Abstract:

The portland cement concrete (PCC) pavements at two Wisconsin airports, Central Wisconsin Airport in Mosinee, and Outagamie County Airport in Appleton, were monitored during spring thaw in 1986. To evaluate pavement performance during this period, falling weight deflections were taken. In addition, surface and subsurface temperatures were measured at selected sites at the two airports. Since the current Federal Aviation Administration PCC pavement design criterion is based on limiting the bending stresses in the concrete slab under edge loading conditions, the major portion of the evaluation was on load transfer during the spring thaw period. This paper presents the results of the field study at these two airports.
