The Shell Bitumen Handbook has been regarded for many years as the authoritative source of information on bitumens used in road pavements. This new edition seeks to enhance that reputation. For over a hundred years Shell has been at the forefront of bitumen technology and continues to lead in research and development. The Shell Bitumen Handbook reflects this leading role. Compiled by authors from Shell offices around the world, The Shell Bitumen Handbook provides global best practice for civil engineers in pavement construction and maintenance to apply to projects of their own, as well as comprehensive theory for students and researchers. New to this edition, chapters covering: warm asphalt mixtures; sulphur extended asphalt; sustainable road pavements. Even in our internet age, there are some essential hard copy references that have a place on the diminishing bookshelves of most practising engineers and materials scientists. The distinctively yellow-bound Shell Bitumen Handbook, first published in 1949 and now issued in its sixth edition, is certainly one such valued book. It replaces the fifth edition of 2003 and is completely reorganised, thoroughly updated and expanded by around 50%. Three principal authors, led by civil engineer and expert asphalt consultant, Dr Robert Hunter, are supported by a panel of specialist authors, many of whom are with Shell Bitumen. Those familiar with the fifth edition will find the chapters rearranged somewhat, with a net increase in chapters from 20 to 24 and a doubling of appendices from 4 to 8. The new chapter sequence approximately follows the life of bitumen, from its origins and manufacture, through its properties and use in asphalts, then design, installation and performance of asphalt pavements, to durability and other applications for bitumen and asphalt. Two of the new appendices indicate an objective to make the handbook more international: Appendices 5 and 6, respectively, list bitumen and asphalt product standards across the world. In the former, different principles are used in various regions, with performance graded (PG) specification being used in North America and partly in China, whereas empirical testing is used elsewhere, such as penetration/softening in Europe, Africa and much of Asia, and viscosity in Australasia, the Indian subcontinent, Mexico and parts of South America (and for soft grades in Europe); unfortunately, there is some minor inconsistency between the text and the map in Appendix 5. A surprising omission from the previous edition was guidance on the design of asphalt mixtures. This gap is well and thoroughly addressed in the new edition, with a completely new, 50-page Chapter 12. In common with all the chapters in this book, Chapter 12 is clearly written and beautifully presented, being both easy and a pleasure to read, supported by full-colour diagrams of impressive clarity; there are no photographs in this particular chapter, but elsewhere there are plenty of good-quality images, as appropriate. This new chapter provides a grounding in the principles that underpin asphalt mix design, notably mixture volumetrics and aggregate grading , then explains the four most widely implemented design methods, all of which were developed in the USA: Hubbard Field , Hveem (or California ), Marshall (or Corps of Engineers , perhaps the best known) and Superpave (the most recent, resulting from a research programme initiated in response to increasing premature pavement failures). As well as reorganisation and the new chapter on asphalt mix design, existing users will be pleased to know that this new edition sets out to update the whole opus, and two splendid examples are the completely new Chapter 7 on rheology of bitumens and the extended Chapter 8 (formerly Chapter 5) on polymer-modified bitumens and other modified binders. The former is a most valuable 30-page addition on a critical property, especially with the growth in the use of polymer-modified bitumens, authored jointly by specialists from Shell (Dr Richard Taylor) and the University of Nottingham (Professor Gordon Airey). A potentially complex account of the science of rheology is handled with skill and clarity, then the rheological behaviour of bitumen is considered first in terms of a low-temperature linear elastic region , then a high-temperature viscous region and finally an intermediate temperature visco-elastic region.

Modifiers have been used to improve the performance of asphalt/aggregate mixtures for building roads for over the past hundred years and during that time the industry has evolved into a sophisticated sector that is heavily regulated by national and European standards.

The modifiers used take many different forms: polymers, latex, and many chemical additives. Determining how modifiers actually affect the performance of a mixture and establishing construction quality control procedures for these modifiers can be extremely difficult. In the past these difficulties have caused many specifying agencies to avoid the use of mixture modifiers when they could be of benefit to the performance of the road.

This review explores the type of polymers used in asphalt, why they are used, where they are used in terms of applications and the benefits they offer to industry and the road user. In particular, the reader will understand how polymers can be used to enhance the functionality of asphalt, that is to overcome deterioration mechanisms by enhancing asphalt stiffness or flexibility, or by making it more resistant to deformation (rutting) caused by traffic.

