Title: DIFFERENCE OF RESULTS BETWEEN DYNAMIC AND STATIC ANALYSES OF FWD DATA
Abstract: Results of structural evaluation analysis of pavement using FWD data from route 219 at Saito in Miyazaki Prefecture, Japan are presented. FWD is a dynamic loading device. DSGT, a dynamic analysis method and AASHTO and NIPPO which are static analysis methods, are used for the analysis. Subgrade modulus and effective pavament full depth AC thickness are backcalculated. A potential problem of whether static analysis (mostly used method) or dynamic analysis should be performed on the data is discussed in this paper by looking at the difference of results these two methods give in the analysis of FWD data.
