TEMPERATURE ADJUSTMENT FACTORS FOR FALLING WEIGHT DEFLECTOMETER DEFLECTIONS ON FULL DEPTH ASPHALT CONCRETE PAVEMENTS

A convenient way to gauge the structural capacity of a pavement is to compute the structural number (SN). To make the structural capacity of various pavements comparable to each other, the SN, and therefore the Falling Weight Deflectometer (FWD) measured deflections that the SN is based on, must be corrected to a common temperature (68 deg F). In this report, a temperature adjustment factor curve (Temperature Adjustment Factor vs. Average Asphalt Concrete Mix Temperature) was developed in order to correct FWD deflections to 68 deg F. Also included in this report is the comparison of different methods used to determine the elastic modulus of the pavement, the elastic modulus of the asphalt concrete, and the subgrade resilient modulus.
