The stress induced in acute angle corners of concrete pavement is far much higher than that in right-angle corners of the pavement. For instance, concrete pavement corner of acute angle of 70o induces stresses about 50% more than the stress induced by an angle of 90o. As a result, corners of concrete pavement should not be designed with acute angles to avoid corner cracking. If it is necessary to adopt acute angles for concrete pavement, special reinforcement has to be provided to strengthen these corners.
