Deterioration and Predictive Condition Modeling of Concrete Bridge Decks Based on Data from Periodic NDE Surveys
(American Society of Civil Engineers, 2019)A novel approach and program are developed for deterioration and predictive modeling of concrete bridge decks based on nondestructive evaluation (NDE) data. Through an iterative process—combined with data processing, bridge ... -
Statistical Modeling in Absence of System Specific Data: Exploratory Empirical Analysis for Prediction of Water Main Breaks
(American Society of Civil Engineers, 2019)The replacement of deteriorating distribution pipes is an important process for water utilities. It helps reduce capital spending on water main breaks and improves customer satisfaction. To assist with the development of ... -
Systematic Assessment of Nondestructive Evaluation Techniques for Post-Tensioning and Stay Cable Systems
(American Society of Civil Engineers, 2019)Nondestructive evaluation (NDE) can provide invaluable information about the condition of tendons in post-tensioned and cable-stayed bridges, which can facilitate preventative actions to mitigate further deterioration. To ... -
Development of Zonal-Specific Semivariograms for a Strategic RWIS Network Optimization: Case Study
(American Society of Civil Engineers, 2019)This paper presents a study aimed at developing zonal-specific semivariograms for zones with different climates using regionalized random variables for a strategic road weather information system (RWIS) network implementation ... -
Resilience Evaluation Framework for Integrated Civil Infrastructure–Community Systems under Seismic Hazard
(American Society of Civil Engineers, 2019)Seismic resilience of civil infrastructure systems is an essential property of modern communities. In this paper, an agent-based modeling framework to evaluate the seismic resilience of an integrated system consisting of ... -
Interdiction-Based Approaches to Identify Damage in Disrupted Critical Infrastructures with Dependencies
(American Society of Civil Engineers, 2019)In this paper, we consider a problem in which the decision maker only has access to outage reports from service receivers in critical infrastructures with dependencies among them, and our objective is to determine inspection ... -
How Spatial and Functional Dependencies between Operations and Infrastructure Leads to Resilient Recovery
(American Society of Civil Engineers, 2019)A fast recovery of infrastructure functioning is important to the well-being of residents and the economy following interruption or disaster. Assessing the chances of recovery, or creating plans to enable it, is difficult ... -
Automated Rust-Defect Detection of a Steel Bridge Using Aerial Multispectral Imagery
(American Society of Civil Engineers, 2019)Computer vision methods have the potential to detect rust defects in steel components of bridges. However, direct use of images collected by aerial means to identify such defects is currently difficult because of obstructions ... -
Seven-Layer Classification of Infrastructure to Improve Community Resilience to Disasters
(American Society of Civil Engineers, 2019)Community resilience to natural disasters depends to a large extent on the adequacy of infrastructure services provided through multidimensional interdependent systems during postdisaster recovery. In the aftermath of a ... -
Ex Post Evaluation of Economic Infrastructure Assets: Significance of Regional Heterogeneities in Australia
(American Society of Civil Engineers, 2019)The process of evaluation is pivotal for ensuring infrastructure assets meet the demands and needs of business and the wider community. An empirical ex post evaluation of the impact of regional heterogeneities for economic ... -

Factors Affecting the Accuracy and Variability of Pavement Surface Evaluations and Ratings
(American Society of Civil Engineers, 2019)This research identified factors influencing the accuracy and variability of pavement surface evaluations and ratings (PASER). Survey and PASER data obtained from workshop participants were used to develop statistical ... -
Relationships among Value-for-Money Drivers of Public–Private Partnership Infrastructure Projects
(American Society of Civil Engineers, 2019)Value-for-money (VFM) drivers and their interrelationships have large impacts on increasing the VFM of public–private partnership (PPP) projects. However, very few studies have explored the potential interrelationships ... -
Influence of Profile Specification on International Roughness Index
(American Society of Civil Engineers, 2019)This paper addressed an important question of selection of wheel path(s) for International Roughness Index (IRI) or Mean Roughness Index (MRI) estimation. Twenty-one IRI/MRI alternatives of wheel path position(s) (single ... -
Deep Learning for Critical Infrastructure Resilience
(American Society of Civil Engineers, 2019)Ensuring the resiliency of critical infrastructures is essential in modern society, but much of the deployed infrastructure has yet to fully leverage modern technical developments. This paper intersects two unique fields—deep ... -
Temporal Assessment of the Embodied Greenhouse Gas Emissions of a Toronto Streetcar Line
(American Society of Civil Engineers, 2019)Transportation greenhouse gas (GHG) emissions often account for the largest share of urban GHG emissions. Consequently, large-scale reductions in urban GHG emissions will not be possible without significant improvements ... -
Impact of Side Friction on Performance of Rural Highways in India
(American Society of Civil Engineers, 2019)Abutting land-use patterns always play an important role in the performance of a road section. Land use along rural highways in developing countries is significantly different from that in developed countries. Existence ... -
Scenario Planning Application in US Highway Transportation Industry
(American Society of Civil Engineers, 2019)This paper demonstrates how a combination of qualitative and quantitative approaches following the scenario planning methodology can be used to identify driving forces (drivers) that might influence the future of the ...
