Q. Avoidance of designing acute angle of concrete pavement

The stress persuaded in acute angle corners of concrete pavement is far much higher than right-angle corners of the pavement. For example concrete pavement corner of acute angle of 70^opersuades stresses about 50% more than stress persuaded by an angle of 90^o. Accordingly corners of concrete pavement shouldn't be designed with acute angles to avoid corner cracking. If it is essential to adopt acute angles for concrete pavement, special reinforcement has to be provided to strengthen these corners.
