Unlike former studies, the shear resistance is explained in terms of three major components: 1) friction component, 2) shear through component and 3) dilation component. The friction component is commonly quantified using the material friction angle, while the shearing trough component is quantified using a cohesion intercept that represents the phenomenon of shearing off intact material. The last component is described as the dilation component which represents the tendency of opposing roughness features to override one another and can be quantified as a dilation angle. The contribution of each component is found to be dependent on six major factors; joint opening, aggregate size, age of concrete at time of cracking, the concrete strength at the joint/crack interface, aggregate quality and overall roughness at the crack interface. Four out of the aforementioned factors are discussed in this paper. These four factors include: Joint opening, aggregate size, aggregate quality and overall roughness.
