16. Abstract
To demonstrate the suitability of using high performance concrete (HPC) in highway structures, the FHWA
initiated a series of projects in 1993 that included plete incorporation of HPC — from design to long-term
monitoring of the bridges in service. The report focuses on the design and construction of the first two of these
projects in the United States, namely, the Louetta Road Overpass in Houston, Texas (Research Study 9-580), and
the North Concho River Overpass in San Angelo, Texas (Research Study 9-589).
This report summarizes the observations of, and conclusions obtained from, both laboratory and field
investigations related to these two HPC bridges. It investigates HPC properties, mix design, applicability of
current design requirements, applicability of current construction practices, predictability of short- and long-term
performance, and the requirements for quality control and quality assurance testing and inspection. The
performance-related test re
