The literature presents the research results of athree-dimensional analysis of a concrete barrier andanchor slab on a reinforced soil (MSE) retaining wallsystem under AASHTO impact test loading. It has thepotential to assist practicing engineers andresearchers in understanding the characterization ofa concrete barrier, anchor slab, and reinforced soilretaining wall assembly under an impact load condition. This literature investigates the stresses on theconcrete barrier with anchor slab, as well as stressdistribution on the concrete barrier that is underimpact loads specified by the AASHTO code. Adiscussion of the pattern of the potential yield zoneon concrete barrier is included in this literature.Few research models are established to compare theyield zones and stress distributions. Based onresearch results, this literature questions the yieldline theory defined by AASHTO. It could potentiallyallow practicing engineers to understand the designconcept of the yield line defined by AASHTO andproduce new topics for future research.
