The January 2020 issue of Roads & Bridges focuses on the concrete world. Our top story looks at a concrete pavement replacement and intersection improvement project in the city of Avon Park, Florida where S.R. 64 meets U.S. 27. We also look at the rehabilitation efforts on two historic bridges in Philadelphia—including the country's oldest continuously used roadway bridge and one of the longest and highest concrete arch spans in the world. You can also read a piece from ACPA’s Bill Davenport on how a performance-engineered mixture program can create longer-life concrete pavements. Finally, this issue looks at the work conducted by researchers at the University of Minnesota at Duluth on finding the correct structural fiber for thin concrete pavements.
