Climate Change, Energy, Sustainability and Pavements


Book Description

Climate change, energy production and consumption, and the need to improve the sustainability of all aspects of human activity are key inter-related issues for which solutions must be found and implemented quickly and efficiently. To be successfully implemented, solutions must recognize the rapidly changing socio-techno-political environment and multi-dimensional constraints presented by today’s interconnected world. As part of this global effort, considerations of climate change impacts, energy demands, and incorporation of sustainability concepts have increasing importance in the design, construction, and maintenance of highway and airport pavement systems. To prepare the human capacity to develop and implement these solutions, many educators, policy-makers and practitioners have stressed the paramount importance of formally incorporating sustainability concepts in the civil engineering curriculum to educate and train future civil engineers well-equipped to address our current and future sustainability challenges. This book will prove a valuable resource in the hands of researchers, educators and future engineering leaders, most of whom will be working in multidisciplinary environments to address a host of next-generation sustainable transportation infrastructure challenges. "This book proposes a broad detailed overview of the actual scientific knowledge about pavements linked to climate change, energy and sustainability at the international level in an original multidimensional/multi-effects way. By the end, the reader will be aware of the whole global issues to care about for various pavement technical features around the world, among which the implications of modelling including data collection, challenging resources saving and infrastructures services optimisation. This is a complete and varied work, rare in the domain." Dr. Agnes Jullien Research Director Director of Environmental, Development, Safety and Eco-Design Laboratory (EASE) Department of Development, Mobility and Environment Ifsttar Centre de Nantes Cedex- France “An excellent compilation of latest developments in the field of sustainable pavements. The chapter topics have been carefully chosen and are very well-organized with the intention of equipping the reader with the state-of-the-art knowledge on all aspects of pavement sustainability. Topics covered include pavement Life Cycle Analysis (LCA), pervious pavements, cool pavements, photocatalytic pavements, energy harvesting pavements, etc. which will all be of significant interest to students, researchers, and practitioners of pavement engineering. This book will no doubt serve as an excellent reference on the topic of sustainable pavements.” Dr. Wei-Hsing Huang Editor-in-Chief of International Journal of Pavement Research and Technology (IJPRT) and Professor of Civil Engineering National Central University Taiwan

Summary and Recommendations of Recycled Materials in Roadside Safety Devices


Book Description

In response to the increased interest in the use of recycled materials such as plastics, rubber, paper, and glass, etc., the Texas Department of Transportation (TxDOT) sponsored project 0-1458, entitled "Recycled Materials in Roadside Safety Devices." The purpose of this project was to investigate and explore the use of recycled materials in roadside safety applications with the goal of product implementation. This report summarizes a three-phase research program intended to evaluate the use of recycled materials in roadside safety devices. In the first phase, information regarding recycled material manufacturers and their products was acquired through an extensive literature review and survey of research organizations, state and federal transportation agencies, professional and trade societies, and manufacturers. In the second phase of this project, products were further evaluated through a series of static and dynamic laboratory tests. The testing focused on the applications of Type III barricades, guardrail posts, guardrail offset blocks, and sign supports which were identified as areas with high potential that lacked suitable recycled alternatives. The products showed a wide range in behavior due to different material compositions. Phase III consisted of full-scale crash testing of selected products to validate laboratory results, verify their crashworthiness, and assist with the development of performance specifications. Three products were evaluated for use as temporary sign supports. Another product was evaluated for use as guardrail posts and offset blocks in strong post W-beam guardrail. Performance specifications were prepared for these applications and are included as appendices in the summary report




Sustainability Issues in Civil Engineering


Book Description

This compilation on sustainability issues in civil engineering comprises contributions from international experts who have been working in the area of sustainability in civil engineering. Many of the contributions have been presented as keynote lectures at the International Conference on Sustainable Civil Infrastructure (ICSCI) held in Hyderabad, India. The book has been divided into core themes of Sustainable Transportation Systems, Sustainable Geosystems, Sustainable Environmental and Water Resources and Sustainable Structural Systems. Use of sustainability principles in engineering has become an important component of the process of design and in this context, design and analysis approaches in civil engineering are being reexamined to incorporate the principles of sustainable designs and construction in practice. Developing economies are on the threshold of rapid infrastructure growth and there is a need to compile the developments in various branches of civil engineering and highlight the issues. It is this need that prompted the composition of this book. The contents of this book will be useful to students, professionals, and researchers working on sustainability related problems in civil engineering. The book also provides a perspective on sustainability for practicing civil engineers who are not directly researching the problems but are affected by the concerns in the course of their profession. The book can also serve to highlight to policy makers and governing bodies the need to have a mandate for sustainable infrastructural development.
