Implementation Support for Strategic Highway Research Program II (SHRP2) Renewal Project ROSE Real-time Smoothness Measurements on Portland Cement Concrete Pavements During Construction

The overall objective of the Strategic Highway Research Program (SHRP2) project R06E Real-Time Smoothness Measurements on Portland Cement Concrete (PCC) Pavements during Construction was to enable real-time control of concrete pavement smoothness during construction by evaluating and demonstrating promising technologies, and the development of both model specifications and construction guidance that are capable of working with the identified technology in such a way as to further the objective of rapid implementation by State Highway Agencies. Seven potential real-time smoothness measurement devices were identified and studied as part of the project. Two of the devices were found to warrant subsequent evaluation and demonstration as part of Phase Ill of the project: These included the GOMACO Smoothness Indicator (GSI) and the Ames Engineering Real-Time Profiler (RTP). The GOMACO device was piloted and evaluated during concrete paving projects in Arkansas and Michigan, and the Ames device was piloted in Texas, Michigan, and New York. During the project, it was noted that there was consensus among contractors that the real-time smoothness measuring technology represents a valuable process control tool in that the ability to have real-time feedback from intentional process changes has the greatest potential to make lasting improvements in the smoothness of concrete pavements. While the current state of the practice is to cautiously make an equipment/process change and wait approximately 24 hours for feedback when the hardened pavement can be profiled, real-time smoothness measuring devices allow the contractors to make adjustments to their concrete equipment and/or process while the concrete is still wet, minimizing more costly corrections later. Specific information about the SHRP 2 Program and a copy of the R06E Research Report may be found online at: The objectives of this Task Order are to provide technology deployment support as described below: (1) equipment loan program; (2) conduct showcases; (3) conduct workshops; (4) documentation of results/case studies; (5) specification refinement; and (6) marketing & outreach. These objectives seek to ensure routine use of the R06E product technology by Agencies and contractors that routinely construct PCC projects.
