A new brochure on high-performance concrete (HPC), High-Performance Concrete Bridges: Building Bridges for the 21st Century (Publication No. FHWA-SA-98-084), is now available from the Federal Highway Administration (FHWA). The brochure provides, in a handy question and answer format, an introduction to HPC and its many uses and benefits, as well as a list of resources for States that want to learn more about HPC. To obtain a copy, contact the FHWA Research and Technology Report Center at 301-577-0906 (fax: 301-577-1421).
The Lead States team for HPC, originally created to promote HPC bridges, recently broadened its mission to include the use of HPC mixes in concrete pavements. To support this effort, the team has expanded to include Washington State Department of Transportation (DOT), Iowa DOT, and Arizona DOT, as well as representatives from the American Concrete Pavement Association and FHWA.
Looking for a list of contacts who can provide information and advice on using the Superpave mix design system? Consult FHWA's updated Directory of Superpave Resources (Publication No. SA-97-083). The new directory can be ordered from the FHWA Research and Technology Report Center at 301-577-0818 (fax: 301-577-1421). The directory can also be found on the Web at www.ota.fhwa.dot.gov/pubs/index.html.
Several new members have joined the American Association of State Highway and Transportation Officials' Task Force on SHRP Implementation. Doug Rose of Maryland DOT has replaced Ken Shiatte, from New York State DOT. Dave Ekern of Minnesota DOT has taken over for Gene Ofstead, recently retired from Minnesota DOT. Meanwhile, Gary Carver of Wyoming DOT has filled the position previously held by John Conrad, the committee's new chairman, who hails from Washington State. Conrad's predecessor as chairman, Bobbie Templeton, has retired from Texas DOT and is now serving as the administrator of the National Quality Initiative.
Dick McComb of FHWA's Office of Technology Applications has retired after 32 years of service to FHWA. Over the course of his career, McComb served as division chief of the Office of Research and Development, was one of the first loaned staffers to the Strategic Highway Research Program, and managed the Applied Research and Technology Program.
A new Tech Brief, WIM Scale Calibration: A Vital Activity for LTPP Sites, is available from FHWA. The brief discusses the importance of direct calibration of weigh-in-motion (WIM) scales at long-term pavement performance (LTTP) test sites. In all, 14 Tech Briefs, which summarize reports from the LTPP program, have been issued. Copies of the briefs can be found on the Web at www.advancenet.net/~fhwa/documents/tech.html.
