Dimensions of Wastewater System Recovery Following Major Disruptions
(American Society of Civil Engineers, 2017)Following a major disaster or disruption, the restoration of infrastructure function is often tracked over time. For a more detailed understanding of the recovery process, this paper separates wastewater recovery into ... -
Detection of Bridge-Deck Delamination Using Full Ultrasonic Waveform Tomography
(American Society of Civil Engineers, 2017)A two-dimensional (2D) time-domain waveform tomography technique is presented for detection of delamination in concrete bridge decks. Measured ultrasonic surface wave fields were inverted using a full waveform inversion ... -
LFRD Calibration of Pullout Resistance Factors Using Survival Analysis for Soil Nails in North Texas
(American Society of Civil Engineers, 2016)Reliability-based analysis of the calibration of pullout resistance factors (φPO) for soil nails are presented in this paper. To conduct the calibration, a total of 47 verification tests conducted in cohesive soil within ... -
Risk-Cost Optimization of Buried Pipelines Using Subset Simulation
(American Society of Civil Engineers, 2016)On the basis of time-dependent reliability analysis, a computational framework called subset simulation (SS) has been applied for risk-cost optimization of flexible underground pipeline networks. SS can provide better ... -
Semi-Markov Models for the Deterioration of Bridge Elements
(American Society of Civil Engineers, 2016)Many bridge management systems (BMSs) use a Markov chain model to forecast the deterioration process. The Markov property may be considered to be restrictive when modeling the deterioration of transportation assets, primarily ... -
Erratum for “Evaluating Flexibility in Water Distribution System Design under Future Demand Uncertainty” by Innocent Basupi and Zoran Kapelan
(American Society of Civil Engineers, 2016) -
Cost–Benefit Analysis and Microclimate-Based Optimization of a RWIS Network
(American Society of Civil Engineers, 2016)The Road Weather Information System (RWIS) has been applied as an effective tool to collect weather and road surface temperature information and to assist operational decisions for snow and ice control activities. Current ... -
An Integrated Productivity-Practices Implementation Index for Planning the Execution of Infrastructure Projects
(American Society of Civil Engineers, 2016)Productivity and project performance can be improved through implementing best practices. This paper describes the development of a best productivity practices implementation index (BPPII) for infrastructure projects. The ... -
Utility Management System Cost and Time Benefits and Implications from the Local Agency Perspective
(American Society of Civil Engineers, 2016)Utility management systems (UMSs) have become more common for government agencies, and their use has recently been advocated by AASHTO on a statewide basis. By identifying current utility locations and correlating ... -
Vulnerability of Infrastructure Systems: Macroscopic Analysis of Critical Disruptions on Road Networks
(American Society of Civil Engineers, 2016)Networked infrastructures serve as essential backbones of society. In particular, road transportation networks have a principal role in people’s everyday lives because they facilitate physical connectivity. External factors, ... -
Modeling of Risks Threatening Critical Infrastructures: System Approach
(American Society of Civil Engineers, 2016)The objective of this paper is to model interconnectivities among systems and subsystems of transport and critical infrastructures vulnerable to climatic events that impose the highest impacts on people and regional economies ... -
Use of Aluminum Residue and Recycled Asphalt Pavement Materials to Stabilize Silty Clay Soil
(American Society of Civil Engineers, 2016)The effectiveness of mixing aluminum residue and recycled asphalt pavement materials (RAPs) with silty clay soil on the soil’s physical properties was discussed. The mixing material that is used enhances the silty clay ... -
Effect of through Crack Size on Strength of Shell Structures
(American Society of Civil Engineers, 2016)The analysis of numerous cases of failure in shell structures has shown it occurs at stresses lower than the design stresses. The origin of these failures has been attributable to flaws or cracks. To determine which size ... -

Using Count Data to Model Infrastructure Distress Initiation and Progression
(American Society of Civil Engineers, 2015)Transportation infrastructure condition (or distress) can be modeled as continuous or discrete variables. As discrete variables, they are commonly recorded with nonnegative integers. In deterioration models, these variables ... -
Winter Road Surface Condition Forecasting
(American Society of Civil Engineers, 2015)This study has attempted to address a challenging problem in winter road maintenance, namely road surface condition (RSC) forecasting. A novel conceptual framework for short-term road surface condition forecasting is ... -
