Final Scope

The past few years have seen some significant advances in concrete technology. For example, newer concrete incorporating advances in admixtures and cementitious materials has emerged. 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, used in large part for military, industrial, and port facilities, is becoming a larger part of state transportation work. Ultra-high performance concrete and internal curing are subjects of increasing interest as well as the importance of temperature control for mass concrete.

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. Challenges may also include having to overcome barriers, such as institutional and cultural barriers of the agency, to the incorporation of new concrete technologies into transportation projects.

While information about these new concrete technologies is available in published literature, there is no single document available on existing applications and practices for state departments of transportation (DOTs). Beneficial to DOTs would be the awareness and sharing of information on the application of appropriate new concrete materials and technologies.

The objective of this study will be to provide 1) an overview of new concrete technologies suitable for transportation applications, 2) state DOT applications of new technologies, and 3) recommendations for future research to advance promising new technologies. Information will be collected by a review of domestic and international literature and survey of transportation agencies. Specific technical methods, key references, procedural guidance, and case studies will be collected to demonstrate the application of emerging concrete technologies and potential advantages and concerns. Research needed for implementation of new concrete technologies will be identified.
