State Of The Art Compaction Of Asphalt Pavements

This report is a collection of information from published research and from informal reports of methods and procedures. It was prepared by the HRB Committee on Flexible Pavement Construction. a subcommittee was formed to organize a conference---held during HRBs 48th annual meeting---on compaction. The material in the report is confined to hot- mix asphalt pavements.

Sulfur-Extended-Asphalt (SEA) binders save asphalt, a potential energy source, by replacing some asphalt in conventional flexible pavement mixes with sulfur. These new binders appear to possess properties comparable to asphalt. The guideline manual provides the highway community in both public and private organizations with the most definitive state-of-the-art guidelines extant for using these binders. Information on design, construction, quality control, equipment, mixing plants, specifications, and safety is included.

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

Pavement Engineering will cover the entire range of pavement construction, from soil preparation to structural design and life-cycle costing and analysis. It will link the concepts of mix and structural design, while also placing emphasis on pavement evaluation and rehabilitation techniques. State-of-the-art content will introduce the latest concepts and techniques, including ground-penetrating radar and seismic testing. This new edition will be fully updated, and add a new chapter on systems approaches to pavement engineering, with an emphasis on sustainability, as well as all new downloadable models and simulations.
