The overlay design analysis in the 1993 AASHTO Guide for Design of Pavement Structures introduces nondestructive deflections testing as a primary means of evaluating the in situ structural capacity of existing pavements. In order to use the approaches recommended in the ASHTO Guide, deflection measurements or backcalculated layer properties must be corrected to a particular type of loading system and a standard set of environmental conditions. One of the major environmental factors affecting surface deflection measurements of flexible pavements is the pavement temperature. During the course of the study, FWD tests and temperature measurements have been conducted on seven pavement sections at different regions of North Carolina. The field data obtained from four pavements in the central region during the 92/93 study are also included in the analysis. The new temperature correction procedure is composed of the algorithm predicting the AC layer mid-depth temperature as affective AC layer temperature and the temperature correction procedure for deflections and backcalculated moduli.
