NRMCA Vice President of Pavement Structures Brian Killingsworth recently presented Roller Compacted Concrete: Introduction to Design at the Pennsylvania Aggregate and Concrete Association’s RCC Workshop and Demonstration held in Williamsport, PA. The presentation focused on the key design parameters needed for RCC pavement structural design as well as the design tools available to pavement engineers to conduct the designs.

Questions and discussion throughout the presentation focused on the freeze-thaw durability of RCC as well as the considerations for leaving RCC unsurfaced or surfacing with a thin asphalt concrete layer. Participants included commercial and industrial property owners, design professionals and public officials including members from PennDOT. Other presentations discussed the cost advantages of RCC versus other pavement types and typical RCC applications. Several local case studies were also highlighted. After the morning presentations, attendees were taken to Centre Concrete’s Montoursville, PA, plant to view a demonstration of RCC placement.
