National Concrete Consortium (NCC) E-News November 2016
In association with the CP Road Map Program
The National Concrete Consortium (NCC) E-News is the newsletter of the Long-Term Plan for Concrete Pavement Research and Technology (CP Road Map)—a national research plan developed and jointly implemented by the concrete pavement stakeholder community.
Moving Advancements into Practice (MAP) Briefs describe promising research and technologies that can be used now to enhance concrete paving practices. The November 2016 MAP Brief, “Causes of Transverse Cracking in Concrete Bridge Decks”, lays out the current understanding of what elements tend to increase or reduce bridge deck cracking.

NCC State Surveys: Member states of the NCC have the ability to poll other member states regarding specifications, materials, construction, research, or other issues related to concrete paving. This section highlights some of the questions posed and answers received through the NCC’s ListServ feature.
Field Tester Training and Certification and Implementation of the Super Air Meter: The Minnesota Department of Transportation (MNDOT) polled the NCC group with two questions on concrete field tester certification. The first item asked agencies how they currently certify concrete field testers. Twenty-five agencies responded. The majority … continue reading.
State Agency Research and Technology Transfer Needs: Attendees at the August 2016 NCC conference were asked for input on their top research and technology transfer needs. Thirty-one state DOTs responded. This feedback will help guide the future direction of the CP Tech Center. The following is a summary of the top priorities: … continue reading.
NEWS FROM THE ROAD highlights research around the country that is helping the concrete pavement community meet the research objectives outlined in the CP Road Map:
Field Testing of Internal Curing: Both Louisiana and Iowa recently constructed bridges utilizing internally cured concrete (ICC). Recent research has indicated several benefits to using lightweight fine aggregate (LWFA) in mixtures for bridge decks. Internal curing supplies curing water from … continue reading.
Cost-Effective Base Type and Thickness for Long-Life Concrete Pavements: The quality of a portland cement concrete (PCC) pavement foundation is vital for the successful construction and long-term performance of the pavement. This study reviewed the performance of in-service pavements at the MnROAD facility. Data were obtained from … continue reading.
Concrete Debris Assessment for Road Construction Activities: The Florida Department of Transportation investigated two distinct issues related to the effect of concrete on the environment: Concrete Grinding Residue (CGR) and Recycled Concrete Aggregate (RCA). To investigate these concerns, laboratory tests were performed on eight RCA samples from various recycling facilities across Florida … continue reading.
