UNCERTAINTIES IN DESIGN OF CONCRETE PAVEMENTS DUE TO DIFFERENTIAL SETTLEMENTS AND VOLUMETRIC CHANGES

A STUDY OF CONCRETE RUNWAYS IS MADE ON THE SENSITIVITY OF COMPUTED AND MEASURED STRAINS, DEFLECTIONS, AND SUBGRADE REACTIONS TO UNCERTAINTIES IN VARIABLES OF WEATHER, DIFFERENTIAL SETTLEMENTS, AND PROPERTIES OF MATERIALS. STRAINS CAUSED BY VOLUMETRIC CHANGES OF THE PAVEMENT AND SUBGRADE MATERIAL AND THOSE CAUSED BY WHEEL LOADS ARE CONSIDERED. DESIGN REQUIREMENTS OF RUNWAY AND SUBGRADE FOR PURPOSES OF WEATHER MAY BE OPPOSITE TO THOSE FOR PURPOSES OF LOAD. GEOMETRY OF THE DEFLECTED PAVEMENT IS THE DOMINATING CHARACTERISTIC OF DEFORMATIONS PRODUCED BY VOLUMETRIC CHANGES OF SUBGRADE OR OF THE PAVEMENT MATERIAL.
