Tentative Scope

The past few years have seen some very significant advances in concrete technology. Newer types of concrete admixtures and cementitious materials have emerged allowing the development of new types of concretes. Self-consolidating concrete, high strength concrete, and ultra-high strength concrete have found widespread use in bridge girders and other transportation related structural components. Rapid setting concretes are increasingly being used for accelerated construction and repairs. Pervious concrete has also found uses in transportation applications for stormwater management. Roller compacted concrete, formerly used in large part for military and industrial and port facilities, is becoming a larger part of state transportation agency work. Increased emphasis on the sustainability of concrete construction has led to increased interest in the use of recycled concrete as an aggregate. The importance of temperature control for mass concrete has also been realized.

The concrete technology is also facing some emerging challenges that need to be addressed. These include the depletion of high quality, durable aggregates in many parts of the country, changes to power generation that reduce the supply and consistency of acceptable fly ashes, and the incorporation of other traditionally land-filled materials into cement and concrete. In addition, barriers exist to the incorporation of new concrete technologies into transportation projects.

While information about these new concrete technologies is widely available in published literature, there is no single document available to help and guide transportation professionals in selecting appropriate new concrete materials and technologies as well as appropriate tests and QA/QC guidance to properly use these new technologies. Information will be collected by literature review and survey of transportation agencies.

The product of this study will be a synthesis report that provides an overview of current available concrete technologies and how they can be used in various transportation applications. Information will be collected by literature review and survey of transportation agencies. Specific technical methods, data sources, procedural guidance, and case studies will be collected to provide assistance to transportation agencies on integrating emerging concrete technologies. Way to incorporate materials, techniques, and methods and procedures into specifications will also be addressed. Gaps in concrete technology for particular applications will be identified as well as research needed for a more economical, effective, and sustainable use of concrete in transportation.
