The NCC E-News is issued by the National Concrete Pavement Technology Center. The following are covered in more details with links to research reports.
• The July 2018 MAP Brief, “Using RCA in Pavement Base Products,” provides a summary of constructability considerations, qualification testing and pavement design considerations for both unbound and bound (stabilized) RCA base applications.
• Dr. Tyler Ley at Oklahoma State University has developed a video series on the Tarantula Curve for optimizing grading of aggregates in concrete mixtures.
• The Missouri Department of Transportation polled the NCC group regarding the use of base type and thickness for portland cement concrete (PCC) pavements and hot-mix asphalt (HMA) pavements.
• A project from Purdue University’s Joint Transportation Research Program attempted to quantify the effects of fly ashes on the properties of pastes.
• A study by the Missouri University of Science and Technology aimed to develop an effective methodology for using saturated lightweight sand (LWS) for internal curing.
• The Central Iowa Expo facility in Boone, Iowa, was reconstructed in 2012 to provide an improved pavement foundation for portland cement concrete (PCC) and pavement with hot-mix asphalt (HMA).
• A study from the Louisiana Transportation Research Center evaluated the MIT-SCAN-T2 as a non-destructive pavement thickness measuring device for quality control and quality assurance.
• A project from the Missouri University of Science and Technology - Rolla studied the design and performance of cost-effective ultra-high performance concrete (UHPC) for bonded bridge deck overlays.
