Pavement Life-Cycle Assessment


Book Description

An increasing number of agencies, academic institutes, and governmental and industrial bodies are embracing the principles of sustainability in managing their activities and conducting business. Pavement Life-Cycle Assessment contains contributions to the Pavement Life-Cycle Assessment Symposium 2017 (Champaign, IL, USA, 12-13 April 2017) and discusses the current status of as well as future developments for LCA implementation in project- and network-level applications. The papers cover a wide variety of topics: - Recent developments for the regional inventory databases for materials, construction, and maintenance and rehabilitation life-cycle stages and critical challenges - Review of methodological choices and impact on LCA results - Use of LCA in decision making for project selection - Implementation of case studies and lessons learned: agency perspectives - Integration of LCA into pavement management systems (PMS) - Project-level LCA implementation case studies - Network-level LCA applications and critical challenges - Use-phase rolling resistance models and field validation - Uncertainty assessment in all life-cycle stages - Role of PCR and EPDs in the implementation of LCA Pavement Life-Cycle Assessment will be of interest to academics, professionals, and policymakers involved or interested in Highway and Airport Pavements.







Life-cycle Cost Analysis in Pavement Design


Book Description

This Interim Technical Bulletin recommends procedures for conducting Life-Cycle Cost Analysis (LCCA) of pavements, provides detailed procedures to determine work zone user costs, and introduces a probabilistic approach to account for the uncertainty associated with LCCA inputs.




Sustainability Guidelines for the Structural Engineer


Book Description

The Sustainability Committee of the American Society of Civil Engineer s Structural Engineering Institute (ASCE SEI) prepared these guidelines to advance the understanding of sustainability in the structural community and to incorporate concepts of sustainability into structural engineering standards and practices. This book will educate and guide structural engineers as they meet the challenge to design and construct a sustainable built environment. The guidelines are organized into five sections: Sustainable Design and Construction, Sustainable Strategies, Building Materials, Infrastructure, and Case Studies. Although many of the subjects presented are related, each section and the related subsections have been written to stand alone, allowing this report to be used as a practical reference. This report was written for structural engineers, but related disciplines will also benefit from the contents. The book includes an important section on infrastructure because, many of the concepts and ideas presented in this guide relate to infrastructure, as well as design and construction.




Pavement, Roadway, and Bridge Life Cycle Assessment 2020


Book Description

An increasing number of agencies, academic institutes, and governmental and industrial bodies are embracing the principles of sustainability in managing their activities. Life Cycle Assessment (LCA) is an approach developed to provide decision support regarding the environmental impact of industrial processes and products. LCA is a field with ongoing research, development and improvement and is being implemented world-wide, particularly in the areas of pavement, roadways and bridges. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 contains the contributions to the International Symposium on Pavement, Roadway, and Bridge Life Cycle Assessment 2020 (Davis, CA, USA, June 3-6, 2020) covering research and practical issues related to pavement, roadway and bridge LCA, including data and tools, asset management, environmental product declarations, procurement, planning, vehicle interaction, and impact of materials, structure, and construction. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 will be of interest to researchers, professionals, and policymakers in academia, industry, and government who are interested in the sustainability of pavements, roadways and bridges.




Application of Probabilistic Life Cycle Cost Analysis in Pavement Management


Book Description

Transportation agencies seek to optimize their public budget to finance the construction and maintenance of pavements. Life Cycle Cost Analysis (LCCA) is a decision support tool that allows agencies to contrast and optimize infrastructure design alternatives based on the costs of the asset over its lifetime. In this thesis, statistical distributions were developed to study the variability associated with LCCA inputs based on agency historical data of the Province of Manitoba and the City of Winnipeg. A case study was used to compare the deterministic and the probabilistic computational approaches results. The results demonstrated that a probabilistic LCCA provides reliability levels for the evaluation of the total project cost, which allows for analyzing the risk associated with each alternative and avoiding cost overruns. It is recommended that transportation agencies consider probabilistic LCCA as part of their decision-making process due to the economic benefits and reliability levels that this approach provides.




Life Cycle Cost Analysis


Book Description

Life-cycle cost analysis (LCCA) is an engineering economic analysis tool useful in comparing the relative merit of competing pavement design alternatives. The Pennsylvania Department of Transportation shares their experience with LCCA.
