Download or read book Ultra thin Whitetopping UTW for General Aviation Airports in New Mexico written by Larry R. Lenke and published by . This book was released on 2002 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whitetopping is a pavement rehabilitation construction practice where portland cement concrete (PCC) is placed over an existing asphalt concrete pavement as an overlay. Ultra-thin whitetopping (UTW) is generally a thin overlay with a thickness between 2 and 4 inches. UTW is usually of high strength and made with fibers for improved tensile strength, ductility and enhanced fatigue life. UTW differs from conventional whitetopping because of the design and construction procedures that ensure substantial bonding between the UTW and the underlying asphalt. UTW also employs much closer joint spacing than conventional whitetopping; this reduces the load-induced stresses within the UTW. UTW does not make use of steel reinforcement. A literature and technology review found that UTW is a proven means of asphalt pavement rehabilitation for improved serviceability. The mechanistic design concepts for UTW are clearly established. The construction methodologies have been developed and are in place. The material technology for fiber reinforced high strength PCC is available. Specifications have been written and successfully used on numerous highwayand airport pavement projects. The initial cost of UTW is more than the common asphalt concrete pavement rehabilitation used in New Mexico. However, life cycle costs of UTW compared to asphalt overlays are considered competitive. It is recommended thatthe NMSHTD design and construct UTW test sections at an appropriate selected airport in the state of New Mexico. Such a project will allow for the determination of the relative initial costs of the UTW versus asphalt rehabilitation, and long term monitoring will allow for the determination of the life cycle costs and long-term performance of UTW versus asphalt.

Download or read book Concrete Pavement Design Construction and Performance written by Norbert Delatte and published by CRC Press. This book was released on 2007-09-12 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the interactions between the different design and construction variables and techniques this book illustrates best practices for constructing economical, long life concrete pavements. The book proceeds in much the same way as a pavement construction project. First, different alternatives for concrete pavement solutions are outlined. The desired performance and behaviour parameters are identified. Next, appropriate materials are outlined and the most suitable concrete proportions determined. The design can be completed, and then the necessary construction steps for translating the design into a durable facility are carried out. Although the focus reflects highways as the most common application, special features of airport, industrial, and light duty pavements are also addressed. Use is made of modeling and performance tools such as HIPERPAV and LTPP to illustrate behavior and performance, along with some case studies. As concrete pavements are more complex than they seem, and the costs of mistakes or of over-design can be high, this is a valuable book for engineers in both the public and private sectors.

Book excerpt: Bringing together in one volume the latest research and information, this book provides a detailed guide to the selection and use of aggregates in concrete. After an introduction defining the purpose and role of aggregates in concrete, the authors present an overview of aggregate sources and production techniques, followed by a detailed study of their physical, mechanical and chemical properties. This knowledge is then applied to the use of aggregates in both plastic and hardened concretes, and in the overall mix design. Special aggregates and their applications are discussed in detail, as are the current main specifications, standards and tests.

Download or read book Binders for Durable and Sustainable Concrete written by Pierre-Claude Aïtcin and published by CRC Press. This book was released on 2007-08-07 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Linking theory to practice, this book provides a better fundamental understanding of Portland cement and hydraulic binders which is necessary to make better concrete. It has been clearly demonstrated that concrete durability is closely linked to its water/binder ratio and proper curing during the first week after casting. In this rigorously presented work, Pierre-Claude Aïtcin explains the complexity of the hydration reaction and how to make, use and cure durable and sustainable concrete. This book also details the problems with Portland cement composition at present and outlines the concept of an ideal hydraulic binder which is technically and ecologically efficient, as well as being long-lasting and robust. Binders for Durable and Sustainable Concrete is a practical and innovative reference text which will be particularly relevant to engineers and chemists working in the Portland cement, concrete and admixture industries. This book will also be of interest to academics and graduate-level students in Civil Engineering departments who specialize in Portland cement and concrete technology.
