WebPavement blowups are not the only distress caused by environmental conditions: shoulder rotation, thermal cracking, rutting, shoving, and corrugation are all affected by temperature; corrugation, frost heave, deflection, cracking, and reduced load-bearing capacity are all affected by subsurface moisture; and pumping is affected by precipitation. WebHowever, as the age of concrete pavements placed largely during the Interstate construction era (1950s through 1980s) continues to increase it is worthwhile to consider how the next generation of concrete pavements will be evaluated, designed, constructed, maintained and (ultimately) disposed.
