• 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.
