Abstract:The main objective of this Guide is to provide a source of information to structural designers for the design and construction of highway bridges and related structures using high performance concrete (HPC). This Guide will be updated periodically to keep pace with the latest developments in HPC. The Guide addresses all basic aspects of developing and producing HPC with desirable and beneficial characteristics for the transportation community. Section 1 discusses the objective and scope of the Guide. Section 2 introduces the topic of HPC implementation in the United States highway infrastructure and provides historical context of this development. Section 3 addresses the characteristics and grades of HPC for various applications and environment. Section 4 is devoted to recently-completed national research and ongoing testing into the next generation of HPC, along with web links to State Department of Transportation research reports. Section 5 highlights material properties of HPC that are important to owners and designers in assuring long-term structural performance. Section 6 provides guidelines for developing HPC mix designs and proportioning of materials. Section 7 focuses on the fabrication, transportation and erection of precast, prestressed HPC beams. Section 8 applies to HPC cast-in-place construction in substructures and superstructures, with special attention to the construction of bridge decks. Section 9 identifies the most common instruments that can be used for field measurement and recording of strain, deflection, rotation, acceleration and temperature of HPC members. Section 10 provides cost information and methods for assessing the cost effectiveness of HPC with guidelines for estimating initial construction cost and life-cycle cost. Finally, Section 11 provides an overview of several HPC projects across the United States with lessons learned and contact information or web links for further details.
