INDICATIONS ABOUT THERMAL GRADIENT MAGNITUDES FROM FIELD STUDIES OF CONCRETE BOX GIRDER BRIDGES

Three years of continuous thermal data from three concrete box girder bridges and one concrete box girder pier are compiled into a single study. The data are used to draw conclusions about trends in thermal gradient magnitudes and shapes. The maximum gradients from the data are compared to AASHTO recommended design gradients. Statistically appropriate design gradient magnitudes are then selected from the data. Conclusions concerning the effects on thermal gradient magnitudes from cross-section shape, asphalt topping, and motor traffic are presented.
