Outline

• HPC Introduction
• 2006 National HPC Survey
  • Alternative Reinforcement
  • Self-Consolidating Concrete
  • Lightweight HPC
• Conclusion

PURPOSE

• Quantify the number and application of high performance concrete (HPC) projects across the nation,
• Obtain information on the use of high performance reinforcement.
• Follow-up to earlier HPC Survey 2003

QUESTIONNAIRE

• Prepared by a task force of the FHWA High Performance Concrete Technology Delivery Team
• Members of task force include
  • State DOT
  • Industry
  • FHWA

SURVEY DISTRIBUTION

• Survey sent to:
  • 50 States
  • Federal Lands Highway
  • Puerto Rico
  • District of Colombia (DC)

SURVEY TOPICS

• General Use of HPC
• HPC for Permeability Benefit
• HPC for Strength Benefit
• Self-Consolidating Concrete
• Lightweight HPC
• Alternative Reinforcement

SURVEY TOPICS (cont.)

• Alternative Reinforcement
  • Stainless Steel Reinforcement
  • Stainless Steel Clad Reinforcement
  • Epoxy Coated Reinforcement
  • Galvanized Reinforcement
  • MMFX Microcomposite (MMFX-2) Reinforcement
  • FRP Reinforcement
    • GFRP
    • CFRP
    • AFRP

SURVEY TOPICS (cont.)

• General Section
  • Primary characteristics of HPC tested
  • Method for specifying HPC
  • Number of projects planned and constructed
  • HPC Specification
  • Percentage of HPC used in the last 3 years (check)

Conclusions

• HPC Provides
  • Extension of service life
  • Reduced Maintenance
  • Lower Life Cycle Cost
• Significant progress in HPC Implementation in the past 15 years, however, more needs to be done
• State DOT and Industry have taken advantage of strength and durability oh HPC

Conclusions (cont.)

• Researchers and academics have provided solutions to design and construction problems
• FHWA has supported the research, development, deployment and implementation of HPC through the many programs and intiatives described above
• FHWA will continue to ensure that public and private sector partnerships be strenghthened for succesful implementation of HPC
