Latest Edition of National Concrete Consortium Newsletter Now Available Online
The NCC E-News is issued by the National Concrete Pavement Technology Center. The following are covered in more detail with links to research and other reports:
• The December 2018 MAP Brief, “Performance Experience and Lessons Learned from SPS 2 Test Sections of the Long-Term Pavement Performance Program (LTTP),” provides a summary of the performance and lessons learned from the SPS-2 test sections and includes highlights from the SPS-2 Tech Days.
• Recent publications from the CP Tech Center: 1. Guide for Concrete Pavement Distress Assessments and Solutions and 2, Three-webinar series on microfibers in concrete pavements
• Member states of the National Concrete Consortium (NCC) have the ability to poll other member states regarding specifications, materials, construction, research or other issues related to concrete paving.
• NCHRP Research Report 858 presents a framework for quantifying the effects of preservation treatments on pavement performance, along with a guidance document to facilitate implementation of the framework.
• A study was conducted in South Dakota to develop optimized concrete mixtures for jointed plain concrete (JPC) pavements and evaluate newly constructed JPC pavement sections in the field.
• A report from the Texas A&M Transportation Institute provides recommendations for the implementation of steel fiber-reinforced concrete (SFRC) in Arizona.
• A study from the Louisiana Transportation Research Center reviewed the practices and requirements for early-opening-to-traffic concrete used by state DOTs.
• NCHRP Synthesis Report 530 identifies practices for constructing or rehabilitating concrete pavements under traffic using projects representing a wider range of conditions and techniques than had previously been studied.
• A project from the University of Alaska, Fairbanks, sheds light on the role of class C coal fly ash (CFA) in the cement hydration process and outlines the potential benefits of the expanded use of various CFAs in cementitious materials.
