The aim of the studies presented in this report is the implementation of rational concepts and testing procedures for the design and manufacture of bituminous materials for applications in pavement construction. Practical test procedures are recommended for binder evaluation, mix design and performance assessment of bituminous materials. The three main topics addressed are binder testing, mix design and mechanical testing of mixtures. Each is examined through interlaboratory tests and there is a literary review of existing practices and methods for the production of polymer modified binders, mixture design and the mechanical properties of mixtures.

Highway engineers are facing the challenge not only to design and construct sustainable and safe pavements properly and economically. This implies a thorough understanding of materials behaviour, their appropriate use in the continuously changing environment, and implementation of constantly improved technologies and methodologies. Bituminous Mixtures and Pavements VII contains more than 100 contributions that were presented at the 7th International Conference ‘Bituminous Mixtures and Pavements’ (7ICONFBMP, Thessaloniki, Greece 12-14 June 2019). The papers cover a wide range of topics: - Bituminous binders - Aggregates, unbound layers and subgrade - Bituminous mixtures (Hot, Warm and Cold) - Pavements (Design, Construction, Maintenance, Sustainability, Energy and environment consideration) - Pavement management - Pavement recycling - Geosynthetics - Pavement assessment, surface characteristics and safety - Posters Bituminous Mixtures and Pavements VII reflects recent advances in highway materials technology and pavement engineering, and will be of interest to academics and professionals interested or involved in these areas.

Bituminous Mixtures and Pavements contains 113 accepted papers from the 6th International ConferenceBituminous Mixtures and Pavements (6th ICONFBMP, Thessaloniki, Greece, 10-12 June 2015).

The design and construction of “long and deep” tunnels, i.e. tunnels under mountains, characterised by either considerable length and/or overburden, represent a considerable challenge. The scope of this book is not to instruct how to design and construct such tunnels but to share a method to identify the potential hazards related to the process of designing and constructing long and deep tunnels, to produce a relevant comprehensive analysis and listing, to quantify the probability and consequences, and to design proper mitigation measures and countermeasures. The design, developed using probabilistic methods, is verified during execution by means of the so called Plan for Advance of the Tunnel (PAT) method, which allows adapting the design and control parameters of the future stretches of the tunnel to the results of the stretches already finished, using the monitoring data base. Numerous criteria are given to identify the key parameters, necessary for the PAT procedure. Best practices of excavation management with the help of real time monitoring and control are also provided. Furthermore cost and time evaluation systems are analysed. Finally, contractual aspects related to construction by contract are investigated, for best development and application of models more appropriate for tunnelling-construction contracts. The work will be of interest to practising engineers, designers, consultants and students in mining, underground, tunnelling, transportation and construction engineering, as well as to foundation and geological engineers, urban planners/developers and architects.

This is the first ever text-cum-reference book in India on “Bituminous Road Construction”. It includes references to the codes and specifications of the Indian Roads Congress and the Bureau of Indian Standards (BIS), besides the international standards such as ASTM and AASHTO. This book provides a thorough knowledge of bituminous road construction such as bitumen; aggregate; mix design; special mixes such as stone matrix asphalt and warm mix asphalt; structural design of flexible pavements; asphalt production and construction; distresses in asphalt pavements; maintenance and rehabilitation of asphalt pavements including recycling; and interesting investigations of premature failure of asphalt pavements across the world. It includes a large number of photographs for easy comprehension of the subject matter. This book has been designed to serve as a text for the undergraduate and postgraduate students of Civil Engineering for the courses on: Highway Materials including Testing Laboratory; Asphalt Mix Design; Highway Construction and Maintenance; Highway Pavement Failures; and Design of Flexible Pavements. Cutting-edge technology on bituminous road constructions, included in the book, helps M.Tech and Ph.D. students in conducting research in this field. Since over 95% of highways have bituminous surface, this book is also an ideal reference for thousands of practicing highway engineers who are engaged in the most ambitious highway construction programme ever in India. Highlights of the Second Edition: • Incorporates cutting-edge technology on the topics covered • Includes new sections on bitumen chemistry; durability of bitumen; Balanced Mix Design (BMD); asphalt mix characterization; perpetual pavements; QC/QA in India; and rehabilitation of distressed concrete pavements with bituminous overlays; and life cycle costs of bituminous versus concrete pavements. TARGET AUDIENCE • B.Tech Civil Engineering • M.Tech Highway Education • Practicing Highway Engineer

In recent years, with the rapid development of the world transportation industry, the proportion of asphalt pavement in road engineering is increasing. Therefore, while the demand for asphalt and asphalt mixture is increasing, the quality requirements for materials are also improving. In particular, new materials and new technologies are constantly emerging, and the application technology, theory, and technical specifications of asphalt materials have made great progress.

The micro- and nano-modification of infrastructure materials and the associated multi-scale characterization and simulation has the potential to open up whole new uses and classes of materials, with wide-ranging implications for society. The use of multi-scale characterization and simulation brings the ability to target changes at the very small scale that predictably effect the bulk behavior of the material and thus allowing for the optimization of material behavior and performance. The International RILEM Symposium on Multi-Scale Modeling and Characterization of Infrastructure Materials (Stockholm, June 10-12, 2013) brought together key researchers from around the world to present their findings and ongoing research in this field in a focused environment with extended discussion times. From asphalt to concrete, from chemistry to mechanics, from nano- to macro-scale: the collection of topics covered by the Symposium represents the width and depth of the currently ongoing efforts of developing more sustainable infrastructure materials. Researchers, practitioners, undergraduates and graduate students engaged in infrastructure materials or multi-scale characterization and modeling efforts can use this book as a comprehensive reference, to learn about the currently ongoing research efforts in this field or as an inspiration for new research ideas to enhance the long-term performance of infrastructure materials from a fundamental perspective. The Symposium was held under the auspices of the RILEM Technical Committee on Nanotechnology-Based Bituminous Materials 231-NBM and the Transport Research Board (TRB) Technical Committee on Characteristics of Asphalt Materials AFK20.

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.
