Life-cycle Cost Analysis in Pavement Design by James Walls Pdf
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.
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.
Pavement, Roadway, and Bridge Life Cycle Assessment 2020 by John Harvey,Imad L. Al-Qadi,Hasan Ozer,Gerardo Flintsch Pdf
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.

Life Cycle Cost Analysis for INDOT Pavement Design Procedures by Geoffry Lamptey,Muhammad Z. Ahmad,Samuel Labi Pdf
Given the aging of highway pavements, high traffic levels, and uncertainty of sustained preservation funding, there is a need for balanced decision-making tools such as LCCA to ensure long-term and cost-effective pavement investments. It has been shown in past research that more effective long-term pavement investment could be made at lower cost using LCCA. Current LCCA-based pavement design and preservation practice in Indiana could be further enhanced by due consideration of user costs. Also, the existing FHWA LCCA software could be further enhanced for increased versatility, flexibility, and more specific applicability to the needs of Indiana, particularly with regard to treatment cost estimation and development of alternative feasible preservation strategies (rehabilitation and maintenance types and timings). The study documented/developed several sets of alternative pavement design and preservation strategies consistent with existing and foreseen Indiana practice. The preservation strategies were developed using two alternative criteria – trigger values (pavement condition thresholds) and predefined time intervals (based on treatment service lives) and are intended for further study before they can be used for practice. These strategies were developed on the basis of historical pavement management data, existing INDOT Design Manual standards, and a survey of experts. The study also found that with a few enhancements, FHWA’s current LCCA methodology and software (RealCost) could be adapted for use by INDOT for purposes of decision support for pavement investments and proceeded to make such enhancements.
Life Cycle Cost Analysis State-of-the-practice by Jay Goldbaum Pdf
This report provides an outline for the engineer seeking to conduct a Life-Cycle Cost Analysis (LCCA) in pavement design and selection. The guidance, recommendations, and default values provided here were collected from 10 years of paving projects. Most of these projects were constructed or rehabilitated in the mid 1980s in order to evaluate the current design and construction practices in the State of Colorado. At this time, the Colorado Department of Transportation uses a deterministic approach to the LCCA and is researching the move toward a probabilistic LCCA.
Proceedings of the 9th International Conference on Maintenance and Rehabilitation of Pavements—Mairepav9 by Christiane Raab Pdf
This book gathers the proceedings of an international conference held at Empa (Swiss Federal Laboratories for materials Science and Technology) in Dübendorf, Switzerland, in July 2020. The conference series was established by the International Society of Maintenance and Rehabilitation of Transport Infrastructure (iSMARTi) for promoting and discussing state-of-the-art design, maintenance, rehabilitation and management of pavements. The inaugural conference was held at Mackenzie Presbyterian University in Sao Paulo, Brazil, in 2000. The series has steadily grown over the past 20 years, with installments hosted in various countries all over the world. The respective contributions share the latest insights from research and practice in the maintenance and rehabilitation of pavements, and discuss advanced materials, technologies and solutions for achieving an even more sustainable and environmentally friendly infrastructure.
Pavement Life-Cycle Assessment by Imad L. Al-Qadi,Hasan Ozer,John Harvey Pdf
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.
