In Malaysia, the design flexible pavement issues in tropical soil became challenging to the geotechnical engineers especially at subgrade layer. This is because, the deflection of the subgrade were effected the de-bonded of flexible pavement from subgrade. Therefore, the purpose of this study is to determine the bonding state on flexible pavement subject to subgrade. This study focuses on determining deflection analysis technique for quality control characteristic applied onto tropical soil in Malaysia using a Falling Weight Deflectometer (FWD) Testing. The analysis of this method are presented and interpreted in the shape of the deflection graph. The singnificance of this study is to check the pavement at early stage failure and can reduce the cost of maintenance before the failure become very servere.
