Importance of Sustainability-Related Cost Components in Highway Infrastructure: Perspective of Stakeholders in Australia
(American Society of Civil Engineers, 2014)Highway infrastructure development typically requires major capital input. Unless planned properly, such requirements can cause serious financial constraints for investors. The push for sustainability adds a new dimension ... -
Comparative Study of Three Stochastic Models for Prediction of Pipe Failures in Water Supply Systems
(American Society of Civil Engineers, 2013)The prediction of pipe failures in urban water systems is a complex process because the available failure records, originating in work orders, are often short and incomplete. To identify a robust and simple model with good ... -
Quantifying End-Use Energy Intensity of the Urban Water Cycle
(American Society of Civil Engineers, 2013)The water end-use segment (WES), consisting of activities that utilize water in homes and buildings, has been identified as a major component of energy use in the urban water supply system. In this paper, an analytical ... -
Management of Civil Infrastructure Systems: QFD-Based Approach
(American Society of Civil Engineers, 2014)Infrastructure owners or management agencies have well established quality control programs with the intent of achieving safe and effective maintenance. However, consumers are becoming more involved in economic, environmental, ... -
Simultaneous Network Optimization Approach for Pavement Management Systems
(American Society of Civil Engineers, 2014)In the context of sequential decision making under uncertainty, the Markov decision process (MDP) is a widely used mathematical framework. The MDP-based approaches in the infrastructure management literature can be broadly ... -
Discussion of “Implementation of LRFD of Drilled Shafts in Louisiana” by Xinbao Yu, Murad Y. Abu-Farsakh, Sungmin Yoon, Ching Tsai, and Zhongjie Zhang

Cost-Estimating Model for Rubberized Asphalt Pavement Rehabilitation Projects
(American Society of Civil Engineers, 2013)There are nearly 4,800,000 km (3,000,000 miles) of paved roads and 80,000 km (50,000 miles) of paved highways in the United States, many of which are in poor condition and approaching the end of their design life. To upgrade ... -
Applying Multiobjective Bilevel Optimization under Fuzzy Random Environment to Traffic Assignment Problem: Case Study of a Large-Scale Construction Project
(American Society of Civil Engineers, 2014)This article presents an optimization method for solving a material flow traffic assignment problem (TAP) in a large-scale construction project considering a hierarchical structure with fuzzy random variables. A multiobjective ... -
Alternative to Government Revenue Guarantees: Dynamic Revenue Insurance Contracts
(American Society of Civil Engineers, 2013)Public private partnerships (PPPs) are arrangements under which the private sector supplies infrastructure assets and services that traditionally have been provided by the public sector. Public authorities may enhance the ... -
Estimation of Pavement Crack Initiation Models by Combining Experimental and Field Data
(American Society of Civil Engineers, 2013)Development of deterioration models for pavements is an essential part of maintenance and rehabilitation planning. Often, when pavement-deterioration models are developed for developing countries or states that do not have ... -
Risk-Informed Investment for Tropical Cyclone Preparedness of Highway Signs, Signals, and Lights
(American Society of Civil Engineers, 2013)Transportation corridors at regional and national scales are vulnerable to region-wide natural disasters resulting from tropical cyclones, including tropical storms and hurricanes. In addition to floods and debris causing ... -
Using Classification Trees for Predicting National Bridge Inventory Condition Ratings
(American Society of Civil Engineers, 2013)In bridge management practice, bridge condition is the fundamental information needed to allow decision makers to make well-informed decisions regarding preservation, rehabilitation, or replacement of a bridge or network ... -
Simulation Model to Prioritize Right-of-Way Acquisitions
(American Society of Civil Engineers, 2014)The costs involved in right-of-way (ROW) acquisition are rapidly increasing, making it more difficult for agencies to complete projects on time and budget. When funds are constrained, the question of what parcels should ... -
Leveling Process of Annual Budgetary Requirements for Pavement Preservation
(American Society of Civil Engineers, 2014)This paper presents a model for leveling annual budgetary requirements (ABRs) for pavement preservation programs over a multiyear analysis period. Given the information such as the candidate pavement preservation projects, ... -
Public-Private Partnerships: Capital Market Conditions and Alternative Finance Mechanisms for Australian Infrastructure Projects
(American Society of Civil Engineers, 2013)The impact of the prevailing capital markets on public-private partnerships and their future use in the medium term in Australia are examined. Alternative finance mechanisms that can be used by Australian state governments ... -
Sustainability of Natural Hazard Risk Mitigation: Life Cycle Analysis of Environmental Indicators for Bridge Infrastructure
(American Society of Civil Engineers, 2013)The performance of structures and infrastructure under natural hazards can have a significant impact on the sustainability of the system, often characterized in terms of environmental, economic, or social indicators of ... -

Neural Network Approach to Condition Assessment of Highway Culverts: Case Study in Ohio
(American Society of Civil Engineers, 2013)Millions of culverts exist in the United States, and they are aging rapidly. Inspection of all the culverts consumes a lot of time and resources. Instead of inspecting each culvert every 5 years, this study presents a more ... -
External and Internal Corrosion of Large-Diameter Cast Iron Mains
(American Society of Civil Engineers, 2013)Deterioration in cast iron mains manifests itself in the form of corrosion. External corrosion is typically found to occur in pipes buried in corrosive soils while internal corrosion is dependent on water chemistry and ... -
Assessment of Risk Using Bridge Element Condition Ratings
(American Society of Civil Engineers, 2013)In this paper, a methodology for quantifying lifetime risk of bridge superstructures is presented. The risk is quantified in terms of the expected direct and indirect losses. A scenario-based approach, which uses the
