Early Cracking of Concrete Pavement - causes and repairs

Concrete shrinkage starts as it cures. The temperature and moisture gradient that exists between top and bottom of the concrete pavement slabs causes the curling and warping of the slab. The natural response causes the concrete pavement to crack at regular intervals.

Concrete Pavement

As the concrete pavement hardens, it contracts and cracks. If the contraction joints have been correctly designed and constructed, the cracks will occur below the joints. As the concrete continues to contract, the joints will open-providing room for the concrete to expand in hot weather and in moist conditions.
