What causes a concrete pavement to crack? – ACPA

The friction or bond restrains the concrete’s volume change (shrinkage or contraction), inducing higher stresses than might occur in concrete pavement on granular subbases. According to Okamoto, as the subbase friction increases, cracks occur from smaller drops in surface temperature than are necessary on low-friction subbases (2).
