Performance Survey on Open-graded Friction Course Mixes


Book Description

This synthesis will be of interest to pavement construction, maintenance, design, and materials engineers; pavement contractors; and others interested in the use of open-graded friction course (OGFC) mixes. It describes the current state of the practice on the use of OGFC mixes, including information regarding design, materials, construction, maintenance, and rehabilitation strategies. Alternative treatments to traditional OGFC are also identified and discussed. Information was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search to gather additional insight into North American and European practices. This TRB report describes the recent performance of North American OGFC mixes and European porous asphalt by identifying benefits and stress indicators. A new generation of OGFC mixes has evolved over the last 5 years with changes that have been reported to dramatically improve performance. This synthesis describes new materials and design methods being used, as well as the applicability of the new generation of open-graded mixtures to North American use.




Asphalt Surfacings


Book Description

Asphalt Surfacings has been written as a reference to the various asphalt course materials and surfacing treatments that are currently available to engineers, enabling them to select the materials and/or treatment that are appropriate for use on specific sites. Appropriate reference is made to the lower structural layers as the properties of all layers interact in producing the required pavement. The current established position in the UK and the emerging developments throughout the UK and Europe are covered. The contributors are all acknowledged authorities on their particular topics selected from every part of the highway engineering industry to achieve a balance between the various approaches required by the different functions they perform.

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.




Asphalt Mixture Specification and Testing


Book Description

This guide reviews the way asphalt mixture can be specified, with particular emphasis on the test methods used to measure performance. The advantages and limitations of the tests are described for measuring the desired property, and engineers can specify a test according to the material’s use. The book starts with a resume of specifications and their relative advantages and disadvantages for different situations. Then different properties are discussed in terms of: their specification; the test methods that can be used (primarily the EN 12697 suite of European methods, of which the author has been responsible for drafting); the extent to which the results predict performance; the levels that can be achieved with different asphalt mixes and types; what levels, if any, should be specified in various situations and pavement layers; and which other properties are adversely affected by enhanced performance. The final section covers various aspects of sustainability, with a strong emphasis on durability. Better understanding should enable clients and consultants who specify pavements to produce durable asphalt pavements more economically, and also help asphalt producers and students trying to understand the black art of asphalt.




Asphalt Mixture Selection


Book Description

This practical guide starts with a survey of the types of site and the asphalt properties which are required. Various external influences which may affect the relative importance of some properties are addressed, and the interplay of sites and external is considered. Asphalt mixture types and their properties are reviewed, largely as defined in the EN 13108 series but subdivided into further categories, and into maximum nominal coarse aggregate sizes using EN 13043 basic set plus set 2 sizes. Guidance is given, including using flowcharts, of the different mixtures that are suitable for each situation. In some cases a range of choices or mixtures with different degrees of suitability is offered. The guidance covers surface course, binder course and base, but with more focus on the surface course where the external influence is most significant. The site and external influence combinations on which a mixture can be used successfully are also given. The book is primarily intended for those who select asphalt on an occasional basis, such as architects or housing developers, but could be of use to other engineers with limited experience. It is also useful as an educational textbook for those studying asphalt technology.

The Shell Bitumen Handbook


Book Description

"This new edition reflects many of the very significant advances which have taken place in the period since the last edition was published. I am confident that you will feel that this is a worthy addition to your asphalt book shelf." Robert Hunter This respected Handbook has earned its reputation as the authoritative source of information on bitumens used in road pavements and other surfacing applications. This new edition has been up-dated to ensure The Shell Bitumen Handbook retains its excellent reputation. This comprehensive Handbook covers every aspect of bitumen, from its manufacture, storage and handling to specifications and quality along with a whole chapter on bitumen emulsions. The mechanical testing and physical properties of bitumen, its structure and rheology, properties such as durability and adhesion, and the influence of these properties on performance in practice are all set out in individual chapters. A further chapter is devoted to the practice of enhancing the performance of bitumen's by the addition of modifiers. Considerable attention is given to the different aspects of asphalts, detailing types of mixture, their manufacture and testing, mechanical properties, transport, laying and compaction and mixture design. This excellent reference also devotes chapters to the important topics of analytical design of flexible pavements and the technology of surface dressing. Since the last edition, there have been significant strides in a number of key areas of asphalt technology. These include the development of new mixtures, an improved understanding of the mechanisms by which pavements fail and the availability of high-performance bitumens. The Handbook has been fully revised to reflect these advances, as well as updating the standard procedures and methods which are necessary nowadays for those involved in using asphalts in an environment of ever-more demanding specifications. Compiled by the Shell Bitumen European Technical Team The Shell Bitumen Handbook is intended to be of daily use to civil engineers in pavement construction and maintenance, and also to students and researchers.
