The Winter 2023 newsletter of the National Concrete Consortium has the following items:
• Concrete Overlays: Background & Benefits - The Winter 2023 NC² Moving Advancements into Practice (MAP) Brief from the NC² Resource Library provides brief background information, technical resources, performance studies and key benefits for concrete overlays to argue that they should be considered a long-life preservation treatment for aging roadway facilities.
• Evaluation of Concrete Pavement Buckling in Wisconsin - The goal of this research evaluation from the Wisconsin DOT was to investigate buckling of concrete pavements; reveal the key factors that impact buckling and identify methods to reduce the risk of buckling.
• Use of Recycled Concrete Aggregate in Concrete Pavement Mixes - The main tasks of this research report from Middle Tennessee State University were to evaluate recycled concrete aggregates (RCAs) from various sources in Tennessee and to determine how RCAs influence the performance of Tennessee DOT paving concrete.
• Evaluation of Sustainable and Environmentally Friendly Stabilization of Cohesionless Sandy Soil for Transportation Infrastructure - This research from Texas A&M University studied the use of a geopolymer as a green alternate replacement for portland cement to stabilize cohesionless sandy soils in coastal areas.
• Optimal Approach for Addressing Reinforcement Corrosion for Concrete Bridge Decks in Illinois - This report from the Illinois Center for Transportation at the University of Illinois presents the results of a comprehensive literature review focusing on corrosion performance of reinforced concrete bridge decks, with a particular emphasis on the relative performance of alternative corrosion-resistant reinforcement types.
• Plant Bowen Will Showcase Largest Coal Ash Beneficial Use Project in the US - This article from Power magazine describes a plan by Georgia Power to start harvesting previously landfilled fly ash from its 3.4-GW Plant Bowen station in Bartow County for use in concrete mixes and construction projects.
• Evaluation of Penetrating Sealers for Concrete - This report from the CP Tech Center at Iowa State University analyzed three different water penetrating sealers for their ability to increase concrete pavement durability by reducing moisture and chloride ion penetration.
