Interlocking concrete pavements are flexible pavements. Flexible means that loads are distributed through the base by point-to-point contact and interlock between the aggregate.

Interlocking pavers spread loads across the base. They can move with minor movements in the base without cracking. This gives them a distinct advantage over asphalt and poured concrete. These pavements can crack more readily should the base move from loads or settlement. They also crack from expansion and contraction due to changes in weather.

As an added benefit, flexible pavements can move slightly from normal movement in the soil from seasonal changes in the moisture without losing their load-spreading ability.
