Acoustic Tomographic Imaging of Concrete Infrastructure
(American Society of Civil Engineers, 2000)Acoustic tomography is an established nondestructive evaluation (NDE) technology that can be used to image the interior of large grained building materials such as concrete or masonry. A literature search focusing on ... -
Designs and Implementations of Automated Systems for Pavement Surface Distress Survey
(American Society of Civil Engineers, 2000)The categorization and quantification of the type, severity, and extent of surface distress is a primary method for assessing the condition of highway pavements. Various methodologies were developed to automate pavement ... -
Externally Bonded FRP for Service-Life Extension of RC Infrastructure
(American Society of Civil Engineers, 2000)Although the concept of repairing and strengthening reinforced concrete (RC) structures using steel plate reinforcement has been established for more than 30 years, today there is an increasing trend toward the use of ... -
Optimal Life-Cycle Costing with Partial Observability
(American Society of Civil Engineers, 2000)Optimal costing of structures requires taking into account lifetime management (inspection and maintenance) costs in addition to initial construction cost. Recently published papers on lifetime costing have used Markov ... -
Condition Assessment of Water Supply Infrastructure
(American Society of Civil Engineers, 1999) -
Cost/Benefits of Robotics in Infrastructure and Environmental Renewal
(American Society of Civil Engineers, 2000)Robotic systems have become common in many manufacturing and production operations because they have proven to be more robust, safe, efficient, accurate, and productive than the processes they replaced. These same attributes ... -
Research Needs for Engineering Aspects of Natural Disasters
(American Society of Civil Engineers, 2000)Engineering research needs related to the second national assessment of future directions of research and applications for more sustainable natural disaster management are presented. The evolution of codes and practice in ... -
TDR Monitoring for Integrity of Structural Systems
(American Society of Civil Engineers, 2000)Most infrastructures are made up of large number of parts, such as truss members and bridge decks. Relative movement of the connections between members causes load redistribution or even failure. Monitoring the integrity ... -
Dielectric Constant and Relaxation Time of Asphalt Pavement Materials
(American Society of Civil Engineers, 1999)The static dielectric constant and relaxation time of two asphalt aggregate mixes commonly used as the bearing and wearing courses of asphalt pavements are measured in the frequency range of 0.1 MHz to 1.5 GHz. The measurement ... -
Disaggregation of Environmental Factors Affecting Sewer Pipe Failures
(American Society of Civil Engineers, 1999)This paper documents the development, calibration, and evaluation of a novel simulation model for understanding and predicting failures of wastewater pipe systems. The model is presented and subsequently calibrated and ... -
Sample Size Analysis for Asphalt Pavement Quality Control
(American Society of Civil Engineers, 1999)A review of the quality assurance practices of Alberta Transportation & Utilities was undertaken for each of three quality test measures: (1) Asphalt content; (2) percent compaction; and (3) aggregate gradation. The primary ... -
Optimization of Infrastructure Systems Maintenance and Improvement Policies
(American Society of Civil Engineers, 1999)This paper presents an approach for the joint optimization of maintenance and improvements of the components of a network of infrastructure facilities. In the literature, these two problems have often been handled separately, ... -
Risk Analysis of Traffic and Revenue Forecasts for Road Investment Projects
(American Society of Civil Engineers, 1999) -
Structural Design Considerations in House Builders' Model: Optimization Approach
(American Society of Civil Engineers, 1999)In a housing market model, the supply of housing, particularly new houses, is usually treated in a very cursory fashion, with new housing being regarded as homogeneously good and building cost function defined as a function ... -
Saint Paul Public Works Management
(American Society of Civil Engineers, 1999) -
Sensitivity of Long-Term Infrastructure Condition to Initial Quality
(American Society of Civil Engineers, 1999)Infrastructure condition throughout the lifetime of a facility is in part influenced by factors that are decided upon during initial design and construction. This paper presents a framework for exploring the sensitivity ... -
Prioritizing Scour Vulnerable Bridges Using Risk
(American Society of Civil Engineers, 1999)The purpose of this study is to develop a method for assessing the risk associated with scour threat to bridge foundations. In response to numerous scour-related bridge failures, the Federal Highway Administration has ... -
Diagnostic Techniques for Sewer Systems
(American Society of Civil Engineers, 1999)The National Research Council Canada has recently completed a project to assist the city of Montreal in determining the condition of its water and sewer system. The National Research Council Canada staff members reviewed ... -
Deep Mixing Technology for Liquefaction Mitigation
(American Society of Civil Engineers, 1999)The emergence of new technologies is largely dependent on critical examination of the current state of relevant technologies. Accordingly, this paper aims to present the latest advancements in the issues related to deep ... -
