Nondestructive Evaluation Techniques and Their Role in Infrastructure Management
Nondestructive evaluation (NDE) techniques can play an important role in infrastructure management. They can be used to assess current condition a well as to predict future performance...
Sonic NDT for Infrastructure Assessment
Sonic Nondestructive Testing (NDT) techniques are valuable tools for assessing infrastructure. Relatively recent innovations in the field can reveal the internal conditions of concrete...
Promoting Management Systems Within Organizations
The major effort during the years in which pavement management emerged as an accepted practice was making refinements to the technical models and techniques in the systems. For example,...
How to Get Local Public Works Agencies to Use Structured Infrastructure Management Approaches
As more agencies consider adopting infrastructure management systems, the lessons learned in developing and supporting the use of current systems should be used to structure the support...
Algorithm for Crack Detection in Automated Pavement Analysis
This paper summarizes recent research in various algorithms for detection of pavement cracks. The most successful algorithms use a digital filter to obtain an approximation of the principal...
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...
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...
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...
Optimization of a Maintenance Station Network
This report is about a method for optimizing maintenance station and storage networks for maintenance of various traffic channels like streets, roads and sea channels. The results that...
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...
TRACS: A Tool for Track Infrastructure Management
TRACS (Total Right-of-way Analysis and Costing system) combines engineering models with life-cycle costing techniques to estimate track maintenance and renewal costs as a function of track...
Modeling the Traffic Flow Impacts of Rehabilitation Activity on Two-Lane Highways
Researchers at the Purdue University have been involved in developing techniques for predicting the operational impacts created by one-way traffic control. These techniques estimate average...
