Book Description
The main objective of this research was to evaluate characteristics of milled Recycled Asphalt Pavements (RAP) collected from selected milled roadways in Kansas. The RAP was collected from three selected milled roadways including K-25 in Grant County, K-25 in Logan County, and US-83 in Scott County. The aggregates were extracted from RAP, and tested for characteristics including gradation, specific gravity, Fine Aggregate Angularity (FAA), Coarse Aggregate Angularity (CAA), flat and elongation (F & E), and Los Angeles Abrasion (LA) values. Binder from each source was extracted from the RAP, and recovered for a PG grade testing. The changes in the properties of aggregates after milling from the roadways as compared with the original aggregates are discussed. The variability of RAP aggregates was analyzed. In addition, the differences between the properties of aggregates extracted by centrifuge and ignition methods are compared.

Book Description
This volume highlights the latest advances, innovations, and applications in the field of asphalt pavement technology, as presented by leading international researchers and engineers at the 5th International Symposium on Asphalt Pavements & Environment (ISAP 2019 APE Symposium), held in Padua, Italy on September 11-13, 2019. It covers a diverse range of topics concerning materials and technologies for asphalt pavements, designed for sustainability and environmental compatibility: sustainable pavement materials, marginal materials for asphalt pavements, pavement structures, testing methods and performance, maintenance and management methods, urban heat island mitigation, energy harvesting, and Life Cycle Assessment. The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster multidisciplinary collaboration among different specialists.

Book Description
Functional Pavement Design is a collections of 186 papers from 27 different countries, which were presented at the 4th Chinese-European Workshops (CEW) on Functional Pavement Design (Delft, the Netherlands, 29 June-1 July 2016). The focus of the CEW series is on field tests, laboratory test methods and advanced analysis techniques, and cover analysis, material development and production, experimental characterization, design and construction of pavements. The main areas covered by the book include: - Flexible pavements - Pavement and bitumen - Pavement performance and LCCA - Pavement structures - Pavements and environment - Pavements and innovation - Rigid pavements - Safety - Traffic engineering Functional Pavement Design is for contributing to the establishment of a new generation of pavement design methodologies in which rational mechanics principles, advanced constitutive models and advanced material characterization techniques shall constitute the backbone of the design process. The book will be much of interest to professionals and academics in pavement engineering and related disciplines.

Book Description
The Routledge Handbook of the Extractive Industries and Sustainable Development provides a cutting-edge, comprehensive overview of current trends, challenges and opportunities for metal and mineral production and use, in the context of climate change and the United Nations Sustainable Development Agenda 2030. Minerals and metals are used throughout the world in manufacturing, construction, infrastructure, production of electronics and consumer goods. Alongside this widespread use, extraction and processing of mineral resources take place in almost every nation at varying scales, both in developing countries and major developed nations. The chapters in this interdisciplinary handbook examine the international governance mechanisms regulating social, environmental and economic implications of mineral resource extraction and use. The original contributions, from a range of scholars, examine the relevance of the mining industry to the United Nations Sustainable Development Goals (SDGs), reviewing important themes such as local communities Indigenous peoples, gender equality and fair trade, showing how mining can influence global sustainable development. The chapters are organised into three sections: Global Trends in Mineral Resources Consumption and Production; Technology, Minerals and Sustainable Development; and Management of Social, Environmental and Economic Issues in the Mining Industry. This handbook will serve as an important resource for students and researchers of geology, geography, earth science, environmental studies, engineering, international development, sustainable development and business management, among others. It will also be of interest to professionals in governmental, international and non-governmental organisations that are working on issues of resource governance, environmental protection and social justice.

Book Description
Recycling of aged asphalt concrete pavements has been demonstrated to be cost-effective and to reduce the demand for natural resources such as aggregate and asphalt. Because of the advantages derived when using recycled materials, the capability to predict long-term performance is needed so that optimum benefits can be obtained. This study was undertaken to evaluate the laboratory performance to recycled asphalt concrete mixtures and to compare these results to those measured for conventional asphalt concrete mixtures. Results of this study indicated a satisfactory comparison between laboratory performance of recycled mixtures and conventional mixtures. Fatigue analysis indicated that conventional mixtures would provide the greatest fatigue resistance in thick asphalt concrete layers at lower temperatures, while the recycled mixtures would provide the greatest fatigue resistance in thin asphalt layers at higher temperatures. Water susceptability was shown to be related more to aggregate type than to mixture type. The data show that recycled mixtures prepared with the recycling agent produced mixtures with the lowest durability and poorest low temperature performance when compared with the recycled mixtures prepared with AC-5 or compared with the conventional mixtures.

Book Description
Scientific management strategies can help in exploring anthropogenic wastes (human-made materials) as potential resources through the urban mining concept and be a panacea for sustainable development. This book covers five broader aspects of waste management and resource recovery in urban mining including solid and liquid waste management and treatment. It explains sustainable approaches of urban mining for the effective management of solid and liquid wastes and facilitates their conversion into secondary resources. Overall, this book provides details of urban mining and its different applications including current waste management problems, practices, and challenges faced worldwide. Presents a holistic approach for urban mining considering various types of wastes Describes contemporary integrated approaches for waste management with specific case studies Provides technical, social, and environmental aspects of solid and liquid wastes Considers aspects of sustainability and a circular bio-economy Incorporates pertinent case studies on water and wastewater management This volume caters to researchers and graduate students in environmental engineering, solid waste management, wastewater treatment, and materials science.

Book Description
This unique book brings together high-quality research contributions on ecological aspects of urbanization, water quality concerns in an urban environment, and climate change issues with a strong Indian focus under one umbrella. It includes several case studies that discuss urban water management, particularly highlighting the quality aspects. Urbanization is an ecological disturbance that the modern world accepts as essential in the absence of a better alternative that could provide an equal level of comfort. The prohibitive costs of eco-friendly production technologies are forcing the developing world to generate industrial waste that is detrimental to the environment. At the same time, the availability of adequate fresh water is another challenge for our climate-change impacted world. The scientific community is, therefore, searching for ways towards ecologically sustainable urban development. Discussing all these issues, this book offers a useful guide for academicians, researchers, practicing engineers, and managers dealing with diverse water-related problems in urban areas.
