In the years since the development and subsequent success of Stone Matrix Asphalt (SMA), a plethora of articles have emerged, scattered throughout various publications. The time is right for a comprehensive resource that collects, examines, and organizes this information and makes it easily accessible. A compilation and distillation of the latest k
Prepared by the Emerging Materials Committee of the Materials Division of ASCE. This report presents a review of the state of the art on emerging materials for use in civil engineering infrastructure. Emerging materials include novel and new materials, as well as traditional materials with profound potential in new applications. A material or class of materials is considered "emerging" if its use has not yet progressed to a stage wherein well-established guidelines, codes, and specifications exist for its use. This report is conveniently divided into chapters that address specific classes of materials andØhighlight the most recent developments in materials technologies relevant to civil infrastructure.Ø Topics include: smart materials for civil engineering applications; fiber reinforced composites in civil infrastructure; emerging geomaterials for ground improvement; aluminum materials and the infrastructure; polymer concrete made with recycled plastics; state of the practice in asphalt technology; emerging uses for masonry materials; and emerging uses for window glass. The practicing engineer, student, or general reader will find this to be an easy-to-use reference for construction material systems that are being developed for use in civil engineering.
This synthesis report will be of interest to state, local, and federal agency pavement materials, design, and construction engineers, as well as pavement research engineers and scientists. Those with supervisory oversight for pavement programs will also find it of interest. It describes the current practice for methods to achieve rut-resistant durable pavements. The synthesis documents current experience with permanent deformation of asphalt pavements and identifies methods to improve performance. Information for the synthesis was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search using domestic and international sources. This report of the Transportation Research Board describes the extent of the rutting problem on the National Highway System, pavement mixture design issues, and the design of rut-resistant mixtures. In addition, alternate mixture types, including stone matrix asphalt and porous asphalt, are discussed, as well as international approaches to mixture design. Finally, the construction of rut-resistant mixtures, including the role of quality control and quality assurance methods, are discussed. A summary of permanent deformation causes and solutions is included in the appendix.
Asphalt Pavements provides the know-how behind the design, production and maintenance of asphalt pavements and parking lots. Incorporating the latest technology, this book is the first to focus primarily on the design, production and maintenance of low-volume roads and parking areas.Special attention is given to determining the traffic capacity, re
This report documents the construction and performance of the Colorado Department of Transportation's (CDOT's) first two Stone Mastic Asphalt (SMA) projects. The first project, located on SH 119 from SH 52 to Longmont, contained three SMA mixes, two polymer-stabilized mixes and one fiber mix. This project successfully demonstrated the design, production and placement of SMA. The second project located on the Colfax Viaduct in Denver was CDOT's first attempt to use SMA on a bridge deck. This project used a polymer-stabilized mix. This project successfully demonstrated the placement of SMA on a bridge deck. SMA is currently being used as a wearing surface in Colorado. Guidelines and a best practice guide have been developed and have been adopted for statewide use. In addition, CDOT's Bridge Branch has developed a specification for using SMA as part of the overlay system.
