"Poor joint performance in whitetopping overlays increases the magnitude of the interlayer debonding stress and load related stress, which can result in corner and longitudinal cracks. However, currently available whitetopping design procedures do not account for the joint performance. Fiber reinforced concrete (FRC) is commonly used in constructing these overlays but the contribution of the fiber to load transfer has never been quantified either.\r\nUnder the scope of this dissertation, a new, economical, small-scale joint performance characterization procedure (BALT) was developed. The results from the BALT procedure were validated by comparing them to the results from large scale joint performance tests (SALT). The joint performances of one plain concrete (PC) and two FRC mixtures were characterized with respect to mixture type, crack width and number of load cycles. Load transfer efficiency (LTE) and dissipated energy ratio (DER) prediction models were developed for all the mixtures. It was found that FRC provides a 15 to 25 percent higher joint performance as compared to PC. The fiber plays a larger role in load transfer when the joint is fatigued. Interestingly fibers do not fatigue even after 10 million load cycles. Using finite element analysis, a relationship was developed for determining the joint stiffness (AGG*) for whitetopping overlay. It was found that the load-related stress can be reduced by 6 percent with application of FRC while the interface debonding stress can be reduced by 50 to 72 percent.\r\n"^^ .
