Abstract:
The Federal Highway Administration (FHWA) under its Testing and Evaluation program (TE-30) on High-Performance Concrete (HPC) pavements had initiated several field demonstration projects to evaluate the use of new technology to improve the long-term performance of the pavements. Under this program, the Minnesota Department of Transportation (Mn/DOT) has successfully completed the construction of the first 60-year design life HPC pavement in the state along Interstate I-35W. Significant changes to materials-related specifications that affect the long-term performance of the concrete pavement were implemented in this project. This paper will provide a brief description of the Mn/DOT’s first HPC pavement project along with key design features of the pavement, including use of slag cement in high-performance concrete mixtures, higher level of entrained air content than that is conventionally used, and stainless steel dowel bars. Also, the results of quality control tests conducted on field concrete during construction are presented.
