Peak Temperature Determination of Drilled Shafts Excluded from Mass Concrete Consideration in Current Specifications

The first objective of this research project is to obtain field temperature data from drilled shafts suspected to exceed present temperature limits to evaluate the current practices and propose modifications to the Standard Specification to increase durability and structural longevity of drilled shafts. The second objective is to develop a Florida Method that specifies the materials and procedures required to instrument and record the temperature profiles of the core and surface of a drilled shaft as it cures. Included within this method or in a separate Florida Method, detail the equipment and procedures to estimate drilled shaft core temperature from thermal integrity testing.
