Plastic Waste For Sustainable Asphalt Roads

Waste polymers have been studied for various applications such as energy generation and biochemical production; however, their application in asphalt roads still poses some questions. Over the last decade, several studies have reported the utilization of waste plastics in roads using different methodologies and raw materials, but there is still significant inconsistency around this topic. What is the right methodology to recycle waste plastics for road applications? What is the correct type of waste plastics to be used in road applications? What environmental concerns could arise from the use of waste plastics in road applications? Plastic Waste for Sustainable Asphalt Roads covers the various processes and techniques for the utilization of waste plastics in asphalt mixes. The book discusses the various material properties and methodologies, effects of various methodologies, and combination of various polymers. It also provides information on the compatibility between bitumen and plastics, final asphalt performance, and environmental challenges. Discusses the processes and techniques for utilization of waste plastics in asphalt mixes. Features a life-cycle assessment of waste plastics in road surfaces and possible Environmental Product Declarations (EPD). Includes examples of on-field usage through various case studies.

This book considers the application of recycled materials both in pavement and geotechnical engineering. Currently, Australia has faced the fundamental concern of recycling waste plastic. On 1 January 2018, China enforced a prohibition on the importation of waste plastic. China's ban is followed by other countries like India, Indonesia, and Malaysia. The ban caused many corporations to abandon waste collection agreements, and the stockpiling of waste, as there is nowhere to safely deposit this waste. This issue seems, to a great extent, to have placed Australia's recycling industry in a crisis. As a result, local councils will have to find strategic ways of recycling accumulated waste that will become a more significant issue in the coming years. In Australia, apart from economic growth, the road pavement has weakened rapidly as the current pavement unable to withstand this urgent traffic load demand. The adding of polymers to the mixtures improves the stiffness, rutting resistance, and fatigue cracking [1]. However, the application of virgin polymer is costly. Thus, using waste polymer such as waste plastic polymer is an inexpensive substitute. The potential for recycled plastic to improve the performance properties of asphalt mixtures has been demonstrated in many countries the UK, Canada, The Netherlands, and India [2]. Similarly, another application of recycled materials can be in geotechnical infrastructure. This book considers the application of recycled materials both in pavement and geotechnical engineering.

Roads and Airports Pavement Surface Characteristics contains the papers presented at the 9th International Symposium on Pavement Surface Characteristics (SURF 2022, Milan, Italy, 12-14 September 2022). The symposium was jointly organized by the Italian company that manages Italy’s National Roads (ANAS –Ferrovie dello Stato Italiane Group), the World Road Association (PIARC) and Politecnico di Milano. The contributions aim to improve the quality of pavement surface characteristics while accomplishing efficiency, safety, sustainability, and addressing new generation mobility needs. The book covers topics from emerging research to engineering practice, and is divided in the following sections: Advanced and performing construction methods and equipment Next generation mobility Data monitoring and performance assessment Surface features and performances| Maintenance and preservation treatments Pavement management Economic and political strategies Safety and risk issues Minimizing road impacts Sustainability and performances issues about materials and design Pavements surfaces and urban heat islands Weather conditions impact Airport pavements Roads and Airports Pavement Surface Characteristics is of interest to academics, engineers and professionals in the fields of pavement engineering, transport infrastructure, and related disciplines.

Plastic pollution is a complex environmental problem. The use of recycled plastics in the modification of concrete materials has a dominant role to play in the move towards sustainable construction. Reuse of Plastic Waste in Eco-efficient Concrete presents the latest research findings on the application and use of recycled plastic waste in sustainable construction. Divided over four parts, the chapters cover various techniques for processing and separation of plastic wastes; use of recycled plastics as aggregates in modified concrete; as well as lightweight reinforced concrete applications too. There is also an entire section dedicated to asphalt mixtures. The book provides technological solutions on how recycled plastic wastes can be applied in concrete manufacturing. It will be a valuable reference source for academic and industrial researchers who are working with waste materials and the use of recycled plastics in concrete, as well as for civil and structural engineers, polymer production technologists, and concrete manufacturers. Describes the main types of recycled plastics that can be applied in concrete manufacturing Presents, state-of-the art knowledge on the properties of conventional concrete with recycled plastics Discusses the technological challenges for concrete manufacturers for mass production of recycled concrete from plastic waste Covers lifecycle cost analysis, production challenges, and long-term performance analysis

The affluence of western society has given rise to unprecedented quantities of waste, presenting one of the most intractable environmental problems for contemporary society. This book examines recycling and municipal waste management in three major cities: London, New York and Hamburg. A range of political and economic issues are examined to illustrate how any reduction in the size of the waste stream in order to achieve more equitable and environmentally sustainable patterns of resource use is incompatible with the current emphasis in the use of the market for environmental protection. The case studies show how, contrary to the hopes of many environmentalists and policy makers, municipal waste management is moving steadily towards the profitable option of incineration with energy recovery, rather than the recycling of materials or waste reduction at source. The evidence suggests that the achievement of a more sustainable pattern of recycling and waste management policy would demand a fundamental change in public policy, to give government a more active role in environmental protection.

This book presents the work of the RILEM TC 279-WMR, whose purpose was to facilitate the use of waste, marginal and secondary materials for roads by investigating the performance of road materials containing waste through round robin tests and the development of standard procedures for their selection, preparation, and use. The structure of this book includes an introduction, five technical chapters, and a conclusion. The topics addressed are: the use of asphalt binder additives such as plastic and rubber; the combined use of aggregate and filler substitute in paving mixtures (construction demolition waste, rubber, and steel slags); the environmental assessment and the potential sources of pollutants originated from the use of this recycled materials.
