WEBINAR: “Petrographic Laboratory Investigations of the Oldest Concrete Pavement in America—Bellefontaine, OH”

Presented by Gerard Moulzolf, American Engineering Testing (AET)
Presenting a case study of the oldest concrete pavement in America (in Bellefontaine, OH).

Summary: In the summer of 2016, AET was contacted by the American Concrete Paving Association (ACPA) to investigate concrete from Court Avenue in Bellefontaine, Ohio—the oldest concrete pavement in the United States. The study involved several collaborating parties in both the private and academic sectors to assess the physical, chemical, and geologic properties of the historic pavement, which is still in service. The goals of the investigation were to understand how a concrete pavement placed in 1893 is still performing and what implications can be drawn to modern portland cement concrete pavements (PCCP’s) used in highway construction.
