dc.description.abstractConventional bridge design has been challenged by durability and reliability issues due to expansion joints. Chloride-contaminated infiltration and debris accumulation in traditional expansion joints affect the bridge performance negatively. Link slab has emerging as an effective alternative in bridge rehabilitation and design by eliminating expansion joints while the bridge structure remains simply supported. Engineered Cementitious Composites (ECC) and Ultra-High Performance Concrete (UHPC) are desired material in link slab application due to their high strength and tensile ductility. Presented in this thesis is a research project conducted by the BEST center at the University of Maryland to study link slab application with UHPC and ECC. Two bridge models were generated for finite element analysis. In addition, a field test was prepared. Experiments were carried out to study material properties of ECC and UHPC for a preliminary assessment of link slab performance using these materials. Results found that ECC and UHPC are adequate for link slab for their strength, high tensile ductility and fine cracks development.en_US
