Asphalt Materials Science And Technology

Asphalt is a complex but popular civil engineering material. Design engineers must understand these complexities in order to optimize its use. Whether or not it is used to pave a busy highway, waterproof a rooftop or smooth out an airport runway, Asphalt Materials Science and Technology acquaints engineers with the issues and technologies surrounding the proper selection and uses of asphalts. With this book in hand, researchers and engineering will find a valuable guide to the production, use and environmental aspect of asphalt. Covers the Nomenclature and Terminology for Asphalt including: Performance Graded (PG) Binders, Asphalt Cement (AC), Asphalt-Rubber (A-R) Binder, Asphalt Emulsion and Cutback Asphalt Includes Material Selection Considerations, Testing, and applications Biodegradation of Asphalt and environmental aspects of asphalt use

Asphalt is a semi-solid, black and sticky form of petroleum which is also known as bitumen. It may be found in natural deposits or it could be a refined product called pitch. Pitch is derived from petroleum, coal, plants and tar or it is manufactured. Asphalt is primarily used in road constructions as a binder or glue that is mixed with aggregate particles such as sand, gravel, recycled concrete and crushed stones to create asphalt concrete. The other main uses of asphalt include bituminous waterproofing systems that are designed to protect the commercial and residential buildings from water. This book includes some of the vital pieces of work being conducted across the world, on various topics related to asphalt material. Most of the topics introduced in this book cover new techniques and the applications of such material. It will provide comprehensive knowledge to the readers.

"Offers comprehensive, authoritative coverage of the chemistry, technology, and engineering of asphaltic products for paving, road construction, roofing, coatings, adhesives, and batteries. Analyzes microcracking and elucidates the mechanisms of degradation to aid the development of hot melt asphalt and increase longevity."

This book is a printed edition of the Special Issue "Advanced Asphalt Materials and Paving Technologies" that was published in Applied Sciences

The urgent need for infrastructure rehabilitation and maintenance has led to a rise in the levels of research into bituminous materials. Breakthroughs in sustainable and environmentally friendly bituminous materials are certain to have a significant impact on national economies and energy sustainability. This book will provide a comprehensive review on recent advances in research and technological developments in bituminous materials. Opening with an introductory chapter on asphalt materials and a section on the perspective of bituminous binder specifications, Part One covers the physiochemical characterisation and analysis of asphalt materials. Part Two reviews the range of distress (damage) mechanisms in asphalt materials, with chapters covering cracking, deformation, fatigue cracking and healing of asphalt mixtures, as well as moisture damage and the multiscale oxidative aging modelling approach for asphalt concrete. The final section of this book investigates alternative asphalt materials. Chapters within this section review such aspects as alternative binders for asphalt pavements such as bio binders and RAP, paving with asphalt emulsions and aggregate grading optimization. Provides an insight into advances and techniques for bituminous materials Comprehensively reviews the physicochemical characteristics of bituminous materials Investigate asphalt materials on the nano-scale, including how RAP/RAS materials can be recycled and how asphalt materials can self-heal and rejuvenator selection

This book discusses the applications of fracture mechanics in the design and maintenance of asphalt concrete overlays. It provides useful information to help readers understand the effects of different material and loading type parameters on the fracture properties of asphalt concretes. It also reviews relevant numerical and experimental studies, and describes in detail design parameters such as aggregate type, air void, loading mode, and additives, based on the authors experience and that of other researchers.

The purpose of this manual is to familiarize industry and students with the technology of asphalt in its several forms namely asphalt cement, cutback asphalt, and asphalt emulsions. The laboratory work is designed to develop an understanding of asphalt properties, characteristics, testing procedures, and specifications. The procedures outlined are all derived from ASTM designations and practice as recommended by the Asphalt Institute. Where the particular ASTM method permits alternate procedures, the one more applicable to the available equipment and the teaching situation was chosen. The manual consists of the following: ò 35 of the frequently used ASTM tests in Asphalt Binder and Mix Design. ò Sample computations and easy to use data sheets, most of which have been developed specifically for the manual. ò An up-to-date overview of Asphalt Technology including sources, historical development, and classifications of asphalt products. ò Easy to understand explanations for Voids Mineral Aggregate, Absorbed Asphalt, Effective Asphalt Content, Percent Air Voids, and Percent of Voids filled with Asphalt. ò A stand-alone asphalt manual, written specifically for university laboratory instruction, yet applicable for a commercial testing laboratory. Rarely will other reference materials need to be referred to. ò Dimensions in both the SI and the US Standard systems of measurement. ò An appendix with conversion factors, rules of safety and procedures, overview of SHRP SUPERPAVE, explanation of asphalt emulsions, and additional data sheets on single-sided pages.

This is the first volume of a two-volume set of critical reviews of many aspects of both asphaltenes and asphalts and their interrelationship. Asphaltene is invariably present in asphalt or bitumen and other fossil fuel-derived liquids such as coal tar, coal liquefaction products, pyrolyzed shale oil from oil shales, source rock extracts and numerous naturally occurring bituminous substances. The latter include asphaltites, asphaltoids, waxes, and carbonaceous deposits containing a composition of petroleum and coal. The contents cover not only the basic science of asphaltene but also deal with the applications and technology such as upstreams (production, recovery) and down streams (refining, upgrading) of petroleum, and the paving technology and formulation preparation. The main features of the book are: it provides an up-to-date, in-depth review of every aspect of asphaltenes and asphalts; it spans five decades of research and technology of heavy fractions of petroleum; it presents a global view of asphaltene related to exploration production, refining and upgrading. The book will be welcomed as a valuable reference source for petroleum companies, research institutes, refineries, universities and also by individuals dealing with the production, origin, formation, engineering, conversion and catalysis of heavy oil, tar sands and other bitumens materials.
