Analysis of the structural condition of pavement using deflection data of Falling Weight Deflectometer (FWD) is to evaluate the strength of pavement structure using Non-destructive test. The aim of this study is to evaluate the structural performance of flexible pavement using ELMOD 5 program compared to the AASHTO 1993 method in Jagorawi toll road, section Bogor-Ciawi. <br /> <br /> <br /> Using AASHTO 1993 method which modeling two-layer system of pavement based on cumulative design ESAL for 2007 to 2012 are 15.709.392 ESALs/lane of direction A and 13.484.406 ESALs/lane for direction B, the average overlay thickness is higher than the results of ELMOD program which modeling threelayer and four-layer structure of pavement. <br /> <br /> <br /> The differences between Elasticity Modulus and material characteristics of each pavement layer are caused by the differences of methodology, data input, pavement structure model, temperature correction, and back calculation method. <br /> <br /> <br /> The number of pavement layer will determine the accuracy of result calculation, as shown by the comparison of ELMOD program (three and four-layer) to the AASHTO 1993 method (two-layer). Whereas, the higher the cumulative, the <br /> <br /> <br /> higher the overlay thickness.
