Abstract

A performance engineered mix (PEM) design was utilized on I-29 in Harrison county in Iowa. In 2019, the standard quality management concrete (QMC) mix was used. In 2020, the PEM mix was used with a reduced cement content. Comparing testing between the two mixes revealed similar to better results with the PEM mix design, including better smoothness.
