Superpave Mix Designs for Low-volume Roads by Edward J. Engle Pdf
The purpose of this research was to determine if the Superpave mix design strategy for low volume roads was practical and economical. Eight projects were selected in five counties. The projects were completed in the summer of 1998. Performance evaluation of the resulting pavements was carried out annually.
Evaluation of the Superpave Gyratory Compactor for Low Volume Roads by Stephen Alan Cross,Johnson Choho Lee Pdf
There is evidence that some Kansas mixes, which have performed well in the past, will not meet the currently proposed design requirements for a Superpave level I mix. The major problem is low voids in the mineral aggregate (VMA). The major reasons for low VMA are the high amounts of natural sand currently used and the higher compactive effort required by Superpave compared to 50-blow Marshall compaction. Cores, plant produced (field) mix, the original aggregates and asphalt cement were obtained from four low volume pavements. The cores established the in-place density of the pavements. The field mix was compacted in the Superpave Gyratory Compactor (SGC) to establish the number of gyrations required to reach the field density of the mix. The aggregates and asphalt cement were obtained and Superpave mix designs were performed. The void properties were evaluated at the original and revised Ndesign gyrations. The effect of reducing the ram pressure from 600 kPa to 400 kPa was evaluated as well.
The Superpave Mix Design Manual for New Construction and Overlays by Ronald J. Cominsky Pdf
This laboratory manual presents Superpave mix design system in a complete, step-by-step format. It is intended for engineers and technicians in public and private organizations to use when designing paving mixes for all classes of highways, from farm-to-market roads to urban freeways. An essential companion to this manual is "The Superpave Mix Design System Manual of Specifications, Test Methods and Practices." The Superpave software program--"The Superpave Specification, Mix Design and Support Program"--And its users manual are also necessary to take full advantage of the mix design system.
Low-Volume Road Engineering by Robert A. Douglas Pdf
"Everything that sustains us – grown, mined, or drilled – begins its journey to us on a low-volume road (Long)." Defined as roads with traffic volumes of no more than 400 vehicles per day, they have enormous impacts on economies, communication, and social interaction. Low-volume roads comprise, at one end of the spectrum, farm-to-market roads, roads in developing countries, northern roads, roads on aboriginal lands and parklands; and at the other end of the spectrum, heavy haul roads for mining, oil and gas, oil sands extraction, and forestry. Low-Volume Road Engineering: Design, Construction, and Maintenance gives an international perspective to the engineering design of low-volume roads and their construction and maintenance. It is a single reference drawing from the dispersed literature. It lays out the basic principles of each topic, from road location and geometric design, pavement design, slope stability and erosion control, through construction to maintenance, then refers the reader to more comprehensive treatment elsewhere. Wherever possible, comparisons are made between the standard specifications and practices existing in the US, Canada, the UK, South Africa, Australia and New Zealand. Topics covered include the following: Road classification, location, and geometric design Pavement concepts, materials, and thickness design Drainage, erosion and sediment control, and watercrossings Slope stability Geosynthetics Road construction, maintenance, and maintenance management Low-Volume Road Engineering: Design, Construction, and Maintenance is a valuable reference for engineers, planners, designers and project managers in consulting firms, contracting firms and NGOs. It also is an essential reference in support of university courses on transportation engineering and planning, and on mining, oil and gas, and forestry infrastructure.
BITUMINOUS ROAD CONSTRUCTION IN INDIA, SECOND EDITION by KANDHAL, PRITHVI SINGH,VEERARAGAVAN, AMIRTHALINGAM,CHOUDHARY, RAJAN Pdf
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

Volumetric Requirements for Superpave Mix Design by Donald W. Christensen,Ramon Francis Bonaquist,National Cooperative Highway Research Program Pdf
TRB's National Cooperative Highway Research Program (NCHRP) Report 567: Volumetric Requirements for Superpave Mix Design examines whether changes to the recommended Superpave mix design criteria for voids in mineral aggregate, voids filled with asphalt, and air voids content might further enhance the performance and durability of hot-mix asphalt.
The SUPERPAVE Mix Design System Manual of Specifications, Test Methods, and Practices by Edward T. Harrigan,Rita B. Leahy,Jack S. Youtcheff Pdf
The final product of the Strategic Highway Research Program (SHRP) Asphalt Research Program is the SUPERPAVE (registered trademark) mix design system for new construction and overlays. This system employs a series of new performance-based specifications, test methods, and practices for material selection, accelerated performance testing, and mix design. This report documents these new specifications and procedures in a format suitable for eventual American Association of State Highway and Transportation Officials (AASHTO) standardization.
