Abstract:This study presents the fi rst approach to develop a new concrete pavement structure reinforced only with fi bers. This
research will identify probable combinations of fi bers (dosage and length combinations) that will adequately perform
in repeated load fatigue tests. While fi bers and high dosage fi ber combinations have
been previously used in concrete, these combinations have never before been used in a
Department of Transportation (DOT) pavement structure. The major diff erence between
previous applications and the current objective is number and level of load applications. The
fundamental objective of this research is to determine how CFRCPs behave under highwaytype
loading.
The specific objectives of the study include:
1. Characterize the fresh and hardened properties of CFRCP concrete.
2. Determine the comparative fatigue resistance of diff erent fi bers, and diff ering fi ber
blends and dosage rates.
3. Provide recommendations for future research, including full scale loading and possible
fi eld implementation sites.
