What causes a pavement to crack? - ACPA

The friction or bond restrains the 's volume change (shrinkage or contraction), inducing higher stresses than might occur in 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).
