Due to the size of the individual PaveDrain blocks, the joints are designed to be left open; aggregate interlock and re-filling is not required, which greatly reduces maintenance.
No steel is used in the pavement--experience has shown excellent aggregate interlock at joints making dowels unnecessary.
A unified model for RC interface stress transfer was presented based on a combination of a generic bar model and a physical model for aggregate interlock [18].

In porous asphalt, the source of stability is aggregate interlock enhanced by the coarse aggregate.
And, because of its size relative to the chip seal, an aggregate interlock occurs between the anti-skid and the surface aggregate, as considerably more anti-skid is left in the traffic lanes as an abrasive for future storms.
Due to the lower modulus of asphalt binder at high temperatures, the high-temperature shear strength of the asphalt mixture is notably contributed to by aggregate interlock, which is mostly influenced by the morphological characteristic of mineral aggregate.
The authors found that the reinforced foamed OPS concrete beams had about 10% higher shear strength compared to conventional reinforced NWC beams and attributed this to the good aggregate interlock of OPS aggregates.
They attributed this to the enhanced dowel action of the reinforced OPS concrete beams in addition to the good aggregate interlock. In this research, the BS and EC codes were found to give good comparison of the shear resistance of reinforced OPS concrete beams, particularly the beams without shear reinforcement.
The fracture characteristic of material is dependent on the fracture mechanisms such as initiation of crack, propagation of crack growth, aggregate interlocks, and arrest of crack.
