Products to Improve Concrete Pavement Performance

PDF Version (3.1 mb)
The Concrete Pavement Technology Program (CPTP) is a national program of research, development, and technology transfer that operates within the Federal Highway Administration (FHWA) Office of Pavement Technology.
The CPTP includes some 30 research and demonstration projects, each of which is delivering products for improved design, construction, repair, and rehabilitation of concrete pavements (see table below). The focus of the program is on cost-effective designs and procedures for long-life performance of Federal-aid highways.
FHWA established goals for the CPTP, reflecting critical needs, as follows:
- Reduce user delays.
- Reduce costs.
- Improve performance.
- Foster innovation.
These goals address the needs of the State departments of transportation (DOTs), the concrete pavement industry, and the highway user, while supporting FHWA's strategic goals to improve the mobility, productivity, and safety of the Nation's highway system. The CPTP supports these goals with products that result in longer lasting, better performing pavements with safer and smoother rides.
Improved pavement performance, in turn, minimizes traffic congestion by reducing the need for work zones for repair and rehabilitation.
Technology transfer of products resulting from the CPTP is being accomplished under CPTP Task 65. This 5-year activity was initiated in September 2003 and is overseen by an Executive Expert Task Group (ETG) that includes State DOT chief engineers and representatives from industry and academia.
An Engineering ETG, made up of pavement and materials engineers from State DOTs, FHWA field offices, plus representatives from industry and academia, reviews the technical aspects of CPTP products. These products include:
- Guidelines / Technical briefs
- Test protocols / Draft specifications
- Software
- Workshops / Conferences
- Presentations / Videos
- Field demonstrations
- Equipment loans (available from FHWA's Mobile Concrete Laboratory)
