Hairline longitudinal crack in the crown or invert indicate that the reinforcing steel has accepted part of the load. Cracks less than 0.01 inches in width are minor and only need to be noted. Cracks greater than hairline cracks, or those more than 0.01 inch in width but less than 0.1 inches (slightly more than the thickness of a nickel), should be noted as possible candidates for maintenance. Longitudinal cracking in excess of 0.1 inch in width may indicate overloading or poor bedding.
