Web Resource Chronicles CP Road Map Impacts
- Wednesday, 13 May 2020 13:42
The CP Road Map (or Long-Term Plan for Concrete Pavement Research and Technology) concluded in 2019, but its impact on concrete pavement research and technology transfer has been substantial, according to the CP Tech Center in its April-May “Resources” newsletter.
The Center has developed a website that captures the history of the CP Road Map, which was formally introduced in 2001 as a collaborative effort among the FHWA, ACPA (and its Innovative Pavement Research Foundation), CP Tech Center (formerly the Iowa State University’s Center for Portland Cement Concrete Pavement Technology). Over time, the initiative expanded in recognition that no single organization was large enough or well-resourced enough to pursue research & technology (R&T) needs alone. Federal, state and local agencies, industry and academia collaborated and contributed funding to what the large scale initiative.
The CP Tech Center has created a well-organized and comprehensive web-based resource center that captures the background, history, accomplishments, and research tracks that became the CP Road Map. A section called “So what now?” describes ongoing activities aimed at contributing further to concrete pavement R&T. Click here to explore the information, photos and other resources.

The latest issue of the National Concrete Consortium (NCC) News* provides an update on the CP Road Map plan jointly developed and implemented by concrete pavement stakeholders, including ACPA and the CP Tech Center. Here are summaries of three reports that caught our eye:
Investigation of the Iowa DOT bridge deck epoxy injection process – This report summarizes how the injection of epoxy resin into the cracks and voids on concrete overlays has been used across Iowa. The technique has had positive results in preserving concrete overlays, which have been used on bridge decks in Iowa since the 1970s.
Environmental Impacts and Design on Performance – This report details a study of the effects of environmental factors and pavement design on pavement performance in the absence of heavy loads. Results showed an average of 36% and 24% of total damage was related to environmental factors for flexible and rigid pavements, respectively, at 15 years.
A Cost-Effective Ultra-High Performance Concrete (UHPC) – This report presents the development of UHPC using locally available materials in Colorado. Locally sourced materials are said to reduce construction costs when compared to commercially produced products. The report examines implications of various constituent types with an emphasis on silica compounds, steel and polypropylene fibers.

The latest news about the long-term plan for the Concrete Pavement Research and Technology, also called the CP Road Map, includes some excellent updates. Here are two that caught our attention:
- The publication of a research report called, “Reliable Early Opening Strength for Concrete Pavements and Patch Work,” which presents results of study by the Louisiana Transportation Research Center. The research evaluated jointed plain concrete pavement performance in relation to dowel bar alignment using the new MIT-SCAN2-BT technology.
- The CP Tech Center has published a comprehensive report called “Technology Transfer of Concrete Pavement Technologies,” which summarizes the accomplishments asssociated with the cooperative agreement between the center and the FHWA over the past five years. The goal of this project was to help bring the latest concrete pavement innovations, knowledge, and technologies to state transportation agencies in support of the Accelerated Implementation and Deployment of Pavement Technologies (AID-PT)* program goals. The cooperative agreement was a direct result of ACPA’s ongoing advocacy efforts, which not only led to the vision and direction of AID-PT, as well as benefits to the concrete pavement community.
These and other reports may be found in the current issue of CP Road Map E-News, produced by Dale Harrington and Sabrina Shields-Cook.
* AID-PT was the result of a legislative provision championed by ACPA and included in both the Moving Ahead for Progress in the 21st Century Act (MAP 21) and more recently, the Fixing America’s Surface Transportation Act (FAST Act), signed into law in December 2015. AID-PT created both a mechanism and funding for the delivery of pavement technology for both the concrete- and asphalt-pavement industries. Since its inception, the program has resulted in benefits to the concrete pavement community, including other contracts and cooperative agreements with CP Tech Center, an ACPA Technology Partner.
