Interlocking Method What is interlock? it's the inability of a paver to move independently of its neighbors. It is critical to the structural performance of interlocking concrete pavement. When considering design and construction, three types of interlock must be achieved: vertical, rotational and horizontal interlock. Vertical interlock is achieved by the shear transfer of loads to surrounding units through sand in the joints. Rotational interlock is maintained by the pavers being of sufficient thickness, placed closed together, and restrained by a curb from lateral forces of vehicle tires. It's important to mention that Rotational interlock can be further enhanced if there is a slight crown to the pavement cross section. Besides facilitating drainage, the crown enables the units to tighten slightly, progressively stiffening through loads and minor settlement across the entire pavement, thereby increasing structural capacity. And when progressive stiffening has stabilized, the pavement experiences what is known as "lockup". Horizontal interlock is primarily achieved through the use of laying patterns that disperse forces from braking, turning, and accelerating vehicles. The most effective laying patterns for maintaining interlock are herringbone patterns. Testing has shown that these patterns offer greater structural capacity and resistance to lateral movement.