This review of polymers in asphalt is supported by an indexed section containing several hundred key references and abstracts selected from the Polymer Library. It is aimed at anyone who has an interest in polymers and their highway applications.

The investigative assault upon the enigmatic asphaltenes has recently resulted in sig­ nificant advances in many varied disciplines. Taken individually, each discipline exposes certain facets of asphaltenes, but each, alone, can never reveal asphaltenes from all van­ tages. Even seemingly narrowly focused issues such as the molecular structures of asphal­ tenes, or the colloidal structures of asphaltenes require a confluence of many lines of investigation to yield an understanding which differs from truth by diminishing uncer­ tainty. An holistic treatment of the asphaltenes is a powerful approach to evolve further their understanding. For example, examination of asphaltenes at the highest resolution yields molecular structure. A slight increase in scale probes asphaltene colloidal structure. Weaving together asphaltene studies performed at different length scales results in a fabric which envelops an encompassing vision of asphaltenes. At the same time, the interfaces of these hierarchical studies provide additional constraints on imagination, more than investi­ gations at individual length scales alone. These considerations shaped the timing, format, and the content of our book. The editors are very appreciative of the diligence and hard work manifest in each of the contributed chapters herein. We thank the contributing authors for making this project a success

Maximize the Quality and Longevity of any Highway Work: Ten peer-reviewed papers give you a timely look at HMA smoothness measurements, specifications, and equipment. Evidence shows that pavements constructed with low roughness measurements perform longer with fewer needed maintenance activities than pavements with a higher level of initial roughness. This collection of papers, written by industry experts, provides and overview of the current approaches to constructing smooth HMA pavements.
Three sections cover: State Agency Perspectives - provides insight into both the history of the development and the implementation of ride quality specifications for new hot mix asphalt pavements in Alabama, Arizona, New Jersey, Virginia, and Tennessee. These papers highlight the wide range of differences in equipment and approaches used to quantify HMA smoothness by state agencies across the country. This information will provide the readers with insight into complexities associated with developing and implementing ride quality specifications. National and International Perspectives - uses analysis of the Long Term Pavement Performance (LTPP) national pavement database to determine the effect of various construction alternatives on the smoothness of the final HMA surface. It also presents correlation equations that relate the traditional, but slow, method of measuring roughness with a hand-operated profilograph to that measured with the state-of-the-art vehicle-mounted. A second paper compares the use of six devices for measuring roughness on recently constructed Taiwan highways. This information will prove especially useful for agencies faced with assessing ride quality in confined urban areas. Equipment Comparisons, Materials Considerations, and Analyses - focuses on how various HMA mixtures, friction courses, and construction practices influence smoothness measurements and pavement quality; and compares the results obtained from an inclinometer profiler and a vehicle mounted profiler when used to test a wide range of HMA mixtures. Correlations between construction practices and their influence on roughness are also presented. It also discusses a new method for analyzing the raw profile obtained by a wide range of profilers. This analysis method can be used to improve data processing for any equipment that collects the raw profile.

In the years since the development and subsequent success of Stone Matrix Asphalt (SMA), a plethora of articles have emerged, scattered throughout various publications. The time is right for a comprehensive resource that collects, examines, and organizes this information and makes it easily accessible. A compilation and distillation of the latest knowledge available, Stone Matrix Asphalt: Theory and Practice describes SMA, from its origin through implementation, and explores various methods and design approaches.

Detailing the requirements and materials for the mix, including asphalt binder, aggregates, and stabilizers, the book covers standard and alternative design methods and their execution, as well as best practices and production processes. It addresses issues such as permanent deformation and fatigue resistance, as well as special applications, such as bridge deck surfacing and airfields. The book uses practical examples to illustrate theory, presents practical tips useful in everyday work, and includes a review of problems that can occur during laydown, and their potential solutions.

Drawn from the author’s extensive experience during the introduction of SMA in the early 1990s and discussions with many process engineers, the book provides the practical information needed to customize methods for individual applications of SMA. Blazejowski puts together a picture, drawn from a broad range of literature. The result: a reference that is handy, practical, and easy to use.
