SPR-4717: Assessment of Temperature Correction Factors for Falling Weight Deflectometer Deflections

This study will develop an enhanced method of temperature correction on the FWD deflections to minimize temperature effects during FWD data analysis. The field investigation and numerical analysis will be conducted to identify the relationship between FWD deflections and testing temperatures. Based on the identified relationship, the FWD temperature correction guidelines will be established.
