Cracks that Occur Well After Sawing— Sometimes cracks continue to form as much as 60 days to 2 years after paving and sawing are complete. In some cases these may be cracks that formed early but were not visible. In other cases, uncontrolled cracking that first occurs or continues to develop well after paving and sawing is a clue that something is restraining or moving the concrete slabs to ...

Sometimes, the pavement does not crack completely below the saw cut, and thus, any liquid accumulated in the joint will tend to saturate the surrounding concrete, thus accelerating its freeze–thaw deterioration.

There is a discontinuity in concrete at saw cut joints and wheel loads are not transferred 100 % from one slab to the next, resulting in higher wheel load stress. When incompressible materials get into the joints, expansion of concrete slabs due to high ambient temperatures will squeeze the incompressible materials and high localized stresses ...

Joints are placed in Portland cement concrete pavements (PCCP) to control random cracking. These joints provide a weakened plane that enables a crack to form in a controlled manner, relieving residual stresses that develop when thermal, hygral, or hydration movements are resisted by sub grade and adjoining pavement. While the concept of creating a weakened plane through saw-cutting is ...
