Concrete Pavement Technology Update
FHWA Cooperative Agreements to Advance Concrete Pavement Technologies
The Federal Highway Administration (FHWA) recently entered into three cooperative agreements with outside agencies to advance concrete pavement design and construction technologies in support of the Concrete Pavement Technology Program (CPTP). Each agreement provides an initial year of funding with up to four additional years at FHWA’s discretion and available funding.
Technology Transfer of Best Practices for Concrete and Concrete Pavements (American Concrete Institute). This agreement will provide education and training activities for FHWA’s customers and partners. Deliverables include—
Advancement of Continuously Reinforced Concrete Pavement (CRCP) Through Technology Transfer and Delivery of Industry Guidance for Design and Engineering (Concrete Reinforcing Steel Institute). Products of the ongoing FHWA CPTP include technical guides addressing the design, construction, and repair and rehabilitation of CRCP that are available for review and implementation by highway agencies. FHWA found that new efforts are needed to create, across the entire pavement community, a national awareness of and a willingness to accept CRCP as a proven pavement technology. The agreement provides for an advisory Expert Task Group (ETG) of pavement community representatives. Deliverables include—
Advancement of the Precast-Prestressed Concrete Pavement (PPCP) System Through Technology Transfer and Development of Industry Guidance for Design and Engineering (Precast-Prestressed Concrete Institute). This agreement will encourage timely acceptance and technically sound implementation of PPCP as a proven alternative pavement system. A strategic, national communications plan will be structured to gain the support of decision makers across all elements of the pavement community. Deliverables include—

National Conference on Preservation, Repair, and Rehabilitation of Concrete Pavements
April 22–24, 2009 —— St. Louis, Missouri
In today’s environment, where highway agency budgets cannot fully meet pavement management needs, it is important that the limited funds available be expended in an optimum manner—to extend the useful life of pavements at the least life-cycle cost.
Over the past two decades, there has been much progress in developing effective preservation, repair, and rehabilitation (PRR) techniques. However, many gaps remain, and many practices are not implemented consistently from one region to another. This conference will gather information from around the country to close those gaps.
The conference program will present best practices in the use and timing of various PRR treatments to extend the structural capacity and functional characteristics of concrete pavements. In peer-reviewed papers and invited presentations, the program will address evaluation of concrete pavement condition and new advances in PRR technology. Case studies from highway agencies and industry will be highlighted.
The conference will explore closely related topics such as sustainability, accelerated construction, alternative contracting methods, remaining service life and economic tradeoffs, forensic investigations, mitigation of materials-related distresses, and the latest equipment, materials, and testing methods.
Details on paper submission, program, and venue are posted at http://www.fhwa.dot.gov/pavement/concrete/2009cptpconf.cfm and updated periodically.
