<p align="justify">To maintain level of service of Highway we need an appropriate evaluation method both functional and structural evaluation. At this time, evaluation method in Indonesia can not be used to assess whether the overlay will occur fatigue cracking. Austroads 2011 Method is one method which is used as reference in Indonesia where this method has been accommodating resistance to fatigue cracking criteria. There for we need a study of Austroads 2011 method with the goal whether this method can be applied in Indonesia. <br /> <br /> <br /> <br /> The structural evaluation was perform based on Deflection data from the FWD (Falling Weight Deflectograph) measurement using the Austroad 2011 Method version General Mechanistic Procedure with the output is allowable repetition loading for both fatigue cracking criteria and permanent deformation criteria. In <br /> <br /> the structural analysis was made 5 types of modeling, in order to determine what type of material that gives the most influence on the overlay and how the influence of the number of layers to the overlay. While the functional evaluation was perform based on roughness data from NAASRA with the output is IRI (International Roughness Index) value which one it can be determined whether the pavement is in good condition or not. <br /> <br /> <br /> <br /> The results of this study showed that the old asphalt material provide the greatest influence whereas the granular material gives enough influence and then the <br /> <br /> number of layer in a modeling less influence to the overlay thickness. From traffic analysis indicate that the value DSAR7 by Austroads 2011 Method was identical <br /> <br /> with the value CESAL by Bina Marga Method. For functional analysis, 63,5% of segment 1 is in good condition and 36,5% in poor condition, while the second <br /> <br /> segment of 84.4% in good condition and 15.6% in poor condition. The application of Austroads 2011 Method for the pavement condition in Indonesia need to consider several things like: the modeling of pavement structure, type of vehicle, the presumptive value in the Austroads 2011 Method, the value of material properties, the deflection measurement and the value of IRI.<p align="justify">
