The risk of cracking in a concrete pavement that is opened to traffic at early ages is related to the maximum tensile stress that develops in the pavement and its relationship to the measured, age dependent, flexural strength of a beam. The stress that develops in the pavement is due to several factors including traffic loading and restrained volume change caused by thermal or hygral variations. The stress that develops is also dependent on the time-dependent mechanical properties, pavement thickness, and subgrade stiffness. There is a strong incentive to open many pavements to traffic as early as possible to allow construction traffic or traffic from the traveling public to use the pavement.
