FHWA’s Advanced Concrete Pavement Technology Program Virginia Concrete Conference Richmond, VA March 4, 2011 Sam Tyson Federal Highway Administration Office of Pavement Technology Concrete Pavement Technology Program Long-Life Pavement • FHWA Conference on Long-Life Concrete Pavements – October 2006. • What is a Long-Life Pavement? • Original service 40+ years; • No premature construction defects or material-related distress; • Reduced potential for cracking, faulting & spalling; • Smoothness and surface texture easily maintained. Concrete Pavement Technology Program Benefits Derived from Long-Life Pavements • Maintenance of Traffic • Work Zone Safety Reduced User Delays Life-Cycle Cost Sustainability • • • • • • Economic Impacts Environmental Impacts Social Impacts Concrete Pavement Technology Program Long-Life Pavement • Options with Concrete – • • • • • • • Jointed Plain (Reinforced); Continuously Reinforced; Precast Jointed; Precast Prestressed; Bonded Overlays; Unbonded Overlays; Roller Compacted. Concrete Pavement Technology Program Concrete Pavement Technology Program Continuously Reinforced Concrete Pavement (CRCP) Cooperative Effort with Concrete Reinforcing Steel Institute (CRSI) • Manual for Design and Construction published in 2009; • Workshop Series started January 2010; • LA, AR, AZ, OR & CA completed; GA scheduled March 23, 2011. Concrete Pavement Technology Program Precast Concrete Pavements Prestressed & Doweled Systems Concrete Pavement Technology Program Precast Concrete Pavements • Maintenance of Traffic – Night- time and Off-Peak Work Zones; • Long-Life Pavement Performance. VDOT – Prestressed Project on I-66 – 2009 Concrete Pavement Technology Program Roller Compacted Concrete (RCC) Cooperative Effort with the National Concrete Pavement Technology Center (CP Tech Center) • Manual for Design and Construction published in 2010; • Delivery to be scheduled. Concrete Pavement Technology Program Advanced Concrete Pavement Technology Best Practices for Concrete Pavements • Development and Publication of Tech Briefs and Guidance Documents; • Demonstration and Loan of Testing Equipment for Concrete and Pavements; • Delivery of Workshops and Conferences on Selected Topics.
