ABSTRACT
Norwegian road specifications propose a linear temperature correction factor for revising the bearing capacity formula at different temperatures. The current study intends to reevaluate this correction factor. For this purpose, deflection measurements obtained from Falling Weight Deflectometer were analyzed. Six roads in the Norwegian road network were considered and the measurements were repeated for three different temperatures. For each section of the roads, master curves for deflections at zero (D 0) and 20 cm (D 20) distances from the center of the load were developed. Then, a reference temperature (20℃) was considered and the corrected values of D 0 and D 20 were obtained for this temperature accordingly. Comparing bearing capacity obtained from corrected deflections with uncorrected bearing capacity led to the development of a new temperature correction factor. It was shown that the new developed factor resembles the current factor proposed by the specifications.
