The South Dakota Ready Mixed Concrete Association hosted its annual concrete workshop in Sioux Falls last week. The workshop was co-sponsored by the South Dakota chapter of the American Concrete Pavement Association. In the morning session, more than 75 attendees were presented with information on tilt-up wall buildings, concrete floors and the ACI 318 update coming in 2014. In the afternoon, NRMCA Vice President, Pavement Structures, Brian Killingsworth presented on concrete pavement design and then walked the audience through the ACPA StreetPave12 design program by providing hands-on software instruction and training.

Participants received instruction on designing a new concrete pavement, developing an equivalent hot mix asphalt pavement and conducting a life-cycle cost analysis. Killingsworth also shared the benefits of concrete overlays and performed a design in the StreetPave software. The audience was comprised of consultant designers, ready mix producers and public works personnel. Throughout the discussion, Killingsworth also reviewed the latest market dynamics and other factors that are making concrete pavements an increasingly wise choice for municipal and county pavements.
