Recently, link slab was proposed to replace the conventional dowelled-joints in jointed plain concrete pavements (JPCP) after it was previously employed in bridge expansion joints to avoid the problems associated with dowel bar joints. This study introduces numerical modeling of the proposed link slab expansion joints that simulates the joint behavior and provides the basis for optimal joint design using Abaqus software. The generated model and its boundary conditions are based on recent experiments conducted on the proposed joint. The model consists of two conventional concrete blocks which represent two slabs of JPCP and ultra-high performance concrete (UHPC) link slab that is connected to JPCP using double headed shear studs. The materials involved in the model are concrete damage plasticity to model conventional concrete and UHPC, and elastic-plastic material to model Grade 40 steel shear studs that connects the UHPC link slab to the conventional concrete slabs. The numerical model simulated the experiments very well. The numerical results were comparable to the experimental results in terms of load-relative deflection and deflection profile of the unloaded slab. Also, the failure mode was captured very well in the numerical model.
